HP Application Recovery Manager software A.06.10 Administrator's guide (March 2008)

3 Restore
Introduction
This chapter describes configuring and running a filesystem or disk image restore of
the data backed up using the EVA integration. The sections describe restore
procedures using the Application Recovery Manager GUI and CLI.
Instant recovery
Instant recovery restores data directly from a replica to source volumes. All data in
the replica is restored, including filesystems or other objects which were not explicitly
selected for backup. For instant recovery concepts, see the HP Application Recovery
Manager software concepts guide.
You can perform instant recovery using Application Recovery Manager GUI (see
“Instant recovery using the GUI” on page 49) or CLI (see
“Instant recovery using the CLI” on page 52).
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 omnidbsmis man page for information).
When instant recovery starts, Application Recovery Manager disables the application
system. This includes dismounting filesystems and deactivating or exporting volume
groups (UNIX). Before this is done, filesystems’ and volume groups’ status is checked,
and only mounted filesystems are dismounted and active volume groups are
deactivated or exported. At the end of the session, volume groups are reactivated
and dismounted filesystems are mounted to the same mount points as were used
during backup.
