One day I was scrolling through my Youtube Favorites playlist, and was devastated to discover 10-20% of the videos were deleted or unavailable. The worst part is it's nearly impossible to get any information about which videos were deleted, so I can't look for re-uploads or even know if they are worth looking for in the first place. Ever since then, I run a script to periodically backup my Favorites playlist with youtube-dl. More generally, I've learned the hard way to never trust that any content on the internet will stay up forever. If something is important to you, back it up, sooner rather than later. The Internet Archive Wayback Machine is great but it does not backup everything!
