Would recommend the above as I have just managed to store all my data and back ups (sage) on to here, and it dates back to dec 2008 so there is quite alot of data, and it's foc and easy to use!.
Thought I would share with you as you may fine this useful and not have to worry about data loss etc. I am going to back up on at least a weekly basis, or when I next do some work. It's still part-time, so every time I do a few hours work I will back up.
Took a while but then look at how much data I was backing up and shouldn't take so long next time!. yippe, love it especially as it's free.
