How can I backup my files?

Problem: It's not really obvious to me where TrailRunner mini stores the main document containing routes. How can I backup these files?
Solution: TrailRunner mini stores files in the following locations:

The main container is in either of these locations
__yourhome__ > Library > Containers > TrailRunner mini > Data > Library

within that container, the following files are being stored:
Application Support/com.berbie.trailrunnermini/TrailNetworkStore.sqlite
Application Support/com.berbie.trailrunnermini/com.berbie.trailrunnermini.log
Application Support/com.berbie.trailrunnermini/TNRoute-Attachments

Hint: The __yourhome__/Library folder is invisible by default. But just hold down the option key while pulling down the Finder's "Go" menu to get there. Or you can make it permanently visible using the following terminal command:
chflags nohidden ~/Library/
or you can open it by typing the following into the Finder menu item Go > Go to Folder box:
