Instant Recovery
Chapter 462
Instant Recovery
Refer to the online Help for general information on instant recovery.
You can selectively restore separate writer’s components only if they
reside on separate target volumes. Instant recovery of separate
components also requires that the target volumes with components data
should not contain any other data. If you do not select all writer’s
components residing on the target volumes to be restored, the restore
fails.
Before starting an instant recovery, Application Recovery Manager
checks whether the data that is required for the components restore is
available. If the check fails, the instant recovery session also fails,
ensuring that no data that does not belong to the components is lost.
For Exchange 2007 writer specifics (prerequisites and limitations), see
“Microsoft Exchange Server 2007 Recovery Specifics” on page 58.
Limitations
• The number of replicas available for instant recovery is limited by
Number of replicas rotated, which sets the size of the replica set.
You can view these replicas in the Instant Recovery GUI context by
expanding Restore Sessions. Replicas are identified by the backup
specification name and the session ID. Other information, such as
time when the replica was created, is also provided. Alternately, you
can use CLI to list sessions (see the HP StorageWorks Application
Recovery Manager Command Line Interface Reference for information
about the omnidbvss command).
• Concurrent restores utilizing the same backup system or the same
application system are not supported. Restores utilizing the same
backup system or the same application system must be performed
serially.
• For additional Exchange 2007 writer limitations, see “Microsoft
Exchange Server 2007 Recovery Specifics” on page 58.
