True.  I had not thought of it as a daily backup.  We don't know if
that's what the OP wants to do, or a backup once per month in which
case it would not work.  I was left with the impression that this
would be a monthly backup of 1TB, later dropped to 50GB, and
ultimately dropped to 20-50GB.  Because his very first posting had "to
a set of DVDs", it lead me to believe that this would be a single
monthly backup of that quantity of data.  Not that amount of data
spread out daily throughout a month.
