I am not a programmer, just a dumb user that thinks the whole thing is
kinda magic.  So perhaps this is a stupid question.  But since
BackupPc somehow knows where all the files are and what is linked to
what etc. why can't there be a button in the CGI interface that
instead of "restore", says something like, "as of the last inc or
whatever, make a perfect copy of what i want over here" and just let
that replicate the pc directories and pool and everything over to the
backup, offsite, or external drive?

P.S. I have been using this software for about 6 months, love it.  But
still have not succeeded in backing IT up without a crash.  Have tried
cp -dpr and also rsync with -H but both bombed out with "too many hard
links" errors.  If I could get this backed up i'd say it was the
perfect backup solution.
