HP Application Recovery Manager software A.06.10 Concepts guide (March 2008)

Instant recovery
Instant recovery enables you to restore data objects to their states at a particular
point in time. For details of the process, see “Instant recovery” on page 55.
What happens to the replica afterwards depends on the array and the configuration:
• XP: The replica becomes a mirror in synchronization with the recovered source.
You can however configure the instant recovery so that the replica is retained
afterwards.
• EVA: Either the replica becomes the recovered source or the data in the replica
is copied back to the source volume. If the replica becomes the source, it ceases
to exist as a replica. If it is copied back, it can be retained or not (depending on
which option you choose in the GUI).
Deleting replicas
Replicas can be deleted automatically or manually:
• Automatically:
• When a replica becomes the oldest member of a replica rotation set, it is
automatically overwritten (or deleted) when a new replica is created in the
set. You can however exclude replicas from use to protect them. For more
information, see the HP Application Recovery Manager software administrator's
guide.
• A replica can be deleted after instant recovery if configured so. In fact, with
XP array, the replica becomes a mirror in synchronization with the recovered
source. With EVA, the replica becomes the recovered source and so ceases
to exist as a replica, or is copied back to the source volume.
• Manually: When replicas are no longer required within Application Recovery
Manager, you can delete them from the array using the Application Recovery
Manager CLI.
