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 all application, there are things that may also be set incorrectly or things that may go incorrect to be 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 be in order. here's a list of knowledge things to look 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 speed and complete time it takes to comprehensive the job. If there may be a significant slowdown, you are going to need to appear extra carefully for viable reasons.
smash the process down and examine the pace of each disk or agent being backed up. To do 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 slow down the entire backup process.
if you are backing up over a network, you can look at various the system throughput by way 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 seem to be 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 like Microsoft trade.)assess for disk fragmentation
be sure you additionally check that there don't seem to be a lot of small data or directories on the disk. this could slow down backups in tons the equal means fragmentation does with the aid of requiring loads of reads to get the guidance off the disk for backup.
Disk fragmentation can slow efficiency of Backup Exec enormously. examine to look how fragmented your disks are and defragment if indispensable.flip compression on
tell the Backup Exec to compress any info which can be compressed. Some files, like mpegs and jpegs, can not be compressed. in case you suspect the difficulty may well be within the compression, try switching from hardware to utility compression, or vice versa.make certain your backup application isn't moving into the manner
Antivirus software can be 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, see Symantec's Backup Exec discussion board. also, the more moderen models of Backup Exec have a function 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 little thing from a problem caused through an influence glitch to a couple incorrectly set parameters.
The SCSI part (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 still offer you a great general image of the circumstance of the SCSI device. they could do the equal component when backing as much as disk, but as a result of the random write nature of disk, it doesn't have the difficulty to the equal degree tape does. Tape needs statistics fed at a pleasant even velocity that fits the speed of the tape unit for highest quality performance. Disk can deal with intermittent slowdowns within the facts fee improved than tape can because it writes randomly.Use the 'determine' choice 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 sure your controller is rated for the speed 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 be certain 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 use is to steer clear of the lack of data if a tool 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 eliminate issues with the application and the server being backed up as viable explanations. look at various the B2D speed 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 logical and physical design to assist your planning when creating a new network.This chapter is from the book
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 learned about the various topologies you can employ when designing and creating a local area network (LAN), and we also looked at some scenarios in which several networks were connected to form a wide area network (WAN). In this chapter, we will look at another aspect of creating a network: the network's logical 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 be one or more LAN topologies from which to choose.
Before you can begin 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 have to compromise, what will it take to satisfy the most users or to provide the more important services? You then will have to take into account network protocols, applications, network speed, and, most important, network security issues; each of these figures into a network's logical design. Another important factor your management will probably force you to consider is cost—you can't forget the budget. These factors make up the logical design for your network. You first should decide what you need and what it will take 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 financial costs (training users, network personnel, and so on). If you are upgrading older applications, several other factors come into consideration. Many applications that were coded using COBOL, BASIC, FORTRAN, and other languages that helped jumpstart the computer age may have built-in network functionality based on older proprietary network protocols. If this is the case with your network, you have to consider several things. What will it cost to update thousands of lines of code (or more) to more modern versions of the same programming language? What will it cost to upgrade these programs to newer object-oriented languages? To save money, can you upgrade part of your network and use 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 be required to update them to modern programming languages, you may be forced to maintain legacy applications for a few years while replacement applications are designed and created. You may find a packaged application that can be used to replace older programs. This problem will apply mostly to proprietary computer architectures, instead of Windows or Unix platforms. If you can simply make minor changes and compile the source code so that it will run on a newer operating system, your costs will be much less than if you have to re-create the applications your users need from scratch. Another cost associated with upgrading to new programs is training users and help-desk personnel.
When you plan a logical 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 gather information about several important factors before you begin the logical design. For example, depending on the services that will be provided to clients, you might need to analyze 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 important data so that load balancing can be provided. The following are other factors to consider:
This seems like a very simple question. However, I'm not saying, "What are your clients' names and how well do you know their children?" I am referring instead to your knowledge of the job descriptions for the users on the network. You need to assess work patterns for various departments so that you can appropriately place servers, high-bandwidth links, and other such things in the appropriate physical location of the network. If most of the network traffic you expect to see will come from the engineering department, you'll need 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 come up with a plan that places resources where they are needed.What Kinds of Services or Applications Will the Network Offer?
Of course, everyone knows that the most important function of a network today is to support multiuser gaming. Seriously, though, you need to make a list of the kinds of applications currently in use, as well as a list of those requested by users. Each application should have 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, keep in mind two things:
A commonly overlooked method for getting data files out of a network and onto the Internet is to simply send the files as an attachment to an email. So if you think you've blocked file transfers by disabling FTP access through the firewall, this example should show that you really do need to do a thorough evaluation of any new application or service you will allow on the network. New applications should be justified with facts that show why they are needed. If an existing application can be used to accomplish the same goal, why do you need another application? Should you retire the older application and use a newer one? Pay attention to the details. And don't forget to test new applications to ensure that they perform as expected. The same goes for older applications—will they work on the new or upgraded network?
Lastly, do you monitor network usage? Do you want to permit users to spend their days browsing the Net, or checking personal email while at work? Many companies have policies that apply to using the telephone for personal business. Do 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 Do I Require for Each Network Link?
