Delete backup command

Use the delete backup command to delete a VSS backup of an Exchange Server database.

You must have local registry rights (for all versions of Exchange Server) to run a Tivoli® Storage FlashCopy® Manager for Exchange Server delete backup.

  • When you run full VSS snapshot backup, the backup remains active until the backup version is either deleted with the delete backup command, or expired by Tivoli Storage FlashCopy Manager according to the defined policy. The expiration does not delete an incremental backup. 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 and 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 is now 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.
  • If you delete multiple LOCAL snapshots that are stored on SAN Volume Controller, Storwize® V7000, or Space Efficient volumes, you must do so in the same order in which you created the snapshots. That is, you must delete the oldest one first, followed by the second oldest. Failure to delete them in this order can cause removal of other snapshots of the same source.
