[linux-lvm] Block Diff Utility

[Ritesh Raj Sarraf <rrs researchut com>]

Hi,

LVM Snapshots stands as a very good tool for backup and recovery.
I have my root on an LV. To have a backup, I just need to create a snapshot 
of my root LV and then dd the snapshot image.

Works perfect. Infact I have been able to restore the root LV to a different 
machine without any issues.

I was just wondering if there are block diff utilities. Because currently, I 
can't see a way to take incremental snapshots.
