Share snapshots
===============
Use the shared file service to make snapshots of shares. A share
snapshot is a point-in-time, read-only copy of the data that is
contained in a share. You can create, manage, update, and delete
share snapshots. After you create or manage a share snapshot, you
can create a share from it. You can also revert a share to its most
recent snapshot.
You can update a share snapshot to rename it, change its
description, or update its state to one of these supported states:
- ``available``
- ``error``
- ``creating``
- ``deleting``
- ``error_deleting``
- ``manage_starting``
- ``manage_error``
- ``unmanage_starting``
- ``unmanage_error``
- ``restoring``
As administrator, you can also reset the state of a snapshot and
force-delete a share snapshot in any state. Use the ``policy.json``
file to grant permissions for these actions to other roles.
