For me, i use Dropbox for small backups from my phone, and every so often I backup my phone onto my desktop. I have each of my phone backups in a folder. This folder is then copied onto two other drives for safe keeping. For other pictures and such I just have them broken down of where they originated ie: skype, facebook,downloads from specific websites, etc. Then I follow the same process as above.
