I found that rclone is enough for me. One backup to locally attached external drive with rclone sync. I add --backup-dir to keep older file versions separate, which I clean up with rclone delete based on their age. I also setup remote backup to OneDrive. rclone also takes care of the encryption for this one to protect from any snooping.

holy crap, i forgot i had heard about this 5 or so years ago.

I wish mojang would have left this in the game

A PSA for you is that the original setup for local invidious is not really worth it at this time. You gotta rotate IP to avoid youtube blocking it, you need to use IPv6, and you have to constantly refresh PO tokens. All of this happens with separate programs so it’s clunky and can’t keep up with youtube’s rate of blocking things, unless you setup some kind of frequent cron jobs, but at the cost of bringing the service down frequently which is not worth it.

For my instance I use the companion setup. It takes care of rotating PO token by detecting when it needs to. It’s also way more robust, based on very well maintained youtube.js project.

Another change I made is routing the invidious connections through VPN. That keeps my real IP safe from getting blocked, and I do remember this setup rotates the VPN server when blocked. I’ll share my compose file in a bit, been using it with almost no issue for almost a year.
