For very plain excel and other docs you are ok with google docs. As soon as it gets a little more complicated then that, it will lose its functionality, as I experienced first hand...
I had an excel that I configured to calculate by inputting bookmakers odds, how to always make a profit.
It was a beautiful piece of work, and now its worthless, both the calculations as well as layout are gone...
are u saying you have a formula that i could make money in a foolproof way?
by the way, it doesnt stop at backing up your computer. what about your online storage? have u seen the horror stories online about people who've lost stuff. i've been trying to figure out the best way to backup my entire google account, i have pretty much gotten enough down:
1.
http://www.dataliberation.org/i believe its a google created site, it will guide u through a lot of stuff
2. have all your email forwarded to a google apps account.
that way u have a backup already, plus google has a little program to export and import mail between google apps accounts. its called google email uploader, you should be able to find it
3. i know gladinet has an option to transfer from cloud to cloud, never used it yet
4. share all your docs with another account and make a copy (with one click)
5. can this be done nicely for gmail through outlook?
