How to save/backup Web Edition configuration?

I’m trying out this QNAP x86 qpkg: QNAP packages for testing.

How can I save/backup the configuration? Backup doesn’t show the directories below

/share/CACHEDEV1_DATA/.qpkg/Duplicacy

where the configuration is stored, so I can’t use Duplicacy.

Update: Found the answer here: Backup of Duplicacy config files
