+==================
+ RBD Snapshotting
+==================
+One of the advanced features of RADOS block devices is that you can create 
+snapshots of the images to retain a history of an image's state. Ceph supports
+RBD snapshots from the ``rbd`` command, from a kernel object, from a 
+KVM, and from cloud solutions. Once you create snapshots of an image, you 
+can rollback to a snapshot, list snapshots, remove snapshots and purge 
+the snapshots.
+
+.. important:: To use use RBD snapshots, you must have a running Ceph cluster.
+
+.. important:: Generally, you should stop i/o before snapshotting an image.
+   If the image contains a filesystem, the filesystem should be in a
+   consistent state before snapshotting too.
