Chapter 6: Restoring Data on CA EVA
The data backed up in a CA EVA backup session can be restored to the application system’s virtual disks using the standard restore
procedure.
6.1 Restoring to the Source Virtual Disks
During restore, the backed up data is restored from the tape device to the source virtual disks, which reside on the local disk array. In a
backup environment with CA EVA, this is the ordinary type of restore that is expected to be used in most cases.
For performance-related considerations, see section “Performance Influences and Implications” on page 13.
6.1.1 Restore Procedure
Depending on the type of data that was backed up (filesystem data or disk image data), the procedure for this type of restore is the same
as standard Data Protector filesystem or disk image restore procedure. For details, refer to HP OpenView Storage Data Protector
EVA/VA/MSA Integration Guide, chapter 3 Snapshot Restore, section Restoring from Backup Media on LAN.
6.2 Restoring to the Destination Virtual Disks
This advanced procedure includes restarting the application system, dismounting the source virtual disks, and performing a planned
failover. The process is not supported by the ZDB for CA EVA extension and has to be performed manually.
