Figure 17 Recovery by relocating the Target Appliance
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.
IMPORTANT:
This configuration is possible in only limited situations because it will break any
other backups or replications to the Data Center appliance. In a simple Active-Passive scenario,
however, this may be a very good model.
1.
Transport the appliance from the Data Center to the remote site and reconfigure networking,
etc.
2.
On the Target Appliance (now in the remote site), go to the Replication - NAS Mappings page,
select the Target Share and remove the slot mapping between it and the lost Source Share.
3.
The Target Share becomes a Non-Replicating Share.
NOTE:
If there are other share mappings, do not proceed, this method is not suitable.
4.
Check that the newly non-replicating NAS share has been configured correctly to allow the
required hosts to access it.
5.
Recover data from the NAS share to the host over WAN.
6.
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
.
