Hey, I thought it’d be nice to let you know: I’ve just merged a PR which updates the library we’re using for accessing BackBlaze B2 (https://github.com/kurin/blazer) so that restic now supports “Application Keys”. Before, you could just have one set of credentials for accessing B2, which could not be restricted. With Application Keys, you can now create several credentials with different access privileges, e.g. you can restrict an application key to a specific bucket and/or path.
Let us know what you think!
