Virtual Tape Library Overview


D2D2T CONFIGURATIONSIn addition to disk-to-disk configurations, the FalconStor VTL software supportsthree possible disk-to-disk-to-tape (D2D2T) configurations to simplify managingboth virtual tapes and physical tapes.

Standard Configuration The backup application runs on a backup serveror on the nTier VTL server and manages all tapes, both virtual and physical.Data is copied to physical tape using the backup applications tape copyfunction.

Advanced Configuration The backup application runs on a backupserver and manages the backup to virtual tape. The VTL software managesthe disk storage and the export of data to the physical tape library.

Automated Tape Caching Configuration The backup application runson a backup server and transparently manages the backup to virtual tape. Inaddition, this configuration provides the backup application with transparentaccess to data regardless of whether the data is on disk or on tape. Flexiblemigration policies determine when data will be moved to physical tape.

Each configuration consists of one or more existing third party backupapplications, the nTier VTL appliance with the RAID disk storage managed by theVTL software used as virtual tapes in a virtual tape library, and one or morephysical tape libraries. From the perspective of the backup applications, the virtualtape library is managed as just another tape library attached to the backup server.Tapes, both virtual and physical, are treated the same way: a virtual tape is justanother tape .

Regardless of which configuration you choose, VTL makes it easy for you tomanage both virtual tapes and physical tapes.


23/367

Standard VTL Configuration


STANDARD VTL CONFIGURATIONIn the standard VTL configuration, the backup application manages the entirebackup process. Data is copied from virtual tape to physical tape using the backupapplications tape copy function. With the backup application managing the entirebackup process, virtual tapes and physical tapes are seen in the same way: a

virtual tape is just another tape .In the standard VTLconfiguration, the backupapplication runs on an existingbackup server (or on thenTier VTL server using theHosted Backup option). Thisconfiguration is ideal fororganizations that alreadyhave a backup process inplace that, while functional,does not meet all of theirbackup objectives. Becausethe VTL can emulate moretape drives than a physicaltape library really has, morebackup streams can runsimultaneously, enabling theorganization to easilycomplete their backups within

the allotted backup window. In addition, the VTL provides rapid data recovery fromthe virtual tapes without having to alter the current configuration.

With the standard VTL configuration, backups to virtual tapes occur quickly. Then,at a later time, the backup application copies the data from virtual to physicaltapes without impacting the production environment. Because the backup serverperforms the tape copying function in addition to backups, additional overheadcan be incurred by the backup server. Therefore, it is best to perform tape copyingat off-peak hours.

Installing a backup application on the nTier VTL server (Hosted Backup)accelerates backups to virtual tape by eliminating the need for a backup server.This shortens the data path between the application server and the backupapplication/server and therefore enhances backup performance.


24/367

Virtual Tape Library Overview


A DVANCED VTL CONFIGURATIONIn the advanced VTL configuration, the backup application manages backups tothe virtual tape while the VTL software running on the nTier VTL appliancecontrols the export of data from virtual tapes to physical tapes.

In this configuration, the VTLdramatically acceleratesbackups by acting as a defacto cache for a physical tapelibrary. After the backupapplication writes data tovirtual tape, the VTL softwaremanages the export of thedata to physical tape as abackground process. Thisinnovative approach reduces theimpact on the production serversand eliminates the additionaloverhead created by runningthe tape copy process on thebackup server.

As with the standard VTLconfiguration, the backupapplication runs on an existingbackup server (or on thenTier VTL appliance with theHosted Backup option) andmanages the initial backup tovirtual tape. The backups tovirtual tape occur very quickly.

Unlike the standard VTL configuration, with the advanced configuration thetransfer of data to physical tape is managed by the VTL software. This makes itpossible to export data to physical tape for offsite vaulting or disaster recoverywithout impacting the production environment. The VTL can also be set up in Auto

Archive mode so that after each backup to virtual tape completes, data isautomatically exported to physical tape.

The advanced VTL configuration requires you to create virtual tapes that emulatethe physical tapes so that there is a 1:1 mapping, with identical barcodes,between the virtual and physical tapes. This enables the backup application tokeep track of backup tapes and prevents tapes from being created that would beunidentifiable by the backup application. Because the physical tape and its virtualtape counterpart always have the same barcode, you have the flexibility to easilyrestore from either virtual or physical tape.


25/367

Automated Tape Caching VTL Configuration


Whenever data is written to physical tape, the virtual tape can either be deleted orretained in the VTL for rapid data recovery. When it comes time to restore, thebackup application identifies the barcode of the tape containing the needed data.If the data still resides on virtual tape (that is, it was never exported or it wasexported and the virtual tape was retained in the VTL), it can be restored veryquickly because it is read directly from disk. If the data is only on physical tape, thetape must first be re-imported into the VTL using a few simple keystrokes in the

VTL Console. The backup application can then access the data and restore in itsusual manner.

A UTOMATED T APE C ACHING VTL CONFIGURATION Automated tape cachingprovides transparent access todata, independent of where thedata is stored. With AutomatedTape caching, tapes always

appear to be inside the virtuallibrary and are visible to thebackup application regardlessof whether the data is actuallyon virtual tape or physical tape.This means that the backupapplication always has directaccess to data.

