Hi.


Regarding this attacks involving snapshots and the total amount of data
written to an encrypted volume.

Is there an easy way or perhaps even a working tool, which accounts the
total amount of bytes written to a given block device (either directly
or via something that is on top of that block device (filesystem or
other block device layers)?

Cheers,
Chris.
