I made reference to this program in the BF 3 forum, but it may be of interest to others that don't play and/or read the BF 3 forum. Game Save Manager is a great free little utility for backing up your game saves, and has some useful features like Steam Spreader, Dropbox/FTP support, archive verification, frequent database updates, custom entries, etc..

I recommend using the Seperate Archives settings. ;)
