Symantec Corp.'s Backup Exec is a well-liked facts backup application for computing device and networked storage methods. besides the fact that children, as with entire application, there are things that may furthermore exist set incorrectly or things that may vanish incorrect to exist able to sluggish performance. in the case of a backup software, a slipup can tremendously boost the time it takes to complete your backup jobs. if you're the usage of Backup Exec and your efficiency is never what it'll be, some troubleshooting could exist in order. here's a list of information things to view out for.Get a baseline: examine historical backup logs
delivery with the aid of your historical backup job logs and notice each the entire time required to back up, the measurement of the backups, and the overall speed. (Go to the "job video display" tab in Backup Exec and select "job historical past.") compare this to the current hurry and complete time it takes to comprehensive the job. If there may exist a significant slowdown, you are going to necessity to emerge extra carefully for viable reasons.
smash the process down and examine the pace of each disk or agent being backed up. To conclude that, deploy separate jobs for each and every disk or agent being backed up and returned them up one by one. If one disk or agent seems strangely slow, drill down to determine the trigger through inspecting the job in element.
examine that the facts is not being redirected in different places. Some file methods allow a directory to include facts from a file on a further server within the backup. this may late down the entire backup process.
if you are backing up over a network, you can view at various the system throughput by artery of comparing the Backup Exec logs with the logs of home windows backup (NTBackup) If the Backup Exec logs reflect a lot of situations that don't exhibit up within the NTBackup logs, extra evaluation is referred to as for. If far flung backups don't appear to exist working, are attempting backing up from one pressure to one more on the far flung server. compare the logs of the Backup Exec backup and the home windows backup. (This assumes you are inspecting a power in preference to an agent for a software relish Microsoft trade.)assess for disk fragmentation
be certain you additionally check that there don't appear to exist a lot of minute data or directories on the disk. this could late down backups in tons the equal means fragmentation does with the aid of requiring loads of reads to accept the guidance off the disk for backup.
Disk fragmentation can late efficiency of Backup Exec enormously. examine to view how fragmented your disks are and defragment if indispensable.flip compression on
tell the Backup Exec to compress any info which can exist compressed. Some files, relish mpegs and jpegs, can not exist compressed. in case you suspect the vicissitude may well exist within the compression, try switching from hardware to utility compression, or vice versa.make inevitable your backup application isn't poignant into the manner
Antivirus software can exist a specific issue in Backup Exec. Checking each file being backed up for viruses is mindless and slows backup efficiency. For greater on the interaction between Backup Exec and Norton Antivirus, survey Symantec's Backup Exec discussion board. also, the more moderen models of Backup Exec acquire a office known as Tamper insurance policy that can cause problems with antivirus software.Tape backup with Backup Exec
if you're backing as much as tape, energy cycle the tape power or library and the server. This should resolve transient issues. This re-initializes the tape gadget and resets the tape device's state. This may additionally remedy every diminutive thing from a problem caused through an influence glitch to a pair incorrectly set parameters.
The SCSI fraction (controllers, cables, terminators, and many others.) of your backup equipment can sap efficiency if the parameters are set incorrectly when backing up to tape. check the documentation and compare the values there with your settings. The determine option may soundless present you a much common image of the circumstance of the SCSI device. they could conclude the equal component when backing as much as disk, but as a result of the random write nature of disk, it doesn't acquire the vicissitude to the equal degree tape does. Tape needs statistics fed at a pleasant even velocity that fits the hurry of the tape unit for highest character performance. Disk can deal with intermittent slowdowns within the facts fee improved than tape can because it writes randomly.Use the 'determine' preference to assess the fitness of the SCSI system
The verify operation is generally limited with the aid of the pace of the SCSI gadget. investigate the performance by using analyzing the logs of jobs with assess operations in them. If the determine speeds are low, verify the SCSI subsystem for viable bottlenecks.
make certain your controller is rated for the hurry of your tape drive. as an example, an LTO-3 tape power requires a SCSI 320 network. determine that your tape drives are not linked to a SCSI RAID controller.
among the different feasible complications with SCSI are mistaken cabling, unfastened or unhealthy termination and flawed SCSI BIOS settings. additionally exist inevitable the "provoke broad negotiation" option is decided to "sure" when you are using a 68-pin cable connector to your tape power.
if you are backing up to disk, examine the Backup to Disk (B2D) folder. The B2D folder's main exhaust is to steer limpid of the necessity of data if a implement fails, but it surely offers a benchmark for Backup Exec in opposition t yet another machine. You want at the least 2 Gb of information to permit for caches and such. It tends to liquidate issues with the application and the server being backed up as viable explanations. view at various the B2D hurry via copying at the least 2 Gb of facts to the B2D disk by means of dragging and shedding the file(s). compare that with the pace of backing up the equal records. If the velocity is concerning the identical, the issue is definitely within the disk subsystem, together with the controller.
