Yes, but it's dangerous. By not partitioning a tebibyte hard disk we're 
exposing gratituously our beloved data.

The first thing a computer user has to learn (and I'm talking in general, 
not specifically to you) is "backup, backup and backup". Then you can 
start to play and enjoy your system. People tend to treat their computers 
like "washing machines" and heck, not, is not the same :-)

Yes, and that's why my primary backup is directly attached to one of the 
SATA ports of the motherboard: speed between SATA buses is good enough 
when using a powerful system. The average size of my /home backup is now 
at ~10 GiB and I always do full (not incremental nor differential) 
backups becasue 10 GiB is still a manageable size (although for servers 
and workstations I do differential backups).

Yes, but I'm very reluctant when it comes to optical media: it's painly 
slow, hard to deal with (requires from extra software) and data on them 
does not last "forever" despite what advertising says (moreover, 
rewritable media has a limited number of writes).
