for all objects referenced in the snap.
Perhaps if you wanted to script this, then parsing the above output for time
stamps that are after the previous snapshot.
Deleted files (and of course new files) can be diffed against the list for the
snapshot you want to compare with, but I assume you also want files that have
been modified, hence the requirement to parse the above outputs.
Unfortunately time does not permit me to come up with a working solution until
(really snowed under until mid next week - did someone say there is meant to be
a weekend in their too?). But I am sure there is enough info here for someone
to hack together a script.
Cheers,
Darren Mackay
