Defining a backup strategy for Oracle databases

Defining a backup strategy before you create your backup jobs ensures that you have the backups that you require to successfully restore or clone your databases. Your service-level agreement (SLA), recovery time objective (RTO), and recovery point objective (RPO) largely determine your backup strategy.

About this task

An SLA defines the level of service that is expected and addresses many service-related issues, including the availability and performance of the service. RTO is the time by which a business process must be restored after a disruption in service. RPO defines the strategy for the age of the files that must be recovered from backup storage for regular operations to resume after a failure. SLA, RTO, and RPO contribute to the data protection strategy.

Perform the following steps for each of your databases.

Steps

  1. Determine the supported database configurations.
  2. Decide the type of backup that you require.
  3. Decide on which node in a RAC environment you want to create your backup.
  4. Determine when you should back up your databases.
  5. Decide how to name your backups.
  6. Decide if you want to catalog or uncatalog your backups.
  7. Determine the retention period for the Snapshot copies on the source storage system and the SnapMirror destination.
    SnapMirror retention is implicitly defined based on the Snapshot copy retention of the primary storage. SnapVault retention has to be defined explicitly on the ONTAP storage system.
  8. Decide whether you want to verify the backup copies using the primary or secondary storage volume.
  9. Determine the supported prescripts and postscripts.
  10. Decide whether you want to use NetApp SnapMirror technology for replication or NetApp SnapVault technology for long term retention.
