For me it would be a full copy of wikipedia, an offline copy of some maps of where I live, some linux ISO’s, and a lot of entertainment media.

    All the images I have bookmarked on multiple devices from e621, any game I’ve been even possibly hesitating on pirating, all my Steam games (I don’t trust Inwouldnhe able to get in and install them if I could even get into my account to begin with at that point), and downloading every single song I have saved on yt and Newpipe because I’d never see them again.

    A whole slew of things.

    Nothing.

    If the Internet went away, we’d have a little time before batteries we’re not viable even if replaceable, as distributing those batteries would get problematic.

    We would have had no time to withdraw cash as cash, an important thing since banks will fall over at least enough to trigger an economic collapse.

    No, we’re all gonna need to learn how to fight, and live without hospitals and drugs and probably electricity.

    We have bigger problems than ensuring we can look up the capital of Rwanda on this cached Wikipedia while we listen to The Cure.

      I could honestly just re-watch most of my shows until the end of time.

      I will literally never get tired of Bee and Puppycat.

    A full copy of Stack Overflow. Otherwise, we would not know how to get the Internet working again.

    I do have a copy of wikipedia and I should be good on entertainment media. I guess I should expand the emergency porn stash.

      Just out of curiosity, how much space/effort was that to set up? (Yes, I know I can probably google up like a bajillion resources on this exact thing, but I’m a weirdo and am attempting to bring the (non-toxic/shitty) social back to social media)

      I’ve been considering setting myself up a little NAS server since I finally dumped Spotify and am considering doing the same with video streaming too (besides Tubi, anyway), but having one just for mp3/light video streaming seems like a bit of a waste and having local repos of useful sites might be a fun side project to help justify it to myself lol

        I went with a Synology NAS (I know, the foss crowd will probably crucify me) which really keeps the setup effort to a minimum. You put in the HDDs, setup your pool/volume, install Plex (or jellyfin), upload your media and you’re basically good to go.

        I’m using emby for music, audiobooks, tv, and movies. You can also do picture backup/sync if you want. I am running it in a docker on my unraid server.

        For the Wikipedia part, it’s surprisingly simple. I just used Kiwix and grabbed a copy, it’s only about 100gb or so. You can also use it to get offline copies of other stuff, like Project Gutenberg.

    If you’d download the whole wikipedia be sure to download the whole commets section for each article to have a perspective on discussions on conflicting reasons for edits. Also include all the wiki media materials for all of the public domain literature, project gutenberg, entire archive.org, a good offline OS to be able to consume all of the information and you’re golden

        Let’s assume you have all hard drives and in a setup with absolutely zero redundancy in case a drive fails.

        We’re using the Seagate Exos X24 (24TB) drive which is roughly $700 each brand new.

        You’ll need 4167 of them to store 100PB. Which puts you at $2,916,900 just for the drives.

        Let’s assume you already have the enclosures, racks, and servers for a small datacenter ready to go.

        A drive can use 4-9w of power when spinning so assuming all drives are active (to ensure quick data access and data repair) that’ll be roughly 27086w for all the drives at 6.5w per drive. Every month (30 days), that is 19502kWh of electricity used. 40 years is roughly 349,680 hours so that comes out to around 9,471,433kWh used.

        Assuming you get some damn good electricity rates at $0.12USD per kWh, it’ll cost $1,136,572 to run just the drives.

        So in total, assuming you already have a datacenter with the capacity to install all the drives that runs on absolutely zero power, you’ll spend roughly $4,053,472 over the course of 40 years.

          There is a much cheaper way that doesn’t use hard drives. It uses magnetic tapes, LTO-9 tapes specifically.

          Each LTO-9 tape cassette can hold up to 45TB of data (compression is used to store it on the raw 18TB).

          An LTO-9 tape drive can cost $10,000. Assuming you get the full 45TB per tape, you’ll need 2223 LTO-9 tape cassettes to store 100PB. Assuming you buy in bulk, you can get each tape cassette for $150 which puts you at $333,450 for the tapes.

          Since the tapes don’t use power when not in use, this concludes the total cost. None of this accounts for storing all 2223 tapes or maintenance to ensure data is still intact on them but this comes out to $343,450 in total to store 100PB using magnetic tapes. While the cost is much cheaper, it’s much harder to access the data as it’s not immediately available since you have to fish out the drive you need and plop it into the tape drive then wait for it to read.

        You mean electricity bills for powering the storage? I guess buying 100pb worth of storage disks would be pretty expensive enough but since it’s an archive there is no need to keep it powered 24/7, just turn them on only when you need to. It’s just a hypothetical situation anyway, it’s a thing I wish to have access to; only an experienced sysadmin can actually maintain such great archive or its copy/backup