In this configuration, thebackup application runs on anexisting backup server and

transparently manages thebackup of data to virtual tape,dramatically acceleratingbackups. The VTL acts as acache to the physical tapelibrary, automatically writing thedata to physical tape as atransparent backgroundoperation. The transfer of datafrom virtual tape to physicaltape is based on extremely

flexible migration policies (age of data, time of day, disk space, end of backup, and

so forth). Because the process operates in the background, it does not impact theperformance of the production servers. The Automated Tape Cachingconfiguration also provides very flexible space reclamation policies (for example,the policy can free space immediately, upon migration, after a specified retentionperiod, or when the system runs out of space).

3. Right-click the Virtual Tape Libraries object and select New to launch theCreate Virtual Library wizard. The first screen that displays depends onwhether you previously assigned one or more physical libraries to the VTL(see Assign Physical Libraries and Drives ).

When selecting the physical library to emulate, keep the followingconsiderations in mind:

If you have a physical tape library, create a virtual tape library thatresembles it to ensure that the virtual tapes use the same format as the

physical tapes. Having the same format for the virtual tapes and thephysical tapes is important for importing and exporting functions andguarantees that your backup application will accept the tapes.

For example, if you have a Spectra T380 library physically connected tothe nTier VTL appliance, select a Spectra T380 from the list of virtuallibraries.

If you assigned a physical tape library to your VTL, the Create equivalenttape caching virtual library option is also available. When you choosethis option, only the physical libraries that have not already beenassigned to another VTL are listed. The resulting equivalent virtuallibrary is automatically configured to use the VTL Automated TapeCaching option. See Using Automated Tape Caching for detailedinformation about configuring Automated Tape Caching.

6. Select Next to begin configuring the virtual tape library. As you progressthrough the virtual tape library configuration, enable and configure thefollowing options as desired. See Configure the Virtual Library Options fordetailed information about these options.

7. Configure the number of slots in the library and information about the virtualtapes the library will use.

Barcode information

Tape properties such as Tape Capacity On Demand and maximum tapecapacity.

Note: If you plan to use deduplication with the virtual tape library, using theTape Capacity On Demand option is h igh ly r ecom mended .

8. Click Next to review your configuration settings, then click Finish to create thenew virtual tape library.

9. Click OK when the message box indicating that the library has been created

displays.10. After you create the virtual library, you will be prompted to create new virtual

tapes. Click Yes, then continue to Create Virtual Tapes to create one or morevirtual tapes for the library.

Note: If you do not want to create virtual tapes at this time, click No to exit thewizard. You will need to create virtual tapes for the library before youcan use it. See Create Virtual Tapes in the Using Tape Libraries, TapeDrives, and Tapes chapter for detailed instructions.

Create Virtual Tapes After you finish creating a new virtual tape library, you have the option toimmediately launch the Create Virtual Tapes wizard and create one or more virtualtapes for the library.

1. Choose whether you want to use the Custom or Express method for creatingtapes.

Option Description

Automated Tape Caching If you enable this option, you will configure the migration

policies and reclamation triggers. Auto Archive/Replication If you enable this option, you will choose either Auto

Archive or Replication and configure how theseoperations are performed.

Tape Duplication If you have a physical library assigned to the nTier VTLappliance, you can configure the number of duplicatetapes to create and how they are labeled.Note: You cannot enable this option if a physical library isnot assigned to the nTier VTL appliance.

By default, the Create Virtual Tape wizard uses the Express method forcreating virtual tapes. If the Advanced Tape Creation method is enabled (seeConfigure VTL Console Options ), you can choose to use either the Expressmethod or the Custom method for creating virtual tapes. See Create VirtualTapes in the Using Tape Libraries, Tape Drives, and Tapes chapter fordetailed information.

Notes: If the Advanced Tape Creation method is not enabled, the screenfor choosing the method does not display.If you plan to export virtual tapes to physical tapes using either the

Automated Tape Caching or Auto Archive options, you must enable Advanced Tape Creation so that you can create virtual tapes thathave bar codes that are identical to those on the correspondingphysical tapes.

2. Enter the initial size and number of tapes you want to create.

Virtual Tape Size Set the initial size for the virtual tapes.

Number of Virtual Tapes Enter the number of tapes you want tocreate. The maximum number of tapes depends on the virtual tapelibrary for which you are creating the tapes.

3. Click OK to create the specified number of virtual tapes.

Add SAN Clients to Represent Your Backup ServersSAN clients represent the backup servers that have access to the virtual tapelibrary and tapes. There are two types of client, open-access and secure access.

Use the following steps to create a secure-access SAN client.

1. Expand the VTL Servers object in the VTL Console navigation tree, thenexpand the VTL server object representing the nTier VTL appliance.

2. Right-click the SAN Clients object and select Add to launch the Add Clientwizard.

3. Enter the Client Name (hostname or IP address) of the backup server.

Client Type Description

Open-Access Two pre-defined open-access clients, Everyone_iSCSI and Everyone_FC, representany backup server that is zoned with the nTier VTL server. Any backup server canaccess the virtual tape libraries and tapes assigned to these clients.

The Everyone_iSCSI SAN client is the default client on all nTier VTL appliances.If you want to use this client skip to Create Targets for the iSCSI Client to createtargets representing the virtual tape library and drives the client will access.

The Everyone_FC SAN client is available if you purchased the Fibre Channeloption for your nTier VTL appliance. If you want to use this client, skip to Assignthe Virtual Library to a SAN Client .

Secured-Access Secured-access clients represent specific backup servers. These backup servers canonly access the virtual tape library and tapes that are specifically assigned to eachclient.If your nTier VTL server will be shared by multiple backup servers, you can add secure-access iSCSI or Fibre Channel clients to represent each backup server and ensure thateach backup server can access only its own designated virtual tape library and tapedrives.
