----
a 'backup' of an ext3 filesystem to a vfat filesystem can't really be
considered a backup but rather a copy since there really isn't much hope
for 'restore'
I have never seen the practicality of hard drive backups with removable
drives. It's always the human element because given any other options,
humans will fail. It's entirely predictable. Sure they will commit to
getting it done and perhaps succeed every day for the first year or so,
but...