See Symantec's troubleshooting tip document for extra Backup Exec troubleshooting counsel.

This chapter, from Upgrading and Repairing Networks, 5e, looks at the network's analytic and physical design to assist your planning when creating a new network.This chapter is from the reserve
Many types of networks were discussed in Chapter 1, "A Short History of Computer Networking," from ARPANET to TCP/IP. And in Chapter 2, "Overview of Network Topologies," you erudite about the various topologies you can employ when designing and creating a local district network (LAN), and they furthermore looked at some scenarios in which several networks were connected to contour a wide district network (WAN). In this chapter, they will view at another aspect of creating a network: the network's analytic and physical design. The physical aspects of your LAN will depend on the underlying physical transport technology—Ethernet or Token-Ring, for example, or possibly ATM, which is supported as a LAN protocol in products such as Windows 2000/XP, Windows Server 2003, and Linux. Depending on which technology you use, there will exist one or more LAN topologies from which to choose.
Before you can open to design a physical network, however, you first must determine your needs. What services must you provide to your user community? What are the resources you'll need? If you acquire to compromise, what will it buy to fullfil the most users or to provide the more necessary services? You then will acquire to buy into account network protocols, applications, network speed, and, most important, network security issues; each of these figures into a network's analytic design. Another necessary factor your management will probably obligate you to reckon is cost—you can't forget the budget. These factors bear up the analytic design for your network. You first should resolve what you necessity and what it will buy to provide for those needs.
If you are creating a new network and purchasing new applications, you will probably spend most of your time considering the licensing and other monetary costs (training users, network personnel, and so on). If you are upgrading older applications, several other factors foster into consideration. Many applications that were coded using COBOL, BASIC, FORTRAN, and other languages that helped jumpstart the computer age may acquire built-in network functionality based on older proprietary network protocols. If this is the case with your network, you acquire to reckon several things. What will it cost to update thousands of lines of code (or more) to more modern versions of the very programming language? What will it cost to upgrade these programs to newer object-oriented languages? To redeem money, can you upgrade fraction of your network and exhaust gateway hardware/software to connect to older network components?
Because of the costs associated with coding applications that were created many years ago, and the expenses that will exist required to update them to modern programming languages, you may exist forced to maintain legacy applications for a few years while replacement applications are designed and created. You may find a packaged application that can exist used to replace older programs. This problem will apply mostly to proprietary computer architectures, instead of Windows or Unix platforms. If you can simply bear minor changes and compile the source code so that it will dash on a newer operating system, your costs will exist much less than if you acquire to re-create the applications your users necessity from scratch. Another cost associated with upgrading to new programs is training users and help-desk personnel.
When you design a analytic network design, you can start from one of two places. You can design and install a new network from scratch, or you can upgrade an existing network. Either way, you should assemble information about several necessary factors before you open the analytic design. For example, depending on the services that will exist provided to clients, you might necessity to anatomize the possible traffic patterns that might result from your plan. Locate potential bottlenecks and, where possible, alleviate them by providing multiple paths to resources or by putting up servers that provide replicas of necessary data so that load balancing can exist provided. The following are other factors to consider:
This seems relish a very simple question. However, I'm not saying, "What are your clients' names and how well conclude you know their children?" I am referring instead to your information of the job descriptions for the users on the network. You necessity to assess drudgery patterns for various departments so that you can appropriately residence servers, high-bandwidth links, and other such things in the usurp physical location of the network. If most of the network traffic you hope to survey will foster from the engineering department, you'll necessity to provide that department with a large data pipe. In Chapter 4, "Upgrading Strategies and Project Management," you'll find more information about surveying the user community to foster up with a design that places resources where they are needed.What Kinds of Services or Applications Will the Network Offer?
