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 pane 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.
