NOTE: You can only select one library to unmanage at a time. To unmanage additional libraries, repeat the procedure for each library to unmanage. 4. Select Submit. The Destination Library Details screen displays, with the message, "The library, [library name], was unmanaged successfully." Echo Copy Pool Operations Echo copy acts as a transparent disk cache to the physical library, so that the backup application writes to virtual cartridges in the virtual library. Automigration then automatically schedules the copies from virtual cartridges to their matching physical cartridges (with the same barcodes) based on the automigration policies. For creating echo copies, automigration supports the following backup software on the physical libraries: • CA ARCserve Backup • Commvault Galaxy • HP DataProtector • HP DataProtector Express • Legato Networker • Tivoli Storage Manager • Veritas Net Backup • Veritas Backup Exec CAUTION: Automigration does not support tar formatting. A tar file will not load if the first file on the tape is larger than 1 MB unless you perform a Load for Restore. HP strongly recommends against using automigration with tar-based backup software. After connecting your destination library to the VLS and adding it as a Managed Library, follow these steps to operate echo copy: 1. Identify the Virtual Library you will associate with this managed library. 2. Create an echo copy pool between the virtual library and this managed library. Any cartridges loaded (or already present) in the managed library will be automatically detected, and matching virtual cartridges will be automatically created in the associated virtual library. NOTE: The automatic scanning of new cartridges can take a long time if all the tape drives in the destination library are busy with higher priority operations such as copies. For this reason, it is best to load new tapes when copies are not running. 3. Check for the auto-created virtual cartridges in the virtual library. On the Automigration/Replication tab, expand Source Cartridges in the navigation tree and then select the library of interest. The screen displays the cartridges created by automigration. 4. Any data written to the automigration virtual cartridges will be automatically mirrored onto the matching destination tapes based on the automigration policy settings. Monitor the status of the mirror by using a Command View VLS Console and viewing the destination tapes in Slots in the expanded list under Destination Library. 5. In order to restore from a destination cartridge, either load it into a physical drive that is visible to the backup application, or perform a Load for Restore. Load for Restore copies the destination tape back into the virtual cartridge so that the backup application can then restore from the virtual cartridge. Echo Copy Pool Operations 39

Echo Copy Pool Operations
Echo copy acts as a transparent disk cache to the physical library, so that the backup application
writes to virtual cartridges in the virtual library. Automigration then automatically schedules the
copies from virtual cartridges to their matching physical cartridges (with the same barcodes) based
on the automigration policies.
For creating echo copies, automigration supports the following backup software on the physical
libraries:
•
CA ARCserve Backup
•
Commvault Galaxy
•
HP DataProtector
•
HP DataProtector Express
•
Legato Networker
•
Tivoli Storage Manager
•
Veritas Net Backup
•
Veritas Backup Exec
CAUTION:
Automigration does not support tar formatting. A tar file will not load if the first file
on the tape is larger than 1 MB unless you perform a Load for Restore. HP strongly recommends
against using automigration with tar-based backup software.
After connecting your destination library to the VLS and adding it as a Managed Library, follow
these steps to operate echo copy:
1.
Identify the Virtual Library you will associate with this managed library.
2.
Create an echo copy pool between the virtual library and this managed library.
Any cartridges loaded (or already present) in the managed library will be automatically
detected, and matching virtual cartridges will be automatically created in the associated virtual
library.
NOTE:
The automatic scanning of new cartridges can take a long time if all the tape drives
in the destination library are busy with higher priority operations such as copies. For this
reason, it is best to load new tapes when copies are not running.
3.
Check for the auto-created virtual cartridges in the virtual library. On the
Automigration/Replication
tab, expand
Source Cartridges
in the navigation tree and then
select the library of interest. The screen displays the cartridges created by automigration.
4.
Any data written to the automigration virtual cartridges will be automatically mirrored onto
the matching destination tapes based on the automigration policy settings. Monitor the status
of the mirror by using a Command View VLS Console and viewing the destination tapes in
Slots
in the expanded list under
Destination Library
.
5.
In order to restore from a destination cartridge, either load it into a physical drive that is visible
to the backup application, or perform a Load for Restore. Load for Restore copies the destination
tape back into the virtual cartridge so that the backup application can then restore from the
virtual cartridge.
