Ceph - Clones of RBD Snapshots are showing updates that were done to parent image after the snapshot was taken

Solution Verified - Updated -


  • RBD snapshot of an image that resides on a VM is taken and then later the RBD snapshot is cloned, changes made to the parent image after the RBD snapshot was taken will show up on the cloned image. The RBD snapshot should be a point in time copy of the image at the time of when the snapshot was taken, since the image is continually being update after the snapshot this effectively nullifies this backup for that point in time.
