share. (The default name is the original share name.)
3. Click Apply .
The share is recovered on the target system. All data stored on the share at the time the
snapshot was saved is available. The original export protocol of the share (NFS or CIFS)
is retained in the recovery process.
After you recover a share, if you want to continue backing up data to the share,
you must remap your backup application to point to the target system instead of
the source system.
Performing a Failback For a Share
Perform a failback of a NAS share if a source system that was previously unavailable
becomes available again. When you failback a share, you select a received snapshot. The
ETERNUS CS800 copies the snapshot from the target system back to the source system.
You can then perform a recover operation to recreate the share on the source system just as
it was at the point in time when the snapshot was saved.
Before you can failback a share, on the original source system, you must add the
original target system to the list of allowed replication sources (see
"Adding a
Replication Source" on page 278 ). This is because, during failback, the original
target is acting as a source when it sends a snapshot to the original source.
1. To perform a share failback:
On the target system, select a snapshot in the Snapshots List and click Failback .
