VTree may be used as a source volume of a policy (any policy). For more information
on V-Trees, see "Snapshots" in the Getting to Know Guide .

auto-snapshots. Snapshots created by the policy are referred to as auto-snapshots.

If the source volume has no auto snapshots, it doesn't matter if you select Detach

choose to detach all snapshots. They become regular snapshots as if the user
created them manually. If you select Remove auto snapshots, they are deleted.
