============================================
Consistency group snapshots (since API v2.4)
============================================
You can create snapshots of consistency groups. To create a
snapshot, you specify the ID of the consistency group that you want
to snapshot. After you create a consistency group snapshot, you can
create a consistency group from it.
A consistency group snapshot can have member shares. To add a
member share, include the ``consistency_group_id`` parameter in the
create share request. This ID must match the ID of the consistency
group from which the consistency group snapshot was created. Then,
when you use consistency group snapshots to restore data, you can
easily determine which shares belong to a consistency group.
As an administrator, you can also reset the state of a consistency
group snapshot and force-delete a consistency group snapshot in any
state. Use the ``policy.json`` file to grant permissions for these
actions to other roles.
