The route I personally take is to dump the list of files using list-current-files
, as you suggested, but then use grep
instead of diff
to see the differences. An example of such is below:-
duplicity list-current-files --time now "$" > /tmp/today
duplicity list-current-files --time 1D "$" > /tmp/yesterday
grep -Fxvf /tmp/
This would check the differences between the latest backup and yesterdays backup, but if you need to check two different dates you can replace now
with any other accepted time.
