Creating a Reset Snapshot Task
You can create a task to reset a snapshot, which deletes the data in the snapshot and
resets it to the current data in the associated master volume. The snapshot's name
and other volume characteristics are not changed.
Caution – Before scheduling a reset snapshot task, consider that if the snapshot is
mounted to a host operating system, the snapshot must be unmounted before the
reset is performed; leaving it mounted can cause data corruption.
To create a task to reset a snapshot:
1. Select Manage > Scheduler > Manage Scheduler.
2. In the Tasks panel click Add New Task.
The Create Task panel is displayed.
3. Select Reset Snapshot.
4. Select a snapshot volume to reset.
