Just started self hosting this instance. Nothing on the docs mentioned anything about storage considerations.

        im running 50 users right now, subbed to A LOT of communities, seeing db growth of about 100mb per day.

            It’s all about how many communities your user(s) subscribe to since your instance basically acts as a mirror for those.

            My instance has been running for 23 days, and I am pretty much the only active local user:

            7.3G    pictrs
            5.3G    postgres
            

            edit: I may have a slight Reddit Lemmy problem

              So if you’re the only user (let’s assume for ease) then, that represents all the updates (posts, comments, votes) from each community that you are subscribed to?

                Yeah, and I purposely subscribe to (or sometimes have a dedicated “federation helper bot” account I run subscribe to) most of the most popular communities on the most popular instances so I can get a decent sampling of what’s going on in the fediverse on the “All” feed. So I assume my storage usage is maybe a bit higher than what an “average” single-user instance may be…

              Do you also post stuff? I mean my instance is only about an hour old, but I’ve subscribed to some communities, yet I don’t see the picture service consuming the S3 storage I’ve configured

                Lemmy caches every thumbnail of every post for like a month or something using Pictrs, so that storage will eventually hit a sort of equilibrium and start growing much more slowly (only reflecting post/thumbnail volume during the cache time).

                Between profile images, community banners/icons, post images etc. there are probably a few dozen images that will be sticking around for the long haul at the moment.

                Your instance only caches thumbnails, so it won’t take much space. The full images are served from the remote instance. So you basically only store whatever your users upload.

            It won’t scale linearly. A lot of those users will be subscribed to subs the instance is already replicating. It would only be new subs that would add to the growth.

        Question if you know: does a lemmy instance have to be publically accessable to work? Like, if I make an instance on my homelab can the instance “fetch” content and serve it faster locally? Could I reply to a post and have others see it? Etc

        At the end of the day the vast majority of what needs to be saved is text. If media content is embedded, the the server just has to save the path to the file not the file itself.

      Feels like this will benefit from some sort of fuzzy deduplication in the pictrs storage. I bet there are a lot of similar pics in there. E.g. if one pic or a gif is very similar to another, say just different quality or size, or compression, it should keep only one copy. It might already do this for the same files uploaded by different people as those can be compared trivially via hashing, but I doubt it does similarity based deduplication.

      I really hope it doesn’t get purged if lemmy is to be a Reddit replacement. A lot of the value Reddit had was obscure knowledge and making google searches actually usable.

        I think as long as the original community the post is in doesn’t purge the data, it’s fine for other instances to purge if necessary.

          Exactly, when dealing with big data, you need a strategy to archive old data. You can’t just store everything in one DB. Smaller instances may not feel like keeping all the date from all the time. Even big instances should have a mechanism to move old data do different databases.

    Depends. If you have a lot of users posting a lot of pictures and you use pictrs out of the box config, then a lot. If you are just running a few users with finite communities being synced then a lot less. The number is going to vary a lot as lemmy grows and gets older so hard to document realistic expectations. But docker images are probably going to take up more disk space than actual contents unless you get quite big. I just threw my PG volume into a tgz to move servers and it’s less than a gig.

    Unless they changed all of the comment and post ids to bigints that’ll probably bring the site down before it runs out of storage. In defense of the lemmy developers they have been receptive to feedback, so I don’t think it’ll take long for that to be fixed if it hasn’t already.

    My instance eats up almost 100MB everyday. It mostly depends on what your users subscribe to. It was barely growing on my first few days until I invited a couple of friends over to try it out.

    My instance dormi.zone has been running for around 3½ weeks now, has a 3-digit amount of users and hosts a community with little more than 1000 subscribers. Here’s how much storage it currently takes up:

    • 6.2 GiB postgres
    • 4.9 GiB pictrs

    In the default Ansible configuration, storage will mostly be accumulated by log files that are automatically generated by Docker and deleted whenever you restart the Docker containers.

    I haven’t tried it out just yet, but I’d say… a whole lot. Depending of how popular your instance is, but… your PC will be hammered in any way.
