How private and secure is Backblaze B2? (lemmy.dbzer0.com)

I'm looking into getting an extra backup solution for my laptop, and a backup solution for my NAS/media server. Currently, my laptop backs up to my local NAS, and Proton Drive, while my server has no additional backup.

Is using something like Backblaze B2 actually private and secure, especially if I use the personal encryption key I can set? Or is there another online service that may be better and more private?

Some options:

encrypted file stored on a free tier data storage (many are free for the first year)
Tarsnap - dedups so storage is cheap; for keys, this would be pennies per month

I am confused, aren't you just pushing the problem further up the chain? Now you need to worry about storing the key that decrypts the file storing the key you wanted to protect in the first place.

Same goes with tarsnap, now you need to worry about where to store the tarsnap keys.

You'd use a password to encrypt the keys and/or store that key in your password manager.
