True - which is kind of weird, because as far as I understand their respective "databases", borg would be more suited for arbitrary remote storage because it should only need a "upload file" command basically without any interactivity, except for its robustness checks and some additional flexibility (having multiple backup sources, deleting data that is no longer needed).
Restic seems more made from the ground up to utilize the existing power of a filesystem as a database, so it needs remote storage that offers quick interactivity (esp. checking existing files), i.e. it's impossible to use something like Glacier as a backend.
It's not a problem for me since I just backup to a local drive and (am planning to setup) synchronization to a remote dumb storage.
