etag property

String? etag
getter/setter pair

etag is used for optimistic concurrency control as a way to help prevent simultaneous updates of a BackupPlanBinding from overwriting each other.

It is strongly suggested that systems make use of the 'etag' in the read-modify-write cycle to perform BackupPlanBinding updates in order to avoid race conditions: An etag is returned in the response to GetBackupPlanBinding, and systems are expected to put that etag in the request to UpdateBackupPlanBinding or DeleteBackupPlanBinding to ensure that their change will be applied to the same version of the resource.

Output only.

Implementation

core.String? etag;
