The native Backblaze B2 API is somewhat unspecified in places, or even incorrect in their docs. If you encounter any errors make sure to report them and they will be fixed.

WARNING

Do not include Protected Health Information (PHI) or Personally Identifiable Information (PII) in bucket names; object, file, or folder names; or other metadata. This metadata is not encrypted in a way that meets Health Insurance Portability and Accountability Act (HIPAA) protection requirements for PHI/PII data, and it is not generally encrypted in client-side encryption architectures.
