So just remove the cron job from /etc/cron.daily and run it manually
as and when you like, and let it do a full backup each time?

Alternatively you could add a line to /etc/cron.daily/backup-manager

test -f /media/disk/some_file_only_on_usb_disk || exit 0

So it only backs up if the usb disk is attached (and that file exists on it).

It's very flexible. Take a look at the conf file which contains lots
of comments about what the options do. Worth a look.
