I have so much content (+/-30 tb) I have to just copy content between two servers as I have not found a backup solution viable. I do all the metadata editing, playlists, art corrections on Server 1 (S1), and just let Plex handle all but the worst errors on Server 2 (S2). It would be great to occasionally copy over the Plex database and images so they match completely and all my changes don’t risk loss.
mirrored plex servers is not something that is supported.
it is possible to clone or use a backup database, copy it to a different server, but that would be a one time deal, plex does not support any type of sync between servers.