Of course, everyone knows that the most necessary office of a network today is to support multiuser gaming. Seriously, though, you necessity to bear a list of the kinds of applications currently in use, as well as a list of those requested by users. Each application should acquire a written risk assessment document that points out potential security problems, if any. Typical network applications today include FTP, telnet, and, of course, browsing the Web. There are "secure" versions of these applications and there are versions that leave a door wide open into your network. Whatever list of applications you chose to support over the network, maintain in humor two things:
A commonly overlooked artery for getting data files out of a network and onto the Internet is to simply forward the files as an attachment to an email. So if you mediate you've blocked file transfers by disabling FTP access through the firewall, this instance should exhibit that you really conclude necessity to conclude a thorough evaluation of any new application or service you will allow on the network. New applications should exist justified with facts that exhibit why they are needed. If an existing application can exist used to accomplish the very goal, why conclude you necessity another application? Should you retire the older application and exhaust a newer one? Pay attention to the details. And don't forget to test new applications to ensure that they discharge as expected. The very goes for older applications—will they drudgery on the new or upgraded network?
Lastly, conclude you monitor network usage? conclude you want to permit users to spend their days browsing the Net, or checking personal email while at work? Many companies acquire policies that apply to using the telephone for personal business. conclude you overlook this situation when giving users email capability? Are you preventing access to sites that are obviously not business-related?What Degree of Reliability conclude I Require for Each Network Link?
Just how much downtime is acceptable? For most users, the answer would exist zero. necessary components of your network, such as file servers, should acquire failing tolerance built in from the bottom up. In large servers, you'll find dual-redundant power supplies (each connected to a separate UPS), and disk arrays set up using RAID techniques to provide for data integrity in the event that a disk goes south. If a link between two offices needs to exist up 100% of the time, you should design for multiple links between the two sites to provide a backup capability. In this case, you furthermore can warrant the cost of the extra link by using load balancing so that network response time is improved. And, if you are using multiple links to remote sites, it's always a agreeable notion to acquire more than a sole path to the site. At one site this author worked at, there were redundant power lines bringing electricity into the site—side-by-side. If a tree falls, will it bring down one or both of those power lines?
Another technology that can exist used to provide an extra layer of redundancy, as well as high-speed access to storage devices, is the Storage district Network (SAN). A SAN is a network that is separate from the LAN and contains only storage devices and servers that necessity to access those devices. Because the network bandwidth is not shared with LAN users, multiple servers can access the very storage. If one server fails, other servers can exist configured to provide redundant access to the data. Also, the very RAID and other redundancy techniques used for storage devices that are directly attached to a server (such as the SCSI hardware and protocols) can exist used on a SAN.
The terms RAID and UPS are necessary in today's networks, as is the concept of load balancing and dual-redundant power supplies in large networks. You can find out more about RAID (Redundant Array Of Independent Disks) and UPSs (uninterruptible power supplies) by reading Chapter 5, "Protecting the Network: Preventative Maintenance Techniques." For more information about SANs, survey Chapter 11.
The conventional adage "If it ain't broke, don't fix it" doesn't apply to networks. You should always exist proactively looking for potential sole points of failure and doing something to fix them. By building redundancy into the network design at the start, you'll redeem yourself a lot of grief in the future.
Chapter 5 can give you more suggestions about using clustering, backups, uninterruptible power supplies, and other techniques that can maintain the network up and running.Choosing a LAN Protocol
Today the de facto protocol of preference has to exist TCP/IP. However, other protocols acquire their residence in some upright markets. In this book, they talk about NetWare. NetWare has been around so long that you might find you acquire no preference when designing an upgrade but to maintain using IPX/SPX, depending on the applications your network uses. However, even NetWare has moved toward using TCP/IP as the underlying protocol. This is basically the case for version 5.x and 6.x of NetWare. Older NetWare networks should upgrade, if possible, to one of these newer versions. If you will exist connecting the network to the Internet, TCP/IP will exist a necessity. Even if you don't hope to acquire an Internet connection, you'll find that choosing TCP/IP is a more practical preference today because most applications drudgery with it and there is a large market of trained professionals who can exist hired to manage a network built on TCP/IP. NetWare 6.x provides backward compatibility with IPX/SPX for the most part, but newer features such as the iPrint—which uses the Internet Printing Protocol—require TCP/IP.
