Ich möchte Borg Backup als Backup-Lösung verwenden (Backup auf Remote-Server). Borg bietet ein sehr praktisches sh-Skript an, das man angeblich einfach als Cron-Job ausführen kann. WährendDas Skriptfunktioniert einwandfrei in der Befehlszeile, aber nicht in Cron.

Ich verwende Debian Bullseye.

Wie kann ich es auf Cron ausführen?

Hiereine ähnliche Problembeschreibung, allerdings ist mein Repository verschlüsselt.

Anmerkungen

  • Ich habe Borg Compact aus dem Skript ausgeschlossen, da dieser Befehl unter Debian Bullseye nicht funktioniert.

Ich bin sehr froh, Hilfe bei der Lösung dieses Problems zu bekommen!
