Purpose
Snapshot
Creates a point-in-time view of the production data. The snapshot is not
intended to be an independent copy, but is used to maintain a view of the
production data at the time the snapshot is created.
This preset automatically creates a thin-provisioned target volume with
0% of the capacity allocated at the time of creation. The preset uses a
FlashCopy mapping with 0% background copy so that only data written
to the source or target is copied to the target volume.

Clone
Creates an exact replica of the volume, which can be changed without
affecting the original volume. After the copy operation completes, the
mapping that was created by the preset is automatically deleted.
This preset automatically creates a volume with the same properties as
the source volume and creates a FlashCopy mapping with a background
copy rate of 50. The FlashCopy mapping is configured to automatically
delete itself when the FlashCopy mapping reaches 100% completion.

Backup
Creates a point-in-time replica of the production data. After the copy
completes, the backup view can be refreshed from the production data,
with minimal copying of data from the production volume to the
backup volume.
This preset automatically creates a volume with the same properties as
