To recover a replicated share or partition:
1. On the target system, select a received snapshot and perform a recover operation (see
"Recovering a Share" on page 359 or "Recovering a Partition" on page 373).
The share or partition is now available on the target system.
2. (Optional) Map your backup application to the recovered share or partition on the target
system to continue making backups.
3. When the source system is operating correctly again, choose one of the following
actions:
● Failback the share or partition to restore it on the original source system (see "Task
Overview: Performing a Share or Partition Failback" on page 347). Then, if
necessary, map your backup application to the restored share or partition on the
original source system.
● Continue to make backups to the recovered share or partition on the original target
system. In addition, set up replication to replicate the share or partition back to the
original source system (see "Task Overview: Setting Up and Performing Repli-
cation" on page 344). In this scenario, the original source system is now the target,
and the original target system is now the source.
Task Overview: Performing a Share or Partition Failback
If a NAS share or VTL partition is lost or damaged on the source system, you can failback
the share or partition to the source system using a received snapshot on the target system.
When you failback a share or partition, it is restored on the source system just as it was at
the point in time when the snapshot was saved.
To perform a share or partition failback:
1. On the original source system, add the original target system to the list of allowed repli-
cation sources (see "Adding a Replication Source" on page 239).
I
For the purposes of failback, the original source system is now acting as a target
because it will receive the snapshot from the original target system.
2. On the original target system, select a received snapshot and perform a failback
operation pointing to the original source system, and then recover the share or partition
on the original source system (see "Performing a Failback for a Share" on page 360 or
"Performing a Failback for a Partition" on page 375).
The share or partition is now available on the original source system.
3. (Optional) If necessary, map your backup application to the restored share or partition
on the original source system.
