Fortunately, I've never had to use it. $59 a year for my business, one computer only. Auto-pay from a credit card. There was an incident where I had to get a new credit card because the account was compromised. I updated the info on Carbonite but the auto pay didn't work and they cancelled the coverage. I was able to straighten it out easily by calling customer service. Only took 5 minutes.

Neither of us have had any problems with them. I forget they are even on my computer until it is time to renew.

Been using it for years, and after two hard drive crashes several years apart, Carbonite restored most everything.
Our most important files are specific to the CAD software we use, and file types not commonly used must be flagged so Carbonite knows to automatically back those up.
Very easy to use, invaluable when you need it.

like the way it does backups and restores. One of the best things about it is that they a history of backups so that if you accidentally erase a file and don't notice before the system backs up again, you find the file in an older version. One hint: if you erase a file by accident, immediately "freeze" the Carbonite backup process so that you can restore it before it gets lost. It's in the cloud, so you can access all your files anyplace you happen to be, on any computer or mobile device.

screwed up my computer and caused me to lose many of my older Word files I went to Carbonite and was able to recover all the files I needed. I think it's great.
