Thx in advice.
Iโd like to know that too. Do I have to mirror the whole fediverse in my personal instance?
Your instance will only clone new content after youโve federated with a community. And itโs per community, not per instance.
It will also be generating thumbnails for websites that are linked, and a good chunk of the data requirement goes here.
I can tell you that, on average, my instance consumes about 700MB per day. I could cut that down if I federated with less communities, and I could get it down to 400-500MB per day (probably less) if I blocked my instance from generating thumbnails.
Itโs not a lot, but over time it will add up. My instance is pretty new, and I have no idea what pruning options are available yet. Iโve got over a month before I have to worry about storage space at the rate Iโm using it.
As for system requirements, as long as youโre not supporting users besides yourself, Lemmy will pretty much run on a potato.
TL;DR
- 400-700MB new data per day depending on your usage habits
- Whatever you want to run it on will probably be fine
EDIT: Turns out ~90% of my Lemmy data is just for debugging and not needed:

Thatโs it, I think some political people need their own potato! Put them on an island and the only contact they have is liking their own comments and postsโฆ
Federation is done per community?! Ok, this creates more questions:
Then why are instances defederating whole instances if theyโre unhappy with the content of specific communities?
And more on topic: What about new communities? Do you need to manually federate with need communities on an instance? This seems like a hassleโฆ How does e.g. lemmy-world do it?
Then why are instances defederating whole instances
That requires a little less tl;dr. What they were talking about was in regards to populating your feed with content from other lemmy/kbin servers communities. Thatโs one part of the federation going on behind the scenes. The other part is that lemmy servers are usually set up so they can federate with whomever by-default , just that they canโt know about any other lemmy server out there unless a user on that server specifically finds a community on another server and interacts there in some way. From then on they are federating server to server through those communities. The two are loosely related
The reason for the recent defederations from lemmy.world and sh.itjust.works servers were due to bad actors (read trolls and hate speech) from those servers according to the behaw.org server admin. It could have been taken care of through moderator actions on the affected communities or by banning the bad-actors from behaw.org by the server admins, but the current lack of mod tools and lack of manpower of the mods there would be too much to take care of. The options for deferation on lemmy right now arenโt very fine-grained, so it was either tons of work on the moderation side trying to keep the beehaw communities safe for their users, or the nuclear option of defederation, which is what they ended up going with.
Feel like this is a bit long winded, but I hope Iโve helped clarify it a little at least.
Back in the day at least on Mastodon you can keep your instance unfederated, but I donโt know about Lemmy, it would be good some Lemmy project admins advice here.
Truth.social (Trumpโs social network thing) is an unfederated Mastodon. Basically, your instance is an island, but a fully functional island.
Lemmy uses roughly 150 MB of RAM in the default Docker installation. CPU usage is negligible.

As for storage that comes down to how many communities you subscribe to, and how active they are.
I am interested in this too. As far as I know, you donโt store images or videos, so that should help keep it light. I canโt image the requirements for storing a database and text to be high but I am no server admin.
