Nextcloud Backup without Data

[msbt]

I've been using hardlinks for a few days now and encountered no problems so far. Would the backup job notify me if some links couldn't be generated? Not sure what happened the last time I tried that.

Yes you would receive a notification and email if a backup job failed

Seems to be working for me now too!

jdaviescoates - Do you mean the borgbackup to Hetzner storagebox - or the Synology pull?

Both! Thanks

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.

We have now setup a separate hetzner box to sync large amount of data to debug this issue.

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!

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:

[nebulon]

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