+================================
+Taking Backups for your Workload
+================================
+
+The MicroCeph deployed Ceph cluster supports snapshot based backups
+for Block and File based workloads.
+
+This document is an index of upstream documentation available for snapshots
+along with some bridging commentary to help understand it better.
+
+RBD Snapshots:
+--------------
+
+Ceph supports creating point in time read-only logical copies. This allows
+an operator to create a checkpoint for their workload backup. The snapshots
+can be exported for external backup or kept in Ceph for rollback to older version.
+
+Pre-requisites
+++++++++++++++
+
+Refer to :doc:`How to mount MicroCeph Block Devices <../tutorial/mount-block-device.rst>`
+for getting started with RBD.
+
+Once you have a the block device mounted and in use, you can jump to
+`Ceph RBD Snapshots`_
+
+CephFs Snapshots:
+-----------------
+
+Similar to RBD snapshots, CephFs snapshots are read-only logical copies of **any chosen subdirectory**
+of the corresponding filesystem.
+
+Pre-requisites
+++++++++++++++
+
+Refer to :doc:`How to mount MicroCeph CephFs shares <../tutorial/mount-cephfs-share.rst>`
+for getting started with CephFs.
+
+Once you have a the filesystem mounted and in use, you can jump to
+`CephFs Snapshots`_

 Mount MicroCeph backed Block Devices
 ====================================
 
-This tutorial will guide you with mounting Block devices backed by a
-MicroCeph cluster.
+Ceph RBD (RADOS Block Device) are virtual block devices backed by the Ceph storage cluster. 
+This tutorial will guide you with mounting Block devices using MicroCeph.
 
 The above will be achieved by creating an rbd image on the MicroCeph deployed
 Ceph cluster, mapping it on the client machine, and then mounting it.
