Overview of Protected Database Backup Settings
Before you back up a protected database to Recovery Appliance, you must configure the protected database backup settings. These settings, described in Table 3-2, define the default behavior for your protected database backup environment. RMAN assigns default values for each backup setting. However, it is recommended that you configure settings according to the backup requirements of the protected database.
Table 3-2 Protected Database Backup Settings
| Backup Setting | Description |
|---|---|
|
Control file autobackup |
Specifies that the control file and server parameter file must be automatically backed up whenever a backup record is added or database structure metadata in the control file changes. |
|
Disk backup location |
When configuring backups for the Recovery Appliance, if backup polling is required, then specify the backup polling location. |
|
Backup optimization |
Skips the backup of files when an identical file has already been backed up to the Recovery Appliance. |
|
Retention policy |
Specifies which backups must be retained to meet your recovery goals. You can either specify a recovery window or a redundancy value. This setting needs to be specified when you use a parallel backup strategy and need to delete obsolete backups created by your existing (not Recovery Appliance) backup strategy. |
|
Archived redo log deletion policy |
Specifies when archived redo logs are eligible for deletion. This policy applies to all archiving destinations including the fast recovery area. |
