The short answer ( :-) ) is, use a journaled file system on your back up drive, or RAID or something with some sort of redundancy checks. Individual bit errors can always occur, although when a drive goes, usually a whole portion will go and you will notice pretty soon, e.g. your backup of backup may start to fail. If you are paranoid, do an equivalent of disk check every week or month or whatever.
