BACKUP

Processes files output by the BACKUP command.

WithCHANGE BACKUP:

Specify one or more objects using the "CHANGE BACKUP OF listObjList" form of the command. Otherwise, CHANGE BACKUP operates on all backup sets, image copies, and proxy copies recorded in the repository.

With CROSSCHECK BACKUP:

If you are running CROSSCHECK BACKUP, then the command crosschecks BACKUP output that has status AVAILABLE or EXPIRED: backup sets (including backup pieces), proxy copies, and image copies. RMAN crosschecks all backups not marked UNAVAILABLE, even if they cannot be restored or if they are incremental backups whose parent full backup or copy no longer exists.

Specify one or more objects using the "CROSSCHECK BACKUP OF listObjList" form of the command. Otherwise, RMAN crosschecks backups of the whole database.

With DELETE BACKUP:

Deletes backup sets and proxy copies.

Specify one or more objects using the "DELETE BACKUP OF listObjList" form of the command. Otherwise, RMAN deletes backup sets of the whole database.

BACKUPSET

When followed by a list of primary keys: this is actually a case of the recordSpec syntax element in the syntax diagram for maintSpec. In such a case, the keys identify backupsets for use with the CHANGE, CROSSCHECK and DELETE commands. For more details, see "recordSpec" and "LIST Output" for an explanation of the column headings of the LIST output tables. Use the KEY column of the output to obtain the primary key usable in the CHANGE and DELETE commands.

When not followed by a list of primary keys: A synonym for BACKUP.

COPY

Processes datafile copies, control file copies, archived redo logs, and image copies of archived redo logs.

If you do not specify an option for CHANGE COPY, then the command operates on all image copies recorded in the repository.

If you are running CROSSCHECK COPY, then by default the command checks all image copies of all files in the database with status AVAILABLE or EXPIRED.

By default, DELETE COPY removes copies of all files in the database. Specify the EXPIRED option to remove only copies that are marked EXPIRED in the repository.

Restricts the list of objects operated on to the object type specified in the listObjList clause. If you do not specify an object, then the command defaults to all copies. Note that CHANGE COPY OF DATABASE includes datafiles but not control files.

archivelogRecordSpecifier

Processes the specified archived redo logs.

See Also: "archivelogRecordSpecifier"

Restricts the command based on the specified options.

recordSpec

Specifies the file that you are performing maintenance on. See "recordSpec".

Allocates automatic channels for the specified device type only. This option is valid only if you have configured automatic channels and have not manually allocated channels. For example, if you configure automatic disk and tape channels and run CROSSCHECK ... DEVICE TYPE DISK, then RMAN allocates only disk channels.
