I have 3 VPSs (little servers). Two in different US data-centres, and one in Australia (where I live). Total cost ~$50 / month. (I use prgmr.com and crucial paradigm.)
I replicate everything that I care about (e.g. code, web-sites, mail) across my home computers, my work computers and these VPSs, using git.
As a bonus, it keeps a complete history of my work, and compresses it; and it’s lightning fast. I use it for mail, because it’s faster and better than IMAP.
No need to back up movies that you downloaded off bittorrent, you can download them again. Just back up your code and data. Go, make yourself some off-site backups scattered around the world, and do it now!
I also publish nearly all of this data (my code) on the web as a side-effect of committing it to my servers whenever I make any changes.
