What are the requirements of a server to run a Lemmy instance and there is a way to run like a node WO the need to have lots of storage available?
What are the requirements of a server to run a Lemmy instance and there is a way to run like a node WO the need to have lots of storage available?
Thx in advice.
I'd 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 you've federated with a community. And it's 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.
It's 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. I've got over a month before I have to worry about storage space at the rate I'm using it.
As for system requirements, as long as you're 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:

Federation is done per community?! Ok, this creates more questions:
Then why are instances defederating whole instances if they're 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 hassle... How does e.g. lemmy-world do it?
I am interested in this too. As far as I know, you don't store images or videos, so that should help keep it light. I can't image the requirements for storing a database and text to be high but I am no server admin.
I saw one of the instance admins post that they had about 400mb of new data to store each day but idk how accurate that is.
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.
You store what is in your instance, and some content of another instances, according to your instance settings (in Friendica you can control what is stored in your instance, how much in megabytes for cache...), but in general you only need storage for content that you follow, and a bit more for public timeline content, but is not needed a copy of the fediverse in your instance.
