I would observe that with DVCS, if your hard drive crashes you can still lose several days of unpushed code, too. I recommend and use cron jobs to push and/or rysnc things around on a more frequent basis for my really important stuff.
One of the first thing I did when I got the new computer was to put a symlink to my projects directory in my Dropbox folder, so that all of my projects now get backed up to Dropbox automatically.
git push origin develop
Personally I have a mirrored drive set that I use as my primary storage, and a third disk that I rsync to nightly and use for backups of other stuff, because I don't trust that I won't have filesystem errors or controller problems that might render both disks in the mirror unusable. Then on top of that I use Crashplan to ensure I have an offsite copy.
For most of my code I also push to github or private external repositories regularly and/or pull to my laptop.
Maybe a bit paranoid, but I've had to recover from enough scary hardware and software failures over the years to not want to take risks.
