ANR4550I Full database backup (process 15) complete, 2002 pages copied. ANR0985I Process 15 for DATABASE BACKUP running in the FOREGROUND completed with completion state SUCCESS at 11:40:08. The output from the two examples is very similar because the snapshot was run immediately after the full backup. Tip: The devclass parameter may have a different value for your installation. You can run the query devclass format=detailed command to check the available device classes and query library to check the corresponding libraries available for use. You can run the backup db command at any time, without having to stop the server. Tip: We recommend sending the most up-to-date Tivoli Storage Manager database backup off-site, to form a recovery position for your Tivoli Storage Manager environment. Although our book material uses the full and incremental features to handle Tivoli Storage Manager database backups, you should consider also running a DBSNAPSHOT as well. Keep the full and incremental database backups onsite for faster recovery. The DBSNAPSHOT backup, being an out-of-band backup and not dependent on any incremental backups, should be taken off-site with any other off-site tapes. 5.9 Additional commands This section details some extra commands that relate to the Tivoli Storage Manager database. 5.9.1 DELETE VOLHIST TYPE=DBBACKUP If you are using the Disaster Recovery Manager (DRM), your database backups will be managed and expired automatically. You do not need to delete volume history. However, if you are not using DRM, you need to manually delete database backup volume history after a period of time. A common problem reported by new Tivoli Storage Administrators is running out of tapes. It turns out that many tapes have been used by old server database backups, and they have never been expired. The problem can be compounded by the fact that each database backup requires its own tape-it is not possible to "stack" multiple backups onto a single tape. 212 IBM Tivoli Storage Manager Implementation Guide
