You should execute following level 0 backup on sunday. When the database crashed on wednesday, firstly full backup is restored which is taken on the sunday and than each incremental backups are restored which is taken every day.Ī sample Incremental backup script is as follows. Second incremental backup is changed blocks of the first incremental backup. The incremental backup is the backup of the changed blocks and the first incremental backup is the backup of the blocks after the full backup.

A full backup is taken on the weekend, and after that the incremental backups are taken every day on the weekday. Here is a sample incremental backup scenario.

When the level = 0, the full backup of the database is taken, and when level = 1, the backups are taken after first level = 0 backup of the changed blocks. RMAN has two level option for incremental backup. In order to take a incremental backup, you must have a full backup associated with this backup. Second incremental backups after the first incremental backup will take the backup of the changed blocks after the previous first incremental backup. Incremental Backup: This type of backup refers to the Backup of the changed Block after the last full backup.
