Figure 7 Recovery by promoting a Target Share over NAS

Before the failure a mapping existed between a Source Share on the remote site StoreOnce Backup
System and a Target Share on the Data Center StoreOnce Backup System. After the failure the
mapping still exists but the Source Share is missing. The Target Share on the Data Center StoreOnce
Backup System is still in Target Share mode, it has not had its mappings removed.
1.

On the Target Appliance in the Data Center, go to the

Replication - NAS Mappings

page,

select the Target Share and remove the mapping between it and the lost Source Share.

2.

The Target Share becomes a Non-Replicating Share.

3.

Make sure the backup application is targeting the newly non-replicating share and recover
the data.

4.

At this point there is no HP StoreOnce Source Appliance at the remote site. If one is installed
at a later date, you can reverse recover the data and configure replication, as described in

Reverse replication using the wizard (page 115)
