RC_BACKUP_FILES

This view lists backups known to the RMAN repository as reflected in the recovery catalog. This view corresponds to the V$BACKUP_FILES control file view.

Note:

  • It is usually more convenient to access this information using the LIST BACKUP and LIST COPY commands from within RMAN.

  • You must use DBMS_RCVMAN.SetDatabase to select a database from the recovery catalog schema before you can use this view, even if only one database is registered in the recovery catalog. Oracle Database Backup and Recovery User's Guide explains how to perform this task.

Column Data Type Description
PKEY NUMBER The primary key for the backup.
BACKUP_TYPE VARCHAR2(32) The type of the backup: BACKUP SET, COPY, or PROXY COPY.
FILE_TYPE VARCHAR2(32) Type of the file backed up: DATAFILE, CONTROLFILE, SPFILE, REDO LOG, ARCHIVED LOG, COPY (for an image copy backup) or PIECE (for a backup piece).
KEEP VARCHAR2(3) Whether this backup has KEEP attributes set that override the backup retention policy. Values are YES or NO.
KEEP_UNTIL DATE Date after which this backup is considered obsolete.
KEEP_OPTIONS VARCHAR2(13) Attributes affecting retention for this backup. Possible values are NOLOGS, BACKUP_LOGS, LOGS, and NULL. NOLOGS indicates a consistent backup made when the database was mounted. BACKUP_LOGS indicates that the backup was made in open mode, so archived log backups must be applied to make it consistent. LOGS indicates a long-term backup made with the LOGS keyword, which is now deprecated. NULL indicates that this backup has no KEEP options and becomes obsolete based on the retention policy.
STATUS VARCHAR2(16) Status of the backup. Possible values are: AVAILABLE, UNAVAILABLE, EXPIRED.
FNAME VARCHAR2(1024) Filename of this piece, copy, or filename of the file included in this backup set. For example, for a row whose BACKUP_TYPE is BACKUP SET and FILE_TYPE is DATAFILE, FNAME is the name of the datafile in the backup. On the other hand, if BACKUP_TYPE is BACKUP SET and FILE_TYPE is PIECE, then FNAME shows the name of backup piece.
TAG VARCHAR2(32) The tag for this backup piece or image copy. This column can only have a value if FILE_TYPE is PIECE or COPY.
MEDIA VARCHAR2(80) Media ID for the media on which the backup is stored. This column can only have a value if BACKUP_TYPE is BACKUP SET and FILE_TYPE is PIECE.
RECID NUMBER ID of the control file record corresponding to this row.
STAMP NUMBER Timestamp of the control file record corresponding to this row.
DEVICE_TYPE VARCHAR2(255) Device type on which this backup is stored. This column populated only if FILE_TYPE is PIECE or COPY.
BLOCK_SIZE NUMBER Block size for the backup or copy (in bytes).
COMPLETION_TIME NUMBER Time when this backup was completed. This column populated only if FILE_TYPE is PIECE or COPY.
COMPRESSED VARCHAR2(3) Whether the backup piece represented by this row is compressed. This column populated only if file-type is PIECE (since image copies cannot be compressed, by definition).
OBSOLETE VARCHAR2(3) Whether this backup piece or copy is obsolete. Possible value: YES, NO. This column populated only if FILE_TYPE is PIECE or COPY.
BYTES NUMBER Size of file described by this row. If BACKUP_TYPE is BACKUP SET, this represents the total size of the backup set. If FILE_TYPE is PIECE or COPY, then this represents the size of the individual file. If FILE_TYPE is DATAFILE, ARCHIVED LOG, SPFILE or CONTROL FILE, the value represents how much data was incorporated into the backup set (but note that the corresponding backup set may be smaller, if compression was used in creating the backup set).
BS_KEY NUMBER Backup set key. This column populated only if BACKUP_TYPE is BACKUP SET. Use this column to join with RC_BACKUP_SET or RC_BACKUP_PIECE.
BS_COUNT NUMBER Backup set count. This column populated only if BACKUP_TYPE is BACKUP SET.
BS_STAMP NUMBER Backup set timestamp. This column populated only if BACKUP_TYPE is BACKUP SET.
