I currently use an Ubuntu distro (Mint) with Plex installed serving media to my local network. I installed docker last night so I can test out some photo hosting services.
Is there a benefit to running Plex through docker vs the traditional method?
Docker containers are easier to backup and restore since the config folder is easily accessible. Also if your plex server is accessible to the internet it will be harder for hackers to take it over if there's any possible exploits.
Just out of curiosity, do you backup all the generated metadata too? I backup my Plex folder from my SSD to my unraid array weekly, and it takes quite a long time to get through.
You might want to look at how you’re backing up. Something like BorgBackup or better RSync scripts would benefit this process by only taking differences instead of a full backup. Unless you’re constantly adding and deleting media daily, a weekly Plex backup shouldn’t really take a long time.
