Right now my current backup of my data is as follows.
My desktop computer and my laptop computer both have btsync (http://www.bittorrent.com/sync/downloads) my main document files, this also replicate to a in home server (I also btsync my music folder to the in home server too) I then have a Virtual computer that I get though Digital Ocean (https://www.digitalocean.com/) I use this also for my SVN server for my personal projects) that also gets the btsync of my main data directory.
The next step on my backup system is I use cron to do backing up of my main data directory, I have a script that is kicked off that will make a tgz of my main data directory and places it in ~/backups/backup.tgz then at 1am on Sunday I have crontab scp the Sunday backup (the one that would have been taken only an hour earlier) to my Digital Ocean server.