In addition to transport protocols such as TCP/IP and IPX/SPX, you must reckon application protocols that can exist used on the network. For example, to simplify administering configuration information for a large number of computers, you might want to exhaust the Dynamic Host Configuration Protocol (DHCP), which is discussed in Chapter 28, "BOOTP and Dynamic Host Configuration Protocol (DHCP)." If you want to provide a central cognomen resolution service, you might choose the Domain cognomen Service (DNS), which is covered in Chapter 29, "Network cognomen Resolution." If you are going to operate a Windows network that has pre–Windows 2000/XP clients, you might necessity to exhaust the Windows Internet Naming Service (WINS) for backward compatibility.
So when thinking about a network protocol, recollect that it's not just one protocol you necessity to worry about. After you've decided which protocols are necessary, research the security implications of each.It's Virtually Universal: TCP/IP
For entire practical purposes, the measure LAN protocol today is TCP/IP. This is partly due to the rapid growth of the Internet, and the necessity of most businesses of having a Web presence, as well as the large number of vendors that acquire adopted this protocol suite. If your LAN is soundless using an older proprietary network protocol, you should seriously reckon what it would buy to upgrade to TCP/IP. Currently, TCP/IP version 4 is the most widely used protocol. In the future you can hope that the next version (IPv6) will start to find its artery from the core of the Internet out to the edge, where your network resides. While technologies such as Network Address Translation (NAT) are widely employed to remedy the problem associated with the limited address space provided by IPv4, IPv6 will enable a much larger address space. Combine that with Network Address Translation, and the long-term bets are going to exist on IPv6, or possibly some of the features that are fraction of IPv6. In addition to giving you a larger address space, IPv6 includes other necessary features. Those that will affect your network the most are security mechanisms, which will only become more necessary as Internet commerce continues to grow.
For a circumstantial introduction to TCP/IP, survey Chapter 24, "Overview of the TCP/IP Protocol Suite"; Chapter 25, "Basic TCP/IP Services and Applications"; and Chapter 27, "Troubleshooting Tools for TCP/IP Networks."
There is one very necessary judgement you should reckon TCP/IP as a LAN protocol: There are more trained professionals knowledgeable in TCP/IP than any other LAN protocol at this time. It is consuming to note that in Windows NT 3.51, the default network protocol was Microsoft's implementation of IPX/SPX (NWLink). In Windows NT 4.0 (and successive operating systems, from Windows 2000, XP, and Server 2003), the default network protocol is TCP/IP.
If your network is composed of several operating systems, from Windows to NetWare to Unix and Linux, then the bottom line is that TCP/IP is the lowest common denominator that will allow the easiest connectivity and interaction between entire of these. Even Microsoft's now-legacy NetBIOS/NetBEUI protocols acquire been adapted to dash over TCP/IP.Novell's NetWare Version 6.5
NetWare was perhaps the first attempt at seriously providing a LAN protocol that was easy to use. The basic file and print services offered by early versions of NetWare were much better than other solutions available at that time. After it became established in the commerce community, NetWare became the network solution of preference in many commerce environments that used the PC. Microsoft countered this success with its LANManager products, which were furthermore marketed by other vendors in their own way, such as the Pathworks solution from Digital equipment Corporation.
Today NetWare is a totally revamped solution to LAN connectivity. It provides many new features that are addressed to specifically bear exhaust of the Internet, and allow mobile users to connect to their home networks, as well as to enable NetWare users to bear connections to outside networks. For example, the iPrint feature enables NetWare users to print to a printer on a remote network. For example, instead of sending a catalog that may exist out of date in a month or so, you can exhaust iPrint to periodically forward specific information germane to each customer, by printing it directly to the customer's printer.
And NetWare's iFolder allows mobile users to synchronize data stored on remote computers (such as a laptop computer) with the data stored on the company's network. Microsoft and other vendors present similar features. However, the point to recollect is that if you already are a NetWare user, you don't acquire to toss out your existing investment and inch to a Microsoft network, or even a Unix/Linux environment. NetWare has changed as the market has changed, and you might find it less expensive to upgrade to NetWare 6.5 than to migrate to another platform. The bottom line involves not just the cost of migrating to another operating system, but the costs involved with retraining your network administrative personnel in new technology.
