Haven't done pst files but since other databases do well with dedupe
there is no reason to suppose they wouldn't.   Dedupe is typically done
at block level rather than file level so the fact the pst changed in and
of itself shouldn't be a concern.  If however the pst somehow got
reorged everynight it might be a concern.   (That is to say adding info
to a file and changing its time stamp and size doesn't negatively affect
a dedupe but a compact/defrag of a file might as the data isn't really
the same after that.)

What are your experiences backing up Outlook .pst files?  Do they
de-dupe well?  

I know that each night we do a full backup of each file.  This is just a
characteristic of the file.  Outlook connects to it for read/write
access so just openning it causes a full backup of the file to be done
each night.

Please don't go on about not using .pst files.  If it were up to me I
wouldn't be backing up all of the .pst/.mp3/.avi./jpg etc. files not
save in certain locations (Well maybe the mp3 files until I have a copy
elswhere :))
