Cumulative Vs Differential Backup Rman at Amelia Rojas blog

Cumulative Vs Differential Backup Rman. A cumulative incremental backup, which backs up all changed blocks after the most recent incremental backup at level 0. Cumulative incremental backups reduce the work needed for a restore operation by ensuring that you only need one incremental backup from any particular level. A cumulative incremental backup, backs up all the blocks that have changed after the most recent incremental backup at level 0 only. It is the most common kind of incremental backup which protects all the blocks that have changed in the last incremental backup, at either level 1 or 0. Cumulative incremental is more efficient in terms of restore where ti’s require only one incremental backup from any particular level so it reduces the workload. Cumulative backups copy all blocks that have changed since the last full backup, as well as any blocks changed since the last. This reduces the work needed when recovering after a restore as only the desired level 1 is required to be applied instead of several level 1 in sequence. In a cumulative level 1 backup, rman backs up all the blocks used since the most recent level 0 incremental backup. In a differential level 1 backup, rman backs up all blocks that have changed since the most recent cumulative or differental incremental. Cumulative backups require more storage space than differential backups, but they are preferable during a restore operation because only one.
