2.11 Recovering Oracle Linux Database Servers Using a Snapshot-Based Backup

You can recover a database server file systems running Oracle Linux using a snapshot-based backup after severe disaster conditions happen for the database server, 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 within the Oracle databases. Oracle recommends testing the backup and recovery procedures on a regular basis.
