IBM Tivoli Storage Manager for Mail, Data Protection for Microsoft Exchange Server, Version 7.1

Delete backup command

To delete a VSS backup of an Exchange Server database, use the delete backup command.

You must have local registry rights for all versions of Exchange Server to complete a Data Protection for Microsoft Exchange delete backup. When a full VSS snapshot backup is completed, the backup remains active until the backup version is deleted with the delete backup command, or expired by VSS according to the defined policy. Two different active backups can exist at the same time:

Full backup, along with any associated incremental backups and differential backups.
Copy backup, along with any associated incremental backups and differential backups.

When you delete an active full or copy backup, the state of the previous active full or copy backup changes from inactive to active. However, the current active incremental or differential backup is not deleted. The backup erroneously seems to be associated with the newly active full or copy backup. Also, the incremental or differential backup (associated with the previous inactive full or copy backup that changed to active) remains inactive. This inactive incremental or differential backup might not display in the query output unless the /all parameter is specified with the query fcm command.
