Exactly why I was specifically including:

backup  /var/lib/apt    localhost/
backup  /var/lib/aptitude       localhost/


As well I should (but neglected to) have added:

backup  /var/lib/dpkg   localhost/
backup  /var/backups    localhost/

but none of the other /var/ subdirectories which are for other packages.

Of course if install scripts for other packages change these
subdirectories when they are updated (I don't think they are suppose
too) then this whole idea wont work.
