Incremental Backups
RMAN incremental backups back up only datafile blocks that have changed since a specified previous backup. You can make incremental backups of databases, individual tablespaces or datafiles.
The goal of an incremental backup is to back up only those data blocks that have changed since a previous backup.
Incremental backups are generally smaller and faster to create than full database backups. Recovery from an incremental backup is faster than recovery using redo logs alone. During a restore from incremental backup, the level 0 backup is used as the starting point, then changed blocks are updated based on level 1 backups where possible to avoid re-applying changes from redo one at a time. Recovering with incremental backups requires no additional effort on your part. If incremental backups are available, RMAN will use them during recovery.
