Backups (backups)
=================
A backup is a full copy of a volume stored in an external service.
The service can be configured. The only supported service is Object
Storage. A backup can subsequently be restored from the external
service to either the same volume that the backup was originally
taken from or to a new volume. Backup and restore operations can
only be carried out on volumes that are in an unattached and
available state.
When you create, list, or delete backups, these status values are
possible:
**Backup statuses**
+-----------------+---------------------------------------------+
| Status | Description |
+-----------------+---------------------------------------------+
| creating | The backup is being created. |
+-----------------+---------------------------------------------+
| available | The backup is ready to restore to a volume. |
+-----------------+---------------------------------------------+
| deleting | The backup is being deleted. |
+-----------------+---------------------------------------------+
| error | A backup error occurred. |
+-----------------+---------------------------------------------+
| restoring | The backup is being restored to a volume. |
+-----------------+---------------------------------------------+
| error_restoring | A backup restoration error occurred. |
+-----------------+---------------------------------------------+
If an error occurs, you can find more information about the error
in the ``fail_reason`` field for the backup.
List backups with detail
~~~~~~~~~~~~~~~~~~~~~~~~
.. rest_method:: GET /v3/{project_id}/backups/detail
Lists Block Storage backups, with details, to which the project has access,
since v3.31 if non-admin users specify invalid filters in the url,
API will return bad request.

Restore a backup
~~~~~~~~~~~~~~~~
.. rest_method:: POST /v3/{project_id}/backups/{backup_id}/restore
Restores a Block Storage backup to an existing or new Block Storage volume.
The name parameter will work only if a new volume is created.
If UUID is specified, the backup will be restored to the specified volume.
The specified volume has the following requirements:
* the specified volume status is ``available``.
* the size of specified volume must be equal to or greater than the size of backup.
If no existing volume UUID is provided, the backup will be restored to a
new volume matching the size and name of the originally backed up volume.
In this case, if the name parameter is provided, it will be used as the
name of the new volume.
