etag property
etag
is used for optimistic concurrency control as a way to help prevent
simultaneous updates of a restore from overwriting each other.
It is strongly suggested that systems make use of the etag
in the
read-modify-write cycle to perform restore updates in order to avoid race
conditions: An etag
is returned in the response to GetRestorePlan
, and
systems are expected to put that etag in the request to
UpdateRestorePlan
or DeleteRestorePlan
to ensure that their change
will be applied to the same version of the resource.
Output only.
