Hi,

for a backup program I have to find all differing files
(including metadata) in two snapshots taken from the same
subvolume.

Having looked at the find-new command I thought about this
process:

1. Get the two transids when the two snapshots were created.

2. Query modifications to the original subvolume between the two
   transids.

Is the general process corrent or have I overseen something?

AFAIS the btrfs tool does not provide the required
information/commands. Would it be possible to add those?

Thanks in advance,
  Arvin
