Bei Variante 2 des mounten scheint es zu funktionieren.

Danke dafür

[iobroker/zigbee2mqtt] TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string ... Received undefined

Ich habe im Code von BackItUp nachgeschaut. Diese Meldung kommt genau dann, wenn der eingetragene Z2M-Pfad nicht existiert. Die Meldung ist leider nicht sehr aussagekräftig. Es ist also so, wie vermutet: /home/pi5/docker/zigbee2mqtt_data/data gibt es nur auf dem Host, im ioBroker-Container nicht.

Prüfen kannst du das so:

docker exec -it iobroker ls -la /home/pi5/docker/zigbee2mqtt_data/data

Das wird "No such file or directory" liefern.

Also eine der zwei Varianten von oben:

1. Den Ordner im Compose beim iobroker-Service mounten (- /home/pi5/docker/zigbee2mqtt_data/data:/opt/zigbee2mqtt/data), docker compose up -d ausführen und in BackItUp /opt/zigbee2mqtt/data eintragen.
2. Oder in BackItUp auf Remote umstellen und dort IP, Port 1883, Base Topic zigbee2mqtt und User/Passwort vom Mosquitto eintragen. Dann muss nichts gemountet werden.

Ich würde Variante 2 nehmen, wie auch Marc schon geschrieben hat.

@Mico sagte:

Das verstehe ich leider nicht

Einfach bei "Backup Quelle" Remote auswählen und dann die MQTT Broker Daten ergänzen. Fertig.

Hier die Einstellungen des Backup Instanz

"Entweder du mappst den zu sichernden Pfad in den iobroker Container oder (was ich empfehlen würde), aktiviere das Remote Backup und trage deinen MQTT Broker ein."

Das verstehe ich leider nicht oder ist das von Blufox damit gemeint?

Ich vermute aber Folgendes: BackItUp läuft im ioBroker-Container. Der Pfad /home/pi5/docker/zigbee2mqtt_data/data existiert nur auf dem Host, im ioBroker-Container gibt es ihn nicht. Deshalb findet BackItUp dort nichts und bricht ab.

Du hast zwei Möglichkeiten:

1. Den Z2M-Datenordner zusätzlich in den ioBroker-Container einbinden

Im Compose beim iobroker-Service unter volumes ergänzen:

    volumes:
      - /home/pi5/docker/zigbee2mqtt_data/data:/opt/zigbee2mqtt/data

Dann den Container neu erstellen (docker compose up -d) und in BackItUp wieder /opt/zigbee2mqtt/data eintragen, also den Pfad, wie ihn der Container sieht. Der Benutzer im ioBroker-Container muss die Dateien dort lesen dürfen.

2. Remote-Backup über MQTT

In BackItUp beim Zigbee2MQTT-Backup statt "Lokal" den Remote-Modus wählen und Folgendes eintragen: die IP deines Mosquitto (nicht die von Z2M), Port 1883, Base Topic zigbee2mqtt sowie User und Passwort vom Mosquitto. Dann muss nichts gemountet werden. Der Restore läuft in dem Fall aber über Z2M und nicht über BackItUp.

Wenn es danach immer noch abbricht, zeig bitte das Log:

docker logs iobroker --tail 100

@Mico sagte:

Was will mir nun diese Fehlermeldung sagen ?

Dass du vom Container aus nicht einfach auf die Pfade des Hosts zugreifen kannst.

Entweder du mappst den zu sichernden Pfad in den iobroker Container oder (was ich empfehlen würde), aktiviere das Remote Backup und trage deinen MQTT Broker ein.

Was haste denn da nun exakt wo eingetragen. Davon könntest du mal (im Gegensatz zum Log, da macht es nämlich keinen Sinn) einen Screenshot machen.