Just how much downtime is acceptable? For most users, the answer would be zero. Important components of your network, such as file servers, should have fault 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 be up 100% of the time, you should plan for multiple links between the two sites to provide a backup capability. In this case, you also can justify 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 good idea to have more than a single 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 be used to provide an extra layer of redundancy, as well as high-speed access to storage devices, is the Storage Area Network (SAN). A SAN is a network that is separate from the LAN and contains only storage devices and servers that need to access those devices. Because the network bandwidth is not shared with LAN users, multiple servers can access the same storage. If one server fails, other servers can be configured to provide redundant access to the data. Also, the same RAID and other redundancy techniques used for storage devices that are directly attached to a server (such as the SCSI hardware and protocols) can be used on a SAN.
The terms RAID and UPS are important 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, see Chapter 11.
The old saying "If it ain't broke, don't fix it" doesn't apply to networks. You should always be proactively looking for potential single points of failure and doing something to fix them. By building redundancy into the network design at the start, you'll save 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 keep the network up and running.Choosing a LAN Protocol
Today the de facto protocol of choice has to be TCP/IP. However, other protocols have their place in some vertical markets. In this book, we talk about NetWare. NetWare has been around so long that you might find you have no choice when designing an upgrade but to keep 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 be connecting the network to the Internet, TCP/IP will be a necessity. Even if you don't expect to have an Internet connection, you'll find that choosing TCP/IP is a more practical choice today because most applications work with it and there is a large market of trained professionals who can be 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 consider application protocols that can be used on the network. For example, to simplify administering configuration information for a large number of computers, you might want to use 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 name resolution service, you might choose the Domain Name Service (DNS), which is covered in Chapter 29, "Network Name Resolution." If you are going to operate a Windows network that has pre–Windows 2000/XP clients, you might need to use the Windows Internet Naming Service (WINS) for backward compatibility.
So when thinking about a network protocol, remember that it's not just one protocol you need to worry about. After you've decided which protocols are necessary, research the security implications of each.It's Virtually Universal: TCP/IP
For all practical purposes, the standard 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 have adopted this protocol suite. If your LAN is still using an older proprietary network protocol, you should seriously consider what it would take to upgrade to TCP/IP. Currently, TCP/IP version 4 is the most widely used protocol. In the future you can expect that the next version (IPv6) will start to find its way 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 be on IPv6, or possibly some of the features that are part of IPv6. In addition to giving you a larger address space, IPv6 includes other important features. Those that will affect your network the most are security mechanisms, which will only become more important as Internet commerce continues to grow.
For a detailed introduction to TCP/IP, see 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 important reason you should consider 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 interesting 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 all of these. Even Microsoft's now-legacy NetBIOS/NetBEUI protocols have been adapted to run 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 business community, NetWare became the network solution of choice in many business environments that used the PC. Microsoft countered this success with its LANManager products, which were also 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 make use of the Internet, and allow mobile users to connect to their home networks, as well as to enable NetWare users to make 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 be out of date in a month or so, you can use iPrint to periodically send specific information relevant 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 offer similar features. However, the point to remember is that if you already are a NetWare user, you don't have to throw out your existing investment and move 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 also offers backward compatibility with IPX/SPX, admins for existing NetWare networks should consider upgrading to NetWare 6.5 as well as considering other options.
If you want to move 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 move to Linux gradually.Other LAN/WAN Protocols
The distinction between LAN and WAN (wide area networking) protocols is beginning to blur. Ethernet was once considered to be a LAN protocol. As time has passed, other technologies, such as Token-Ring, have become minor players in the LAN world. Yet the opposite is true of Ethernet. It has grown from a modest specification endorsed by Intel, DEC, and other vendors, such that it now can be considered a WAN protocol. The capabilities introduced by current LAN technologies are beginning to erode the differences between a LAN and a MAN (metropolitan area network). When the fourth edition of this book was published, Gigabit Ethernet was starting to fall into the inexpensive range of network topologies. That trend has continued and now 10Gigabit Ethernet (10GbE) is frequently being used in enterprise data centers. Today you may be 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 be exclusively based on 10GbE.
What does this mean to a network administrator today? With 10Gigabit Ethernet, you can use TCP/IP not only to create a local area network backbone, but to extend that reach to a metropolitan area 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 branch offices in the same geographical area using just TCP/IP.
You may not have 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 come into play.
For more information about SONET, ATM, and Frame Relay, see Chapter 15, "Dedicated Connections."

Posted January 23, 2019
When it's time to implement a disaster recovery plan, storage administrators are faced with the task of protecting important corporate data off site and making adequate preparations to resume normal business operations in the event of an emergency. This may seem like a reasonably straightforward objective, but choosing the right infrastructure can prove unwieldy. A wide proliferation of storage technologies make the choice 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 disaster recovery (DR) applications and examines some future directions of DR.
Setting recovery objectives
Before any disaster plan can be implemented, it is absolutely critical to establish the recovery requirements. This involves a thorough understanding of your applications and the way they relate to everyday business.
