It didn't backup my data, then wouldn't refund half of a 2-year renewal when the data was lost. I had it for many years and didn't need it, but when I suddenly lost 200 MB of data I immediately stopped using that computer, copied the remaining documents on it to a hard drive, and ordered a full backup on a hard drive from Carbonite. After the Carbonite data was installed on the new computer, it was shocking to find that the folders didn't have all of the data that should have been backed up. One folder had one document when 23 documents should have been there and still existed on the hard drive copy of the documents on the old computer after the crash. That means they either never backed up or Carbonite lost them. I was half way through the 2-way renewal, but Carbonite will only issue a refund within 30 days of the INITIAL purchase even though I must cancel because of their BAD service.