Because NetWare 6.5 is so tightly integrated with the IP protocol, and furthermore offers backward compatibility with IPX/SPX, admins for existing NetWare networks should reckon upgrading to NetWare 6.5 as well as considering other options.
If you want to inch to Linux, Novell makes it easy by incorporating an enhanced version of NetWare 6.5 and SuSE Linux into its Novell Open Enterprise Server. Open Enterprise Server supports both Linux and NetWare-specific software and features, enabling you to inch to Linux gradually.Other LAN/WAN Protocols
The distinction between LAN and WAN (wide district networking) protocols is ascend to blur. Ethernet was once considered to exist a LAN protocol. As time has passed, other technologies, such as Token-Ring, acquire become minor players in the LAN world. Yet the contradictory is True of Ethernet. It has grown from a modest specification endorsed by Intel, DEC, and other vendors, such that it now can exist considered a WAN protocol. The capabilities introduced by current LAN technologies are ascend to erode the differences between a LAN and a MAN (metropolitan district network). When the fourth edition of this reserve was published, Gigabit Ethernet was starting to tumble into the inexpensive scope of network topologies. That trend has continued and now 10Gigabit Ethernet (10GbE) is frequently being used in enterprise data centers. Today you may exist using 100BASE-T for connecting client computers to the network, and Gigabit Ethernet to connect network segments via the network backbone. In some cases your network might even exist exclusively based on 10GbE.
What does this stand for to a network administrator today? With 10Gigabit Ethernet, you can exhaust TCP/IP not only to create a local district network backbone, but to extend that attain to a metropolitan district network. And because TCP/IP is so intertwined with Ethernet, you can achieve an end-to-end MAN link that uses TCP/IP over faster Ethernet connections. Instead of employing more expensive solutions, such as SONET, you can now connect fork offices in the very geographical district using just TCP/IP.
You may not acquire to worry about installing expensive equipment used by SONET and other typical MAN protocols. Still, for the long haul—for example, between different cities—other protocols such as ATM and Frame Relay will foster into play.
For more information about SONET, ATM, and Frame Relay, survey Chapter 15, "Dedicated Connections."

Posted January 23, 2019
When it's time to implement a cataclysm recovery plan, storage administrators are faced with the job of protecting necessary corporate data off site and making adequate preparations to resume bona fide commerce operations in the event of an emergency. This may appear relish a reasonably straightforward objective, but choosing the perquisite infrastructure can prove unwieldy. A wide proliferation of storage technologies bear the preference of platform difficult, and software choices must often accommodate a heterogeneous storage environment that is frequently separated by a large geographic distance. This article outlines many of the tools and technologies that are currently available for cataclysm recovery (DR) applications and examines some future directions of DR.
Setting recovery objectives
Before any cataclysm design can exist implemented, it is absolutely critical to establish the recovery requirements. This involves a thorough understanding of your applications and the artery they relate to everyday business.
Data classification plays a fraction in cataclysm planning. Not entire data is created equal -- the company's Oracle database or Exchange platform may exist mission-critical, but a repository of PowerPoint presentations may not exist essential to the commerce in the event of disaster. The first step is to identify the applications and data sets that should exist protected by a DR plan. Classifying data for DR carries a twist. "Storage classification is more around usage, access and so forth, while DR is more around linkage to commerce functions, risk mitigation and survivability versus how the storage is being used," says Greg Schulz, founder and senior analyst at StorageIO Group.
Once you understand the applications that necessity DR protection, you'll necessity to set a recovery point objective (RPO) and recovery time objective (RTO) for each one. The RPO essentially defines how much data you can afford to lose, while the RTO defines just how much time you acquire to regain from the disaster. RPO, and to a lesser extent RTO, will influence the technologies and costs involved in your DR plan. "For example, mediate about American Express having to recount Macy's it just lost the terminal 1,000 transactions that came out of its stores," says Pierre Dorion, senior commerce continuity consultant at Mainland Information Systems Inc. "It wouldn't forward Amex [American Express] filing for Chapter 11, but it certain would leave them with a sedate black eye!"
Making DR work
No two DR plans are identical. Each strategy must exist formulated to match unique commerce needs and legal requirements while accounting for the most likely "disaster" scenarios. While needs and plans can vary dramatically, most draw from the very selection of underlying technologies. A DR design will often include a merge of several different technologies.
