RMAN Commands
RMAN Commands : =============== An incremental backup: ======================= stores only blocks changed since a previous backup. Thus, they provide more compact backups and faster recovery, thereby reducing the need to apply redo during data file media recovery. If you enable block change tracking, then you can improve performance by avoiding full scans of every input data file. You use the BACKUP INCREMENTAL command to perform incremental backups. cumulative incremental backup ============================== A level 1 backup can be a cumulative incremental backup, which includes all blocks changed since the most recent level 0 backup, or a differential incremental backup, which includes only blocks changed since the most recent incremental backup. BACKUP INCREMENTAL LEVEL 1 CUMULATIVE DATABASE; You can use the VALIDATE command to confirm that all database files exist, are in their correct location, and are free of physical corr...
