Hey,

I have set up borgmatic according to the documentation. Folder /data/conf/borgmatic/ssh has the private, public keys files id_ed25519 and id_ed25519.pub with chmod 0600.

The folder /data/conf/borgmatic/etc has the files config.yaml and crontab.txt

If I run the manual archiving with docker compose exec borgmatic-mailcow borgmatic -v 2, everything is fine after asking the ssh password.

If the cronjob is running, than it will not do the job. I cant find out what the reason is. Would be happy if somebody can read out from the logs. I can see only the part with permission denied and guess the keys are the reason.

Crontab file exists, using it

I am using Hetzner to backup and Hetzner has documented to add the ssh keys to the enviroment with $ export BORG_RSH='ssh -i /home/userXY/.ssh/id_ed25519'.
Would it be correct to add it and if yes is that correct $ export BORG_RSH='ssh -i /home/userXY/.ssh/id_ed25519 ?
