Remember to keep a local offline mirror of your favorite content from ripped physical media, online archives and aggregators. Rotate every 5 years to larger, newer drives that can store higher-resolution versions. Nothing is infallible, including archive.org, infocon.org, flickr, github/gitlab/sourceforge, YT/peertube/rumble, kiwix/stackoverflow/wikipedia and long-tail niche websites.
