Never tried carbonite but did use EVault for our servers back when I was in IT. Their Endpoint Protection is pretty good too. http://www.evault.com/
Mike, I'm a Carbonite user and here's an earlier thread I started when I was looking for backup options and feedback: http://www.ferrarichat.com/forum/showthread.php?t=315887 As luck would have it rolleyes my hard drive or motherboard (which is still TBD) recently died () on our primary household computer and Carbonite saved the day. All files appear to be backed up and no issues accessing them online. I also had an external hard drive running backup but it missed the last day or so of activity so Carbonite proved better in that instance for me. Best, Steve
