8.92 V$BACKUP_FILES

V$BACKUP_FILES displays information about all RMAN backups (both image copies and backup sets) and archived logs.

This view simulates the LIST BACKUP and LIST COPY RMAN commands. This view requires that the database be set using the DBMS_RCVMAN.SETDATABASE procedure.

Column Datatype Description

PKEY

NUMBER

Primary key for the backup

BACKUP_TYPE

VARCHAR2(32)

Type of the backup:

  • BACKUP SET

  • COPY

  • PROXY COPY

FILE_TYPE

VARCHAR2(32)

Type of the file:

  • DATAFILE

  • CONTROLFILE

  • SPFILE

  • REDO LOG

  • ARCHIVED LOG

  • COPY (for an image copy backup)

  • PIECE (for a backup piece)

KEEP

VARCHAR2(3)

Indicates whether the backup has a retention policy different from the value for CONFIGURE RETENTION POLICY (YES) or not (NO)

KEEP_UNTIL

DATE

If the KEEP UNTIL TIME clause of the BACKUP command was specified, then this column shows the date after which the backup becomes obsolete. If the column is null and KEEP_OPTIONS is not null, the backup never becomes obsolete.

KEEP_OPTIONS

VARCHAR2(13)

KEEP options for the backup:

  • LOGS - RMAN keeps the logs needed to recover the backup
