To avoid reaching the limit of 255 Snapshot copies per volume, delete your old SnapManager backups when they are no longer needed.
SnapManager provides two ways to delete backups:
- Automatic deletion of older backups in the management group
- Explicit deletion of backups or SnapInfo Snapshot copies only
Note: If a storage group is no longer available in the Exchange server, then backups associated with it can not be removed by the delete backup module .
Attention: Do not use SnapDrive or the storage system administration tools to delete Snapshot copies created by SnapManager. Doing so will leave behind unwanted data that cannot be removed.
