I use Backblaze B2, but stored in an encrypted Restic container, set up using this guide:
Restic has been great for automating backups, and even letting me mount the encrypted storage to grab individual files. I like doing it this way since I don’t have to trust Backblaze isn’t reading my data - I know for sure that they can’t.
Performance of storage that is both remote and encrypted is about what you would expect, but I don’t need access to the data unless something bad happens.
People need to understand what this will mean from a developer perspective before getting all up in arms. This initiative is more kneejerk emotional than it is realistic.
