Backing Up Database

To back up an Tivoli Storage Manager database to sequential access storage volumes, first complete the following fields and then click Finish, or click Cancel to end the task.

Device Class

Select the name of the sequential access device class to use for the backup. You cannot use a device class with a device type of NAS.

Type

Select an option for the type of backup to run.
 
Incremental Specifies that you want to run an incremental backup of the Tivoli Storage Manager database. The maximum number of incremental backups you can run between full backups is 32. You can run an incremental backup whenever a full backup is not required. The default is Incremental.
Full Specifies that you want to run a full backup of the Tivoli Storage Manager database. A full backup is required when any of the following conditions are true: 
  • The database has never been backed up. 
  • The maximum number of incremental backups allowed between full backups has been reached. 
  • The log mode was changed from NORMAL to ROLLFORWARD. 
  • The database was extended or reduced. Each full backup, whether run automatically by Tivoli Storage Manager based on the settings you specify with the DEFINE DBBACKUPTRIGGER command or run by issuing the BACKUP DB command, resets the count for incremental backups to 0. 
  • The database has been restored using a salvage dump created with the DSMSERV DUMPDB command and has not been backed up since it was restored.
Dbsnapshot Specifies that you want to run a full snapshot backup of the Tivoli Storage Manager database, but you do not want to interrupt the current full/incremental backup series.

Volume Names

Enter the volume names Tivoli Storage Manager will use to backup the database. You can type the name of a file that contains a list of volumes used to backup the database. In the file, each volume name must be on a separate line. Blank lines and comments lines that begin with an asterisk are ignored.

Example: To use volumes TAPE01, TAPE02, and TAPE03, create a file named TAPEVOL that contains these lines:

TAPE01
TAPE02
TAPE03

You can then specify the volumes for the command as follows: FILE:TAPEVOL.

Use Scratch Volumes

Specify whether to use scratch volumes for the backup.
 
Yes Specifies that scratch volumes can be used only if not enough space is available to store the backup data on the specified volumes. The default is Yes.
No Specifies that scratch volumes cannot be used. If there is not enough space to store the backup data on the specified volumes, the backup will fail.

Wait for Completion

Specify whether to wait for the server to complete processing this command in the foreground.
 
Yes Specifies that the server processes this command in the foreground. If you select Yes, you wait for the command to complete before continuing with other tasks. 
No Specifies that the server processes this command in the background. If you select No, you can continue with other tasks while the command is being processed. The default is No.
