Well, I can tell you that I’ve used Carbonite for about 2 years now
on 3 computers. It has saved my butt more than once, is easy to use
(incredibly) and affordable. The only caveat is that if you do find
yourself having to do a major restore (a complete computer with a lot
of data) it will take a long time (multiple days for a really large
set of files) because it does the restore via download and tries not
to clog up the entire pipe. You can also do “file at a time” or
"folder at a time" restores.
The one thing that it cannot do, however, is restore something that
you deleted if you don’t realize it within a certain period of time
(I think it’s a month, but would need to double-check). So it’s not a
replacement for a periodical full-file backup to DVD or tape, but you
can just plan to do that once a month, rather than needing to do it
much more frequently.
Hope this helps!
