@BrutalBirdie said in Backup uploading stalls:
I have the same problem very often with Hetzner Storage boxes. No matter if CIFS or SSHFS.
I'm another Hetzner Storage Box user. I very occasionally have this problem too. I use CIFS. Anecdotally in most case it has been instances of PeerTube that it seems to get stuck on. I've no idea why. But running a backup of the app by itself has, I think, sometimes made the next backup work again.
Have you got PeerTube installed @nichu42? If so, perhaps try that? (or if not, try running a singular app backup on whatever app it is stalling on)
