Nextcloud version (eg, 12.0.2): 12.0.0
Operating system and version (eg, Ubuntu 17.04): Asustor NAS
Apache or nginx version (eg, Apache 2.4.25): no idea
PHP version (eg, 7.1): no idea

The issue you are facing:
Installed and configured nextcloud on my Asustor NAS
All works fine, but I would like to upgrade to newer version and do a backup before that
On my Asustor NAS MariaDB is running and I can connect to it via PhpMyAdmin, but there is no nextcloud database. Is it possible that my nextcloud installation runs without a database? Is there a way to find out which is the name of the database used by my nextcloud installation?

Is this the first time you’ve seen this error? (Y/N): Yes

Steps to replicate it: not applicable

Looks like you use sqlite3 as DB.
I searched for a the command to perform an sqlite3 backup real quick:

Looking at the suggested solution, you can search for *.sq3 files on your system, to find the database.
I hope it helps.

Yes, yours is using sqlight3.
