Well, yes, but one of the reasons you make backups is to cover the case 
where you meant to type 'rm -rf something*' when you are in the root 
directory and accidentally type 'rm -rf something *' instead.  Or a 
software bug that does something like that.

Yes - but it would be even better if you rotated 2 such disks - or ran 
over the network to another box.

You can either do the obvious script that rsync's each partition and let 
cron run it, or look up one of the packages that keeps some history, 
like rdiff-backup.
