Thats a smaller backup partition that I'd expect. What are you backing
up: just /home, and how many backup copies?

You do realise, of course, that a permanently online backup scheme like
that is fairly unsafe because lots of scenarios can kill it along with
the rest of the system. A better plot would be to backup over an ethernet
connection to removable storage on a separate system, keeping the backup
offline when not actually being accessed, and preferably having at least
tow generations of backup devices.

I've just bought a pair of 1TB WD Essentials USB drives. Yes, I know, I
should have bought them separately so they come from separate production
batches. So far they're looking good - quite a bit faster than the 320GB
2.5" WD Blue drives they replace and that will be too small fairly soon.
I make offline weekly backups of four systems (3 x 64 bit Fedora, 1 x RPi
model B) using rsync to put all four backups on the same disk. Both
backup disks are in a fire safe when not being used, so there is always
one backup copy in the fire safe.

Paranoid? You bet, when backups are involved.
