.. -*- rst -*- Share snapshots =============== Use the Shared File Systems 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. The APIs below allow controlling share snapshots. They are represented by a "snapshot" resource in the Shared File Systems service, and they can have user-defined metadata such as a name and description. 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.yaml`` file to grant permissions for these actions to other roles. List share snapshots ~~~~~~~~~~~~~~~~~~~~ .. rest_method:: GET /v2/snapshots Lists all share snapshots.