Data classification plays a part in disaster planning. Not all data is created equal -- the company's Oracle database or Exchange platform may be mission-critical, but a repository of PowerPoint presentations may not be essential to the business in the event of disaster. The first step is to identify the applications and data sets that should be 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 business 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 need DR protection, you'll need 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 have to recover from the disaster. RPO, and to a lesser extent RTO, will influence the technologies and costs involved in your DR plan. "For example, think about American Express having to tell Macy's it just lost the last 1,000 transactions that came out of its stores," says Pierre Dorion, senior business continuity consultant at Mainland Information Systems Inc. "It wouldn't send Amex [American Express] filing for Chapter 11, but it sure would leave them with a serious black eye!"
Making DR work
No two DR plans are identical. Each strategy must be formulated to match unique business needs and legal requirements while accounting for the most likely "disaster" scenarios. While needs and plans can vary dramatically, most draw from the same selection of underlying technologies. A DR plan will often include a mix of several different technologies.
Backup. Traditional backups are still the foundation of many DR plans, leveraging existing tape drives or libraries to copy crucial files to tape media that can then be taken off site to a protected location. Disk-based backups are systematically replacing tape, bringing better speed and reliability to the backup process. Backups can be made to any disk array or other platform, but virtual tape has emerged as a popular alternative when disk technology must emulate tape. Backups can be made locally on site but can also be 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 trouble strikes the original copy, data can be restored from the replicated copy -- or possibly even accessed directly from the mirror. As with backups, mirroring between disks can be handled locally within the data center 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 all 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 do not back up data to a second location, so it is still important to protect data through periodic backups or replication.
WAN/WAFS. Disaster planning usually demands that data copies be stored in a location separate from the original -- if fire destroys the data center, a viable copy of the data is still 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 center each night using fractional T3 WAN links, mobile users can back up their laptops to the data center across the broadband Internet or a data center might replicate its main servers to a backup data center 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 center across a WAN link. WAFS is not directly considered a DR technology, but has an impact 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 center may need 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 recover 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 busy networks (e.g. retail or data processing operations) against lost transactions. As with snapshots, data on a CDP platform still needs to be 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 prevent file alteration/tampering, compliance features to ensure file availability for a prescribed retention period 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 turn plans into reality. Hardware goes beyond the disks, supporting advanced storage features like mirroring/replication, snapshots or CDP. Hardware also plays a vital role in moving 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 also 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 like SONET/SDH, DWDM and IP -- important technologies for synchronous and asynchronous data movement. Brocade Communication Systems Inc. also specializes in switching hardware, such as the SilkWorm family of director switches.
Tape still plays a role in DR for many organizations. Products like the L1400M tape library from Sun Microsystems Inc. (StorageTek) and the PX720 tape library from Quantum Corp. handle backup and archiving within the data center and between sites.
Heterogeneous support is increasingly important 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 be configured and maintained using existing management software, easing integration problems for new systems. Products are often evaluated in advance to guarantee interoperability.
Backup software and DR
Software tools also deserve serious 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 be particularly easy to use, especially in terms of rapid recovery. DR software must also be flexible, adaptable, interoperable and scalable. In short, it must be able to grow and change as the DR environment evolves.
NetBackup from Symantec Corp. (Veritas) is perhaps the most recognized backup tool 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 single 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 go beyond backup. Software tools are available to help 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 all available and functioning as expected. TeraCloud Corp.'s Storage Framework and Onaro Inc.'s SANScreen are two notable products that gather 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 help organizations develop and manage their specific plans. For example, RecoveryPlanner from RecoveryPlanner.com provides DR planners with Web-based software for plan creation, distribution and management over the Internet. It also includes notification services, so responsible individuals can be kept informed throughout the disaster and recovery process. Similarly, Strohl Systems Group Inc. offers its Living Disaster Recovery Planning System software to help users develop comprehensive business continuity plans.
The future of DR
Disaster recovery strategies are shifting away from "backups" and moving toward the concepts of "recovery" and "continuance." The trend toward continuance should continue as organizations set their sights on uninterrupted business operations. Part of this trend is due to the continued evolution of technology in storage platforms like VTL, CDP and snapshots. This is further supported by improved bandwidth utilization using features such as intelligent compression (a.k.a. data deduplication), allowing companies to exchange more data over greater distances in less time. For example, data can be backed up directly to a VTL located hundreds of miles away, then transferred to a tape library for off-site tape storage.
Analysts see the move toward lower costs, better integration and easier management. Emerging products like 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 need it so that even a geographic disaster is not the same level of concern it is now," says Jerome Wendt, independent storage analyst. Analysts also look to startups to significantly accelerate replication speeds in 2007.
Virtualization is also 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 have to have exactly the same hardware waiting for them on the other end."
Consider the role of third-party DR service providers. Although DR services have not been terribly popular over the last few years, a resurgence may be on the horizon. "SunGard, Iron Mountain Inc. or IBM Global may come back into favor because organizations may not have a second location," says Brian Babineau, analyst at the Enterprise Strategy Group. He suggests that the economics of outside DR services may make sense for smaller enterprises that lack the budget and staff to deploy and maintain an in-house DR system.
