Roon keeps all of the information it gathers on your tracks and all your settings in a database file. It's a good idea to back this up for safe keeping.
To do this go into Roon using the desktop control app and go to Settings -> Backups
Select backup then Select Location... on the top of the dialog select sonicorbiter / storage you can do this by clicking on the / (next to the small drive icon) and selecting storage.
Then click on Select This Folder then Start
You can setup scheduled backups to the same location.
If you want to copy this backup off your sonicTransporter for safe keeping go to the sonicTransporter fileshare and copy the backup folder to your computer.
