In this brief guide, I will share what I've learned about archiving live webpages and recovering deleted webpages using various archive services.

Before you start

I highly recommend installing the Web Archives extension in your web browser (Chrome, Firefox). It provides quick access to archive services and search engine caches.

Overview of archive services & caches

Wayback Machine: Best and largest webpage archive. You probably already use it. Wayback Machine is the only archival service that also performs automated crawling, so its coverage is much better than other archives. See usage tips on Wikipedia.
Archive.today (also known as Archive.is): A mid-sized service that takes

200GB total boot volume space across all intances (minimum of 50G per instance)

Edit 🎉

All packages, except for Tini have been added to termux-root. To install them, simply pkg install root-repo && pkg install docker. This will install the whole docker suite, left only Tini to be compiled manually.

	Each YouTube video has 4 generated images. They are predictably formatted as follows:
	http://img.youtube.com/vi/<insert-youtube-video-id-here>/0.jpg
	http://img.youtube.com/vi/<insert-youtube-video-id-here>/1.jpg
	http://img.youtube.com/vi/<insert-youtube-video-id-here>/2.jpg
	http://img.youtube.com/vi/<insert-youtube-video-id-here>/3.jpg
	The first one in the list is a full size image and others are thumbnail images. The default thumbnail image (ie. one of 1.jpg, 2.jpg, 3.jpg) is:

	http://img.youtube.com/vi/<insert-youtube-video-id-here>/default.jpg
	For the high quality version of the thumbnail use a url similar to this:

	ffmpeg -y -i input.mp4 -vf fps=10,scale=716:-1:flags=lanczos,palettegen palette.png
	ffmpeg -i input.mp4 -i palette.png -filter_complex "fps=10,scale=716:-1:flags=lanczos[x];[x][1:v]paletteuse" output.gif
