Oracle documentation says "Incremental backups capture on a block-by-block basis changes in your database since a previous incremental backup".
I created level 0 backup
RMAN> backup incremental level 0 tablespace users;
Now after creating the level 0 backup, i created the level 1 backup
RMAN> backup incremental level 1 tablespace users;
RMAN successfully created level 1 backup, creating a file in flash_recovery_area.
I executed the above two RMAN command simultaneously. During this time, nothing changed in the database. So what exactly the new level 1 backup contains? As none of the blocks are changed.
