9 Restore processes with replication
In this chapter:
• Recovering a source appliance, VTL devices
• Recovering a source appliance, NAS shares
Recovering a Source Appliance (Virtual Tape devices)
:
If you replace the disks in the source StoreOnce Backup System and keep the original appliance,
the source to target mapping will still exist on the repaired StoreOnce Backup System. You MUST
break this mapping BEFORE carrying out recovery. If you do not, the now blank Source Library
(on the replacement disks) will overwrite the data on the Target Library. You will effectively lose
backup data on both Source and Target Libraries.
Reverse replication using the wizard
The remote site has lost both the host servers and the StoreOnce system. New hardware has been
purchased and installed and the administrator now wants to recover data to the StoreOnce Backup
System and then restore to the host server. Before the failure a mapping existed between a Source
Library on the remote site StoreOnce Backup System and a Target Library on the Data Center
StoreOnce Backup System. After the failure the Source Library is missing; the mapping may or
may not still exist.
Figure 7 Recovery using reverse replication
1. Create a new Non-Replicating Library on the Source Appliance (either by running the Installation
wizard or by using the Devices page).
2. Go to the Replication - Virtual Tape Mappings page and select the new non-replicating library.
3. Click Start Recovery Wizard.
