When I first new about lemmy, lemm.ee was among the biggest and I created an account on it but didn’t use it much and didn’t knew that the instance was deleted until recently. So help me understand where content is stored:
-
When a post is created, is it only stored on the original instance, or copied to every other one?
-
Do all federated servers get a copy, or get posts from other server when user demands them?
-
When an instance shuts down, is its content gone forever, or do other instances keep copies?
-
If the original server is gone, what happens to edits or deletions?
-
Is there any kind of “shared” storage in the Fediverse, or network that store everything?
-
Could one still access all lemm.ee content now? Or post in it’s communities?
I don’t know all the details, but it looks like every federated server will save its own copy of the now-deleted server’s posts in its archives. Here’s a post from lemm.ee that’s still visible on Hexbear as an example. Given this knowledge, I bet you could recreate lemm.ee with a script that gets the data from all of the servers it was federated with.
