I’m not sure, but I think you’d just need to create a script which stops them, runs the backup, and then restarts them.

Some people would say that you’re doing something wrong by using Duplicati, because they’ve had problems restoring data and it’s very slow, so if you’ve never had to restore data before you should test that to check that it works, and maybe switch to something else like Borg to be safe.

Also, backing up the folder without stopping the containers first might result in any backed up databases being corrupt, so if you’re running anything that uses databases, you should stop those containers before backing up the folder.

I checked and his TV is a Samsung UE40ES5500 which he bought in 2013, so I’m pretty sure it doesn’t use Tizen unfortunately.

Yeah, I use one myself. He’s already using all the HDMI ports on his AV receiver though, so there’s no room for any extra devices.

I know modern TVs can send the audio from the TV to the receiver, so in theory he could plug the stick into the TV instead, but his one seems to only be able to send certain formats that way, and you can’t see the receiver’s overlay on the TV when using it that way, so it’s impossible to adjust anything.

Definitely no Play Store on his TV. I don’t think it has any Chromecast /Airplay apps either, but even if it does I don’t think they’re any substitute for Plex or Jellyfin.

His TV is a few years old, so I’m not sure if it uses Tizen but I’ll have a look, thanks.

They mean Smart TVs. My Dad’s Samsung TV has a Plex app, but no way to install anything like Kodi that would let him use Jellyfin instead of Plex to serve media.
