Hey,
The UCS Nextcloud app stores data in two places:
- The configuration and the files are stored in the directory
/var/lib/univention-appcenter/apps/nextcloud/data. - A PostgreSQL database is used, too, on the same host the app is installed on. It’s called
nextcloud.
Therefore… back up the whole directory mentioned above and create text dumps of the database with the pg_dump utility. Then back up those text dumps, too.
Kind regards,
mosu
