They have an option in software to enable encryption. You provide a key and supposedly the encryption happens at the client in your end. Obviously you have to trust their software and terms like you mentioned. Though backblaze has a great track record and is very open. If you don't want to trust them there are other softwares you could use to encrypt your data before giving it to backblaze.

But one of the benefits of backblaze is the simplicity. Simplicity of setup, backups, and restores. If you muddle with that by encrypting before giving to backblaze you lose out on part of the value.

It also usually seems when people roll their own it opens up risk of forgetting something. BB is easy, set up their encryption and you should be fine.

Just some thoughts.

For restore, though, decryption happens at the server end. You have to supply your key to their server, which decrypts the data at their end, then sends you the subset you are interested in restoring.

Is here a reason they don't just supply you with 5he encrypted data and give access to a tool to decrypt it?

This is the only thing putting me off backblaze

That is strange. The encryption, in that case, only really offers protection against data breaches
