Parameters
- DEVclass (Required)
- Specifies the name of the sequential access device class to use.
The device class must be defined in a device configuration file specified by
the DEVCONFIG server option.
If a device configuration file is not available, you can manually create
one. See Administrator's Guide for details.
- VOLumenames (Required)
- Specifies the database backup volume names. If you specify multiple
names, separate them with commas and no intervening spaces.
- Source
- Specifies the source of the database backup volumes named in the
VOLUMENAMES parameter. The default is DBBACKUP. The choices
are:
- DBBackup
- Information about full or incremental database backup volumes will be
displayed.
- DBSnapshot
- Information about snapshot database backup volumes will be
displayed.
Examples

| Date/Time: 05/10/1998 16:45:03 |
| Volume Type: BACKUPFULL |

+--------------------------------------------------------------------------------+
where:
- Date/Time
- The date and time that backup data was recorded on the volume.
- Volume Type
- Whether the backup was full or incremental.
- Backup Series
- The identifying number of the backup series. A backup series is a
full backup and all incremental backups before the next full backup.
- Backup Operation
- The operation number of the backup volume. In a backup series the
full backup is operation 0, the first incremental backup is operation 1, the
second incremental backup is operation 2, and so on.
- Volume Seq
- The sequence, or position, of the volume in the backup series.
Volume sequence 1 identifies the first volume of the first operation (a full
backup), and so on. If a full backup occupies three volumes, the volume
sequence numbers are 1, 2, and 3.
- Device Class
- The name of the device class for the volume.
- Volume Name
- The name of the volume.
