11.3 Receive NAS
To recover a share:
1. On the target system, select a snapshot in the Snapshots List and click Recover .
The Recovered Share Name page displays (see "Recovered Share Name Page" on page
359 ).
Figure 248: Recovered Share Name Page
2. (Optional) In the Recovered Share Name box, type a new name for the recovered
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/SMB) 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 259 ). This is because, during failback, the original
target is acting as a source when it sends a snapshot to the original source.
