Backblaze charges $5 per month for unlimited backup (down to $4 with a 2-years subscription), which was a very good deal back then.

(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. I had been using Backblaze backup for about four years and while the service and the client is excellent, allowing anyone to easily setup backups, I think it’s time to move to a solution I own more control of for the following reasons:

Recently, I’ve migrated my personal backup from Backblaze Backup to B2 (an online S3-style file storage, also by Backblaze).
