I'm very interesting in having an incremental backup tool for Ceph, so 
if it is possible for me to do, I would like to take a shot at 
implementing it. It will be a spare time project, so I cannot say how 
fast it will progress though.

If you have any details on how you would like to see the implementation 
work, please let me know!


Thanks in advance,