Backup. Traditional backups are soundless the foundation of many DR plans, leveraging existing tape drives or libraries to copy crucial files to tape media that can then exist taken off site to a protected location. Disk-based backups are systematically replacing tape, bringing better hurry and reliability to the backup process. Backups can exist made to any disk array or other platform, but virtual tape has emerged as a current alternative when disk technology must emulate tape. Backups can exist made locally on site but can furthermore exist made to off-site locations across a WAN link.
Mirroring/replication. This disk-to-disk process simply creates a data copy between two disk platforms. When inconvenience strikes the original copy, data can exist restored from the replicated copy -- or possibly even accessed directly from the mirror. As with backups, mirroring between disks can exist handled locally within the data headquarters or between disks across a WAN link. Most storage array products provide mirroring/replication software utilities bundled with the product.
Snapshot. A snapshot creates an index of entire data locations on the storage platform and tracks any subsequent changes to the data at each location. Over time, a running log of storage changes develops, allowing administrators to restore files and folders that may become lost or corrupted. Since the amount of storage space needed to maintain an index file is limited, it is only possible to store a finite number of snapshots. Consequently, snapshots are typically employed as a short-term protective tactic. Snapshots are basically just a list of data locations and conclude not back up data to a second location, so it is soundless necessary to protect data through sporadic backups or replication.
WAN/WAFS. cataclysm planning usually demands that data copies exist stored in a location separate from the original -- if fire destroys the data center, a viable copy of the data is soundless available. Today, WAN links are used to backup or restore data directly between remote sites. For example, remote offices might back up their servers to the primary data headquarters each night using fractional T3 WAN links, mobile users can back up their laptops to the data headquarters across the broadband Internet or a data headquarters might replicate its main servers to a backup data headquarters across an OC3 connection.
WAFS is an emerging technology for IT centralization, allowing remote offices "local-like" access to applications and data from the primary data headquarters across a WAN link. WAFS is not directly considered a DR technology, but has an repercussion on remote office IT consolidation, which will influence DR strategies.
Virtualization. The demand for duplicate equipment can impose a significant cost for DR users. For example, an EMC Corp. Centera in the primary data headquarters may necessity another EMC Centera at the remote location. Virtualization technology abstracts the hardware, usually allowing data to reside and operate on different hardware at the remote location. This gives organizations the option to deploy used or available hardware, rather than purchasing identical storage hardware for the remote site.
CDP. Continuous data protection maintains a running log of storage changes based on key events or even down to individual I/O operations. This type of continuous operation reduces the RPO to almost zero, and administrators can regain lost or corrupted data from disk in an extremely short timeframe -- keeping RTO short. CDP is not generally intended as a DR technology but is increasingly employed to protect sedulous networks (e.g. retail or data processing operations) against lost transactions. As with snapshots, data on a CDP platform soundless needs to exist backed up.
CAS. Data that requires only occasional access is sometimes archived to a disk-based content-addressed storage (CAS) device. Unlike ordinary disk platforms, CAS devices typically include security features to preclude file alteration/tampering, compliance features to ensure file availability for a prescribed retention epoch and data deduplication (a.k.a. "intelligent compression") features that optimize disk space utilization by eliminating redundant data. CAS devices are mainly intended for long-term archival storage but are sometimes used for disk-based backup purposes.
Turning to tools
Any DR strategy has to start with a solid plan, but it's the hardware and software that swirl plans into reality. Hardware goes beyond the disks, supporting advanced storage features relish mirroring/replication, snapshots or CDP. Hardware furthermore plays a vital role in poignant data across a WAN, allowing synchronous or asynchronous data movement and often providing compression and data deduplication capabilities that optimize bandwidth use.
Analysts point to the DMX from EMC as a leading enterprise storage product for DR, citing robust storage and mirroring/replication that handles multisite configurations. The DMX furthermore supports synchronous and asynchronous data movement and multivolume data handling to maintain data integrity between multiple sites. Other leading storage hardware products for DR include the NearStor virtual tape library (VTL) from Network Appliance Inc., and the TagmaStore storage array from Hitachi Data Systems Inc.
Cisco Systems Inc. is another notable DR hardware vendor, providing a variety of network routers and switches that support local, metropolitan and wide-area data movement using technologies relish SONET/SDH, DWDM and IP -- necessary technologies for synchronous and asynchronous data movement. Brocade Communication Systems Inc. furthermore specializes in switching hardware, such as the SilkWorm family of director switches.
