Hi,
i had setup borgmatic according to following documentation:
https://docs.mailcow.email/de/third_party/borgmatic/third_party-borgmatic/#erstellen-sie-dataconfborgmaticetcconfigyaml

I am using as targe hetzner storage box. By executing the backup manual its works, when it is executed by crontab its failed. Do someone know what could be the issue ?

When i am executing following command, i get a sucess backup into the logfiles:

root@mail:/opt/mailcow-dockerized: docker compose exec borgmatic-mailcow /usr/local/bin/borgmatic –log-file /etc/borgmatic.d/borgmatic.log –stats -v 0 2>&1
