Folder Sync
Folder sync allows you to copy content to folders and external hard drives, for backup as well as archiving in multiple resolutions.
When content is archived in multiple resolutions, Emby apps will automatically choose the version that is most efficient for them. This will help relieve stress on your server's CPU.
To install folder sync, open the Emby Server Dashboard and navigate to Sync -> Services.
Click on Folder Sync underneath Available Services.
Then proceed to install it on the installation page.
Once installed, it's time to start adding Folders.
