11 Restore processes without replication In this chapter: • Restore scenarios • Restoring single files • Restore and deduplication • Reconnecting toto iSCSI VTL devices after host failure NOTE: If you are using replication, there are other options for restoring data. Restore scenarios There are three main restore scenarios. Basic file restore This is carried out from the HP StoreOnce Backup System. Use the backup application to restore files from the HP StoreOnce Backup Systemto the host, as required. Restore after host failure This is carried out from the HP StoreOnce Backup System. 1. Rebuild the host operating systems and install applications then reconnect to the HP StoreOnce Backup System. 2. Use the backup application to restore data files from the HP StoreOnce Backup System to the host. Bare Metal Disaster Recovery (NAS Shares) NOTE: Bare Metal Disaster Recovery may be possible in some cases with Fibre Channel VTL, if the backup application supports Fibre Channel connectivity through the recovery process. iSCSI VTL recovery in this way is not possible with current backup applications. If your backup application supports Bare Metal Disaster Recovery, you can use it create a boot recovery CD. 1. Use the boot recovery CD to boot the host system into your backup application's recovery console and reconnect to the HP StoreOnce Backup System. Backup System user guide 137

11 Restore processes without replication
In this chapter:
•
Restore scenarios
•
Restoring single files
•
Restore and deduplication
•
Reconnecting toto iSCSI VTL devices after host failure
NOTE:
If you are using replication, there are other options for restoring data.
Restore scenarios
There are three main restore scenarios.
Basic file restore
This is carried out from the HP StoreOnce Backup System. Use the backup application to restore files
from the HP StoreOnce Backup Systemto the host, as required.
Restore after host failure
This is carried out from the HP StoreOnce Backup System.
1.
Rebuild the host operating systems and install applications then reconnect to the HP StoreOnce
Backup System.
2.
Use the backup application to restore data files from the HP StoreOnce Backup System to the
host.
Bare Metal Disaster Recovery (NAS Shares)
NOTE:
Bare Metal Disaster Recovery may be possible in some cases with Fibre Channel VTL, if the backup
application supports Fibre Channel connectivity through the recovery process. iSCSI VTL recovery in
this way is not possible with current backup applications.
If your backup application supports Bare Metal Disaster Recovery, you can use it create a boot
recovery CD.
1.
Use the boot recovery CD to boot the host system into your backup application's recovery console
and reconnect to the HP StoreOnce Backup System.
