Hello Everyone,
since all topics around having a mirror server for Nextcloud are old and without any comprehensive solution, I want to ask it again to sum up all available solutions.
can anybody describe the best solution for having 2 running instances of Nextcloud at the same time, and their data would sync together automatically?
in short
You would setup 2 instances that share the same sql database and use the same redis server and both have the same nextcloud/data location and correct permissions.