BS_TYPE VARCHAR2(32) Type of backup set contents (datafiles or archived redo log files). This column populated only if BACKUP_TYPE is BACKUP SET.
BS_INCR_TYPE VARCHAR(32) Backup set incremental type (full or not). This column populated only if BACKUP_TYPE is BACKUP SET.
BS_PIECES NUMBER Number of pieces in backup set. This column populated only if BACKUP_TYPE is BACKUP SET.
BS_COPIES NUMBER Number of copies of this backup set. This column populated only if BACKUP_TYPE is BACKUP SET.
BS_COMPLETION_TIME DATE Completion time of the backup set. This column populated only if BACKUP_TYPE is BACKUP SET.
BS_STATUS VARCHAR2(16) Status of the backup set. Possible values are AVAILABLE, UNAVAILABLE, EXPIRED, or OTHER. (OTHER means that not all pieces of the backup set have the same status, which can happen if some are AVAILABLE and others UNAVAILABLE.) This column populated only if BACKUP_TYPE is BACKUP SET.
BS_BYTES NUMBER Sum of the sizes of all backup pieces in the backup set. This column populated only if BACKUP_TYPE is BACKUP SET.
BS_COMPRESSED VARCHAR2(3) Whether the backup pieces of this backup set are compressed. This column populated only if BACKUP_TYPE is BACKUP SET.
BS_TAG VARCHAR2(1024) Tag or tags of the backup pieces of this backup set. If pieces have different tags, then BS_TAGS will contain a comma-delimited list of all tags for pieces in the backup set. This column populated only if BACKUP_TYPE is BACKUP SET.
BS_DEVICE_TYPE VARCHAR2(255) Type of device on which this backup set is stored. If multiple copies of this backup set exist and are stored on different devices, then this field will contain a comma-delimited list of all device types. For example, for a backup set that is on disk and also backed up on tape, BS_DEVICE_TYPE might contain DISK, SBT_TAPE. This column populated only if BACKUP_TYPE is BACKUP SET.
BP_PIECE# NUMBER Number of backup pieces that make up this backup set. This column populated only if BACKUP_TYPE is BACKUP SET.
BP_COPY# NUMBER Number of copies of this backup set. This column populated only if BACKUP_TYPE is BACKUP SET.
DF_FILE# NUMBER File number of the datafile described by this row. This column populated only if FILE_TYPE is DATAFILE.
DF_TABLESPACE VARCHAR2(30) Tablespace name for the datafile described by this row. This column populated only if FILE_TYPE is DATAFILE.
DF_RESETLOGS_CHANGE# NUMBER RESETLOGS change of the datafile described by this row. This column populated only if FILE_TYPE is DATAFILE.
DF_CREATION_CHANGE# NUMBER Creation change number of the datafile described by this row. This column populated only if FILE_TYPE is CONTROLFILE,DATAFILE or SPFILE.
DF_CHECKPOINT_CHANGE# NUMBER Checkpoint change number of the datafile described by this row. This column populated only if FILE_TYPE is CONTROLFILE,DATAFILE or SPFILE.
DF_CKP_MOD_TIME DATE Checkpoint time of the datafile described by this row. Valid only if FILE_TYPE is CONTROLFILE,DATAFILE or SPFILE.
RL_THREAD# NUMBER Redo log thread number of the archived redo log described by this row. Valid only if FILE_TYPE is ARCHIVED LOG.
RL_SEQUENCE# NUMBER Redo log sequence number of the archived redo log described by this row. Valid only if FILE_TYPE is ARCHIVED LOG.
RL_RESETLOGS_CHANGE# NUMBER RESETLOGS change number of the archived redo log described by this row. Valid only if FILE_TYPE is ARCHIVED LOG.
RL_FIRST_CHANGE# NUMBER First change number in the archived redo log described by this row. Valid only if FILE_TYPE is ARCHIVED LOG.
RL_FIRST_TIME DATE Time of the first change in the archived redo log described by this row. Valid only if FILE_TYPE is ARCHIVED LOG.
RL_NEXT_CHANGE# NUMBER Change number after the archived log described by this row. Valid only if FILE_TYPE is ARCHIVED LOG.
RL_NEXT_TIME DATE Time of the first change after the archived log described by this row. Valid only if FILE_TYPE is ARCHIVED LOG.
