(When I do a restore, the encrypted data should be downloaded on my computer and decrypted locally, not decrypted on their system.) They also provide an alternative option where I can specify my own key, but last I’ve checked, I will need to provide them the key when I attempt a restore, which is a no-no.

By default, Backblaze uses an encryption key provided by them which means that they can decrypt all data. I want a backup system where, by cryptographic design, the backup provider cannot access and decrypt my data. Fallen in the wrong hand, it could be used to impersonate my account in many websites. By default, Backblaze uploads nearly all files in my user folder, which includes my browser cookies. Security is a very hot topic nowadays and you really need to trust your backup software.
