Programmatic Extract all reports from a server

I have users on our PBI Server who have overwritten a PBIX and now need to recover the previous version. I Can't see anything obvious that supports this other than restoring the ReportServer DB and extracting the content from there.

So I am wondering if there's something I can rig up that would extract all the current reports every day and archive them. Enabling me to keep copies where the users haven't employed any version control.

I have Powershells that do this for RDL files, am just wondering if anyone has idea if these would work for the PBIX files? Or if anyone has alternative ideas/approaches.

many thanks

Steve
