Provided you have Lion, and icloud set up on your computer, and an external hd connected to your router you can use "back to my mac" and be able to access the files from any where you have an internet connection. DropBox is very good also (like Csound1 suggested.)
SuzieStitcher, maybe you can help me. When I try to Back Up Quicken Essentials (on my 2102 iMac, Mountain Lion) to Dropbox, the file saves fine in the Dropbox folder on my computer, but when I access Dropbox.com, there is a useless Packages folder there instead of a file. Any ideas?
I dragged a screen shot in here and also copied and pasted but I guess I don't really know how to do that. Anyway, the folder contains what the file consists of, the bits and pieces, but not the file itself.
