.. -*- rst -*- Volume snapshots (snapshots) ============================ A snapshot is a point-in-time copy of the data that a volume contains. When you create, list, or delete snapshots, these status values are possible: **Snapshot statuses** +----------------+---------------------------------------------+ | Status | Description | +----------------+---------------------------------------------+ | creating | The snapshot is being created. | +----------------+---------------------------------------------+ | available | The snapshot is ready to use. | +----------------+---------------------------------------------+ | backing-up | The snapshot is being backed up. | +----------------+---------------------------------------------+ | deleting | The snapshot is being deleted. | +----------------+---------------------------------------------+ | error | A snapshot creation error occurred. | +----------------+---------------------------------------------+ | deleted | The snapshot has been deleted. | +----------------+---------------------------------------------+ | unmanaging | The snapshot is being unmanaged. | +----------------+---------------------------------------------+ | restoring | The snapshot is being restored to a volume. | +----------------+---------------------------------------------+ | error_deleting | A snapshot deletion error occurred. | +----------------+---------------------------------------------+ List snapshots and details ~~~~~~~~~~~~~~~~~~~~~~~~~~ .. rest_method:: GET /v3/{project_id}/snapshots/detail Lists all Block Storage snapshots, with details, that the project can access, since v3.31 if non-admin users specify invalid filters in the url, API will return bad request.
