Deleting snapshot backups

IBM® Storage Protect Snapshot snapshot backups can be deleted from the snapshot repository.

Before you begin

Optionally, you can delete snapshot backups on DS8000® and SAN Volume Controller storage subsystems that contain a dedicated set of target volumes in one or more target sets. With IBM XIV® Storage System solutions you can create as many snapshot backups as needed, and old backups are manually deleted. Old backups can also be deleted automatically by using the MAX_VERSIONS (MAX_SNAPSHOT_VERSIONS) parameter.

About this task

Manually delete an IBM Storage Protect Snapshot snapshot backup by following the procedure.

Procedure

Run the following command to unmount the file systems and export the volume groups on a backup system. This method is used when the backup that is using this target set is currently mounted. This step can be omitted if the backup is not currently mounted.

fcmcli -f unmount [-B <backupID>]
Based on the use of this target set, any existing source, and target snapshot relationships (such as INCR or NOCOPY) must be withdrawn. Run the following command:

db2acsutil delete

Results

Note: For IBM XIV Storage System, these commands delete the snapshot backup in the IBM Storage Protect Snapshot snapshot repository, and the snapshot on the storage system is also deleted.

Note: (DS8000 or SAN Volume Controller): These commands delete the snapshot backup in the IBM Storage Protect Snapshot snapshot repository only. The source and target relations on DS8000 or SAN Volume Controller are not withdrawn.
