Plex currently has an option in its settings to allow a scheduled task to run every 3 days to do database backups. Personally, I wouldn’t mind those backups happening more frequently. Maybe every day.
My main reason is wanting this is when I’m messing with metadata, specifically music metadata and its ratings and whether or not its on a given playlist. It can be very easy to mess up metadata while letting plex scan for content after I’ve messed with the files.
Oh. I absolutely agree that this would be really easy to setup myself. That’s just the thing, though. This would also be really easy for Plex to implement (I think).
