As you already know, my knowledge of syncope internals a limited to say
the least, hence might be wrong.
However... This works for me..
https://syncope.apache.org/docs/getting-started.html
Chapter 3.1.1. Components
States that in order to persist data for the embedded database one
should modify the file -->
|webapps/syncope/WEB-INF/classes/persistence.properties|
The line mentioned in the document does not exist nor does anything
happen if adding it.
Instead I had to change the Master.url in the file -->
webapps/syncope/WEB-INF/classes/domains/Master.properties
