Volume Copy from a Master Volume
Master Volume Transient Snapshot
1. Volume copy request is made with a master volume as the source.
2. A new volume is created for the volume copy, and a hidden, transient snapshot is created.
3. Data is transferred from the transient snapshot to the new volume.
4. On completion, the transient volume is deleted and the new volume is a completely
independent copy of the master volume, representing the data that was present when the
volume copy was started.
Volume Copy from a Snapshot
Master Volume Snapshot(s)
1. A master volume exists with one or more snapshots associated with it. Snapshots can be in
their original state or they can be modified.
2. You can select any snapshot to copy, and you can specify that the modified or unmodified data be
copied.
3. On completion, the new volume is a completely independent copy of the snapshot. The snapshot
still remains, though you can choose to delete it.
