I keep a homeserver for long term bulk data storage, emphasizing things that benefit my extended circle of friends and family and that would be impossible to acquire physically. Film editions out of circulation or only at a premium, quality cookbooks, reputable guides to household repair and craft, niche trade and hobbyist materials, rips of CDs from indie scene shows, political theory texts that would be difficult or someday potentially dangerous to get through the public library (hello, marxist internet archive, and thank you). A number of older games and software titles, too. It is increasingly difficult and costly to get permanent access to essential practical and cultural works, and while keeping up a dependable archive is sometimes a chore, I anticipate the work will prove worthwhile in the not so distant future.
