Hallo zusammen,
nachdem ich am Wochenende meine native Nexcloud-Instanz erfolgreich in das Betriebsmodell docker umgezogen habe, möchte ich dem Forum gerne mein angepasstest Backup-Script zur Verfügung stellen. Ich verwende ein Nextcloud-Image von Linuxserver inkl. mariadb und redis. Hintergrund dafür ist ein docker-Problem "random-number-generator".
Da ich sowas hier noch nicht gemacht habe, hoffe ich, dass ich diese </> Funktion des Forums richtig verwende.
Bei Interesse kann ich gerne auch eine rudimentäre Anleitung des Umzugs bereitstellen.
cheers,