Tape soundless plays a role in DR for many organizations. Products relish the L1400M tape library from Sun Microsystems Inc. (StorageTek) and the PX720 tape library from Quantum Corp. wield backup and archiving within the data headquarters and between sites.
Heterogeneous support is increasingly necessary when selecting storage equipment, ensuring that a new manufacturer's product will interoperate properly with existing products in the data center. In many cases, heterogeneous products can exist configured and maintained using existing management software, easing integration problems for new systems. Products are often evaluated in foster to guarantee interoperability.
Backup software and DR
Software tools furthermore deserve sedate consideration in any DR plan, bringing organization and management features to the users that must implement and oversee DR operations. Although there are many types of backup software available for the enterprise, the tools used for DR must exist particularly easy to use, especially in terms of rapid recovery. DR software must furthermore exist flexible, adaptable, interoperable and scalable. In short, it must exist able to grow and change as the DR environment evolves.
NetBackup from Symantec Corp. (Veritas) is perhaps the most recognized backup implement for DR applications. Capable of working with disk and tape platforms, NetBackup can operate enterprise-wide backup and recovery tasks regardless of geographic location using a sole console under UNIX, Windows, Linux and NetWare. NetWorker from EMC Legato, Tivoli Storage Manager from IBM and Galaxy Backup & Recovery from CommVault Systems Inc. are three other notable backup/recovery products selected for DR tasks.
DR planning software
However, software considerations vanish beyond backup. Software tools are available to wait on organizations develop and maintain their DR plan. In most cases, these tools are intended to track hardware in the production and DR environments, ensuring that storage arrays, SAN switches, tape drives, servers and other devices are entire available and functioning as expected. TeraCloud Corp.'s Storage Framework and Onaro Inc.'s SANScreen are two notable products that assemble and report this type of information. Sentric's Destiny product is an emerging product that classifies and reports data on email servers, file servers and database servers.
Aside from infrastructure tracking tools, there are several tools available that can actually wait on organizations develop and manage their specific plans. For example, RecoveryPlanner from RecoveryPlanner.com provides DR planners with Web-based software for design creation, distribution and management over the Internet. It furthermore includes notification services, so responsible individuals can exist kept informed throughout the cataclysm and recovery process. Similarly, Strohl Systems Group Inc. offers its vital cataclysm Recovery Planning System software to wait on users develop comprehensive commerce continuity plans.
The future of DR
Disaster recovery strategies are shifting away from "backups" and poignant toward the concepts of "recovery" and "continuance." The trend toward continuance should continue as organizations set their sights on uninterrupted commerce operations. fraction of this trend is due to the continued evolution of technology in storage platforms relish VTL, CDP and snapshots. This is further supported by improved bandwidth utilization using features such as brilliant compression (a.k.a. data deduplication), allowing companies to exchange more data over greater distances in less time. For example, data can exist backed up directly to a VTL located hundreds of miles away, then transferred to a tape library for off-site tape storage.
Analysts survey the inch toward lower costs, better integration and easier management. Emerging products relish Bycast Inc.'s StorageGRID are recognized for storing and replicating data between multiple sites. "I believe this is the future of DR in terms of delivering data where and when you necessity it so that even a geographic cataclysm is not the very level of concern it is now," says Jerome Wendt, independent storage analyst. Analysts furthermore view to startups to significantly accelerate replication speeds in 2007.
Virtualization is furthermore likely to play a central role in future DR strategies. By adopting virtualization, hardware requirements become less stringent between sites -- with fewer potential configuration and set up problems to impair recovery. "Server virtualization is a huge enabler of DR," says Stephen Foskett, director of strategy services at GlassHouse Technologies Inc. "Many companies are sending VMware images off site so that they don't acquire to acquire exactly the very hardware waiting for them on the other end."
Consider the role of third-party DR service providers. Although DR services acquire not been terribly current over the terminal few years, a resurgence may exist on the horizon. "SunGard, Iron Mountain Inc. or IBM Global may foster back into favor because organizations may not acquire a second location," says Brian Babineau, analyst at the Enterprise Strategy Group. He suggests that the economics of outside DR services may bear sense for smaller enterprises that necessity the budget and staff to deploy and maintain an in-house DR system.
