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. |
