Other users will have personal experience, but here are the answers based on the PC Mag review:
Ruth asked:
1. I know the data is encrypted, but I worry about how safe and private it is. Theoretically could someone at Carbonite view my files?
**According to the PC Magazine review, you can assign your own encryption key to make it so that no one can access your files - Even Carbonite. However, if you do that, you need to keep it safe in a couple places that you could access regardless if there were a disaster at your home or office.
2. What happens if Carbonite goes out of business? Besides finding having to find another provider, does Carbonite somehow have part of all of my data and files? That makes me uncomfortable.
**Yes, they would have your files, but no way to read them, according to PC Magazine, if you used your own encription key.
3. For those who use Carbonite or a similar program, do you still use a manual back-up or do you rely completely on the program?
I'm planning to continue doing a nightly backup on my external drive.
