5.20 Recovering an Oracle VM Deployment

You can recover an Oracle VM from a snapshot-based backup when severe disaster conditions damage the Oracle VM, or when the server hardware is replaced to such an extent that it amounts to new hardware.

For example, replacing all hard disks leaves no trace of original software on the system. This is similar to replacing the complete system as far as the software is concerned. In addition, it provides a method for disaster recovery of the database servers using an LVM snapshot-based backup taken when the database server was healthy before the disaster condition.

The recovery procedures described in this section do not include backup or recovery of storage servers or the data in an Oracle Database. Oracle recommends testing the backup and recovery procedures on a regular basis.

• Overview of Snapshot-Based Recovery of Database Servers
  The recovery of the Oracle VM consists of a series of tasks.
• Scenario 1: Recovering a Management Domain and Its User Domains from Backup
  You can recover the management domain and all its user domains from a backup.
• Scenario 2: Re-imaging the Management Domain and Restoring User Domains from Backups
  This procedure re-images the management domain and reconstructs all the user domains.
• Scenario 3: Restoring and Recovering User Domains from Snapshot Backups
  Use this procedure to restore lost or damaged files of a user domain using a snapshot-based user domain backup taken from inside a user domain.
