Deleting a snapshot
Because Storage Mirroring uses the Microsoft
®
Volume Shadow Copy service to create snapshots, the
snapshots can be managed through the Volume Shadow Copy command line administrator. You can
also view, copy, or restore files from the Previous Version tab by accessing the file properties through
a share using Windows Explorer. See your Volume Shadow Copy documentation for details.
Additionally, you can use the Storage Mirroring commands to delete snapshots on the target.
1. View the snapshots on the target by using the snapshot list command.
2. Delete snapshots on the target by using the snapshot delete command.
