I've had to recover my database, thumbnails, and source configuration enough times that I just wanted a quick easy way to back them up. That is what this addon is meant to do.
Running the program will allow you to select Backup or Restore as a running mode. Selecting Backup will push files to your remote store using the addon settings you defined. Selecting Restore will give you a list of restore points currently in your remote destination. Selecting one will pull the files matching your selection criteria from the restore point to your local Kodi folders.
For more specific information please check out the wiki on Github for this project. Advanced descriptions for the following are all there:
