Snapshot Support
~~~~~~~~~~~~~~~~
Snapshot support is disabled by default, so in order to allow shapshots for a
share type, the ``snapshot_support`` extra spec must be set to True.
Creating a share from a snapshot is also disabled by default so
``create_share_from_snapshot_support`` must also be set to True if this
functionality is required.
For a new share type:
.. code-block:: console
$ manila type-create --snapshot_support True \
--create_share_from_snapshot_support True \
${share_type_name} True
For an existing share type:
.. code-block:: console
$ manila type-key ${share_type_name} \
set snapshot_support=True
$ manila type-key ${share_type_name} \
set create_share_from_snapshot_support=True
To create a snapshot from a share where snapshot_support=True:
.. code-block:: console
$ manila snapshot-create ${source_share_name} --name ${target_snapshot_name}
To create a target share from a shapshot where create_share_from_snapshot_support=True:
.. code-block:: console
$ manila create cifs 3 --name ${target_share_name} \
--share-network ${share_network} \
--share-type ${share_type_name} \
--metadata source=snapshot \
--snapshot-id ${snapshot_id}
