How much storage is used on average for a Lemmy instance? (lemmy.world)

If I were to create my own instance federated with all the other instances, as of today, how much data would I be storing, since I would make a copy of all the content?

I know this will vary a lot, but I’m looking for a ballpark figure to have an idea. I don’t think it would be a lot, but I can’t find an estimate anywhere.

it's my understanding that you won't make a full copy of everything. you'll only copy the communities that are added and you won't be copying the full history.

I'm unsure how far back it goes but it might be just the one day. i saw talk of changing it to go back as far as someone actually scrolled and pressed next but that was just an idea at this point.

Also it doesn't copy the images as Mastodon does, only the text objects.

For this reason, I assume it should be feasible to self-host an instance that sync with most communities.

For reference, Wikipedia (en) takes up just over 20 GB (https://en.wikipedia.org/wiki/Wikipedia:Size_of_Wikipedia), so I assume much less than that for Lemmy (with the current userbase).

oh right, that's a big one there. that images stay on the origin instance and they linked from there

I actually kind of like how Akkoma does this. It creates a constant size proxy with nginx, and all the images come from predetermined host instead of all over the net. It's a good mixture of not using tens of gigabytes of space and still spreading the load a bit between the instances.

Okay, I see, thanks.

But for example, do we know how much data lemmy.ml stores?
