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, 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 retention policy. Values are YES or NO.

KEEP_UNTIL

DATE

Date after which this backup will be considered obsolete.

KEEP_OPTIONS

VARCHAR2(13)

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 row with 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. (Valid only if FILE_TYPE is PIECE or COPY.)

MEDIA

VARCHAR2(80)

Media ID for the media on which the backup is stored. Valid only if BACKUP_TYPE is "BACKUP SET" and FILE_TYPE is "PIECE".

RECID

NUMBER

Recidof 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. Valid 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. Valid only if FILE_TYPE is PIECE or COPY

COMPRESSED

VARCHAR2(3)

Whether the backup piece represented by this row is compressed. Valid 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Whether this backup piece or copy is obsolete.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. Valid only if FILE_TYPE is PIECE or COPY

BYTES

NUMBER

Size of file described by this row. If FILE_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_BYTES

NUMBER

Sum of the sizes of all backup pieces in the backup set. Valid only if FILE_TYPE is BACKUP SET.

BS_COMPRESSED

VARCHAR2(3)

Whether the backup pieces of this backup set are compressed. Valid only if FILE_TYPE is BACKUP SET.

BS_TAG

VARCHAR2(1024)

Tag or tags of the backup pieces of this backup set. If pieces have different tags, BS_TAGS will contain a comma-separated list of all tags for pieces in the backup set. Valid only if FILE_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, this field will contain a comma-separated 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".
