Expire and synchronize the backup catalogs
ON-Bar maintains a history of backup and restore operations in the sysutils database and an extra copy of the backup history in the emergency boot file. ON-Bar uses the sysutils database in a warm restore when only a portion of the data is lost. ON-Bar uses the emergency boot file in a cold restore because the sysutils database cannot be accessed. You can use the onsmsync utility to regenerate the emergency boot file and expire old backups.
- Backups that the storage manager has expired
- Old backups based on the age of backup
- Old backups based on the number of times they have been backed up
Use onsmsync with the database server online or in quiescent mode to synchronize both the sysutils database and the emergency boot file.
- Bring the database server online or to quiescent mode.
- Run the onsmsync utility without any options.
- Adds backup history to sysutils that is in the emergency boot file but is missing from the sysutils database.
- Removes the records of restores, whole-system restores, fake backups, successful and failed backups from the sysutils database.
- Expires old logical logs that are no longer needed.
- Regenerates the emergency boot file from the sysutils database.
