I use Mozy, which is IMHO a better solution.
there are some compassions between them on the web. Mozy
is always the best options.
(I started using Mozy following Scott Hansleman
recommendation)
I use also Carbonite for more then a year now. It's
really great. Last week I visited TechEd Barcelona and
my data folder was not updated for a week. The next
Monday I've got a message of Carbonite that my backup
has not run for a week... Little things what makes this
product really great.
And... Unfortunately I needed to test the restore
function a couple of times ...and it worked :-)
Carbonite is my lifesaver!
I liked MyOtherDrive's interface much better than
Carbonite's, and at free I love the price, but
MyOtherDrive doesn't have the Explorer menu that lets me
backup automatically.
