==================
Consistency groups
==================

Consistency groups enable you to create snapshots at the exact same
point in time from multiple volumes. For example, a database might
place its tables, logs, and configuration on separate volumes. To
restore this database from a previous point in time, it makes sense
to restore the logs, tables, and configuration together from the
exact same point in time.

Use the ``policy.json`` file to grant permissions for these actions
to limit roles.
