request for 'testing configurations'

[aliasname]

Mainly to Simon but perhaps someone else already knows about a possible workflow.

Simon trapped me with a problem where he directly guessed how I was albe to archive it. I did copy contents from a MininServer's .config file on my local (Windows) machine to a besides running MinimWatch Frontend dealing with the MinimServer on my Syno.

You might ask why?
Because I spent too much time in trying a new config which didn't work and then had to establish the old config followed by another 3-4 hrs library scan.

What I do miss is something in common called 'snapshot', which does safe all configs and allows for a rollback.

Any idea if that's possible already?
