Great!
My preference for backing up the configuration is to export the jobs as json files. From the main menu, click on a job and then click Export. The default is to export to file (json) and include passwords. Adjust to your liking. Store this file in a safe place!
I also save all the global/default settings. From the main menu, click Settings, scroll down to the Default options area, and click the blue “Edit as text” link on the right. Copy the entire contents of this box and paste it into an empty text file. Store in a safe place.
