I use Carbonite both at home and at the office. It works great. I've had to restore files...yes of course it takes a while to download, but I love the that the backups happen automatically and effortlessly. Great of those of us who are not that techy in these sorts of issues. That said...also do onsite backups...ya just never know! Can't have too many back ups. (Take it from someone who has had more than one system failure)
Just keep in mind that Carbonite (even Business Premiere) does not back up SQL Server programs. You can only back up a backup of SQL. If you are running a server OS that uses VSS, you will be fine. Or, a 3rd party program such as Backup Assist that uses Open Files.
