In this Chapter we will Backup the Docker- Volumes and the Data of the home- Directory of Docker, that is important. We will NOT do a full Backup of the Server, while Docker can only archive what is accessable by the user of docker (rootless!).

Further we will need a working Nextcloud- AIO with working Nextcloud- Backup preconfigured

The benefit of this is, that all the contents of docker will be backed up with the right acces-rights and configurations an we can rely on the functionality of NC-AIO here.
