Defining the Database Backup Trigger

To define settings for the database backup trigger, complete the following fields and then click Finish, or click Cancel to end the task. The database backup trigger determines when Tivoli Storage Manager automatically runs a full or incremental backup of the Tivoli Storage Manager database and deletes any unnecessary recovery log records.

Full Device Class

Select the name of the sequential access device class to use for full backups.

Log Full Percentage

Enter the percentage value of 1 to 99 when Tivoli Storage Manager automatically backs up the database, based on the percentage of available space used for the recovery log. When the percentage of space used for the recovery log exceeds this value, Tivoli Storage Manager performs an automatic backup of the database and removes unnecessary records from the recovery log. The default is 50.

Incremental Device Class

Select the name of the sequential access device class to use for incremental backups.

Incrementals Between Fulls

Enter the maximum number of incremental backups that can be run before a full backup is required. You can specify a value from 0-32. 0 specifies that Tivoli Storage Manager runs only full backups automatically. The default is 6.
