Looks like neither Backblaze nor Carbonite support E2E encrypted backups where I do not have to send the password to the cloud, or the private key is in fact generated inside the cloud.

Which means I have to really scramble to find something else that is compatible with computer-illiterate family. Geez, not what I needed.

Backblaze supports a user-provided passphrase, which is used to encrypt your private key. That provides E2E security. It isn't used by default, though.

Arq encrypts the backups before transmitting them, and the encryption key you choose never leaves your computer.

Is there a way to share the encryption key between computers (manually set the key)? See my aside @ https://news.ycombinator.com/item?id=15075063 for why
