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

7 Restore
Introduction
This chapter describes configuring and running a filesystem or disk image restore of
the data backed up using the XP integration. The sections describe restore procedures
using the Application Recovery Manager GUI and CLI.
The data backed up in a ZDB session is stored on a disk array, or in case you are
using third–party backup software, on backup media.
Instant recovery
Instant recovery restores data directly from a replica to source volumes, without
involving a tape device. All data (whole volume group on UNIX or disk) in the replica
is restored. 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 82) or CLI (see
“Instant recovery using the CLI” on page 84).
Considerations
• When instant recovery starts, Application Recovery Manager disables the
application system. This includes dismounting filesystems and exporting volume
groups (UNIX). Before this is done, filesystems’ and volume groups’ status is
checked, and only mounted filesystems and imported volume groups are
dismounted and exported. At the end of the session, dismounted filesystems are
mounted and exported volume groups are imported to the same mount points as
were used during backup.
• You cannot start several instant recovery sessions using the same disk on the
application system at once. A session can be started only after the preceding
session using the same source volume on the application system finishes
synchronization.
