nextcloud is setup using the well known tutorial by @macom.
problems and additional thinks are fixed with the support topic.
now, all is running well and configured (moved from google to my nextcloud inkl. contacts, calender and thinks like this) i come to the ask "what will happen if my system crash some time, or i have to resetup - maybe for omv6 oder 7 or what ever ...
backing up the data part of nextcloud is not the problem, i just let it resync to another location.
also found a little script to backup my calenders and contacts - but - what is to do to backup the database - and how to restore in the case of need.
what are your solutions?
i have no experiance with db - most cases i have to use db in the past was just "click next in setup, say yes to all and just run your program" never need to work with the db - in most cases a reinstall on other system works like "copy the file xyz.db to the folder "bla\" and start the program, it will find the db and work with this db" ... xD
best (for me) would be a script for given setup (nextcloud in docker etc.pp) with the opinion to backup and restore - to just let it run with a cronjob.
