Datafiles
Individual datafiles can be backed up as easily as we can back up a tablespace. If it??™s impractical
to back up an entire tablespace within an RMAN session, you can back up individual datafiles
within a tablespace over a period of days, and the archived redo log files will take care of the rest
during a recovery operation. Here is an example of a datafile backup of a single datafile within a
non-ASM tablespace:
RMAN> backup as backupset datafile
2> '/u04/oradata/ord/oe_trans_06.dbf';
Image Copies
Up until this point, we have been using backupset backups; in contrast, image copies make
bit-for-bit copies of the specified tablespace or entire database.
