You can perform a selective online incremental backup on the following databases:
- Oracle
You perform a selective online incremental backup when the database is online and have already performed a selective online full backup. A selective online incremental subclient includes the data, logs and control file. It uses fewer resources because it only contains the changes from the last selective online full or selective online incremental backup. A selective online incremental backup is self-contained because the data and logs reside on the same media. You can use this backup in a disaster recovery, because you do not need to locate different offsite media from multiple jobs to recover the database.
The data and logs age together.
A selective online incremental full backup is part of a backup cycle that contains one selective online full backup and one or more selective online incremental backups
The following rules apply to selective online incremental backups:
-
The selective online incremental backup job waits for currently running jobs on the same instance to complete before it starts.
-
You can configure different storage policies for the data and archive logs. Selective online incremental backups use the log storage policy that you defined on the instance.
-
If the data stream number that you define at the subclient level is less than the archive log stream number that you define at the instance level, the backup uses the subclient data stream number. The selective online incremental backup ignores the instance level log stream number for the archive logs.
-
You cannot restart or preempt selective online incremental backups.
-
You cannot restart or preempt log backups that you submit during the selective online incremental backup data phase.
-
You can only run CommCell Console archive log backups during the data backup phase of the selective online incremental job.
-
You cannot run command line archive log backups during the data backup phase of the selective online incremental job.
-
No other data or log backup jobs can run on the same instance during the backup log phase.
Retention Rules for Selective Online Incremental Backups
The selective online incremental backup follows the retention rules for the selective online full backup that it is associated with. For more information on selection online full backup retention rules, see Selective Online Full Backups.
