Thx in advice.
I’d like to know that too. Do I have to mirror the whole fediverse in my personal instance?
Back in the day at least on Mastodon you can keep your instance unfederated, but I don’t know about Lemmy, it would be good some Lemmy project admins advice here.
If you’re unfederated, doesn’t that mean you can’t see anything?
Truth.social (Trump’s social network thing) is an unfederated Mastodon. Basically, your instance is an island, but a fully functional island.
Oh i never knew that. And I thought they created their own code…
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:

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.
