    Just a heads up, I have seen some bad behavior with cifs mount and hard-links on my personal Cloudron, which made some backups corrupt.

    So please everyone who is using this for now with relevant data, do not use hardlinks.

    I'm not sure if this applies to me or not. I backup to a Hetzner Cloud Volume (not storage box). Currently I have hardlinks enabled. Should I turn them off?

    What should I look for in the logs to see if this is effecting me?

    Thanks!

    I use Cloudron with Gandi & Hetzner

      It highly depends on how a "disk" is mounted onto the server. The hardlinks issue is only there for cifs mounts and since cifs/samba support hardlinks since a very long time, this seems to be related in particular to the hetzner storage boxes at the moment.

        @nebulon OK thanks, so I don't think this applies to me.

        This is how Hetzner Cloud Volumes are mounted:

          correct in your case this should not be any issue as this is mounted like a regular ext4 which supports hardlinks just fine.
