I don't think anyone said anything against Jungle Disk. I usually speak out against Carbonite. Their restores are slow and the limit your bandwith once you reach a certain amount. The application has been iffy for me as well. I actually moved to iBackup. Man, their restore speeds max out my connection here at UCLA. I was downloading at 12 Megabytes a second (~100 Megabits/second). I downloaded my AC database in under 20 seconds. They also have a mail-in service for large backups/restores. (I believe it's free if you sign up for their 500GB plan). A lot pricier than other backup services out there, but it backsup SQL, SharePoint, Exchange, System State, and good ol' files.
