My instance increases by 1GB per day (lemmy.ml)

hello, on my server on which only Lemmy is running, I don't understand why it fills up space all the time. Every day it increases by about 1GB thus risking reaching the limit after a short time.

It is not the images' fault because there is a size limit for uploading and they are also transformed into .webp.

The docker-compose file is the one from Ansible 0.18.2 with the limits for loggin already in it (max-size 50m, max-file 4).

What could it be? Is there anything in particular that I can check?

Thanks!

Bearing in mind that posts and comments from communities your users are subscribed to will flow into your instance, not as a reference, but as a copy. So all those “seeding” scripts are terrible ideas in bringing in content you don’t care about and filling up space for the heck of it. If you’re hosting a private instance, you can unsubscribe from things that won’t interest you, thereby slow down the accumulation of contents that are irrelevant and just wasting space.

Yes I had considered that, but considering that ours is not a giant but moderate instance (a thousand subscribers) it seemed exaggerated to get to have 1GB occupied every day.

The growth is not about user count... not directly anyway. Rather, it's about the number and activity of subscribed communities. When your users sub to big and highly active meme communities on Lemmy world, the post activity on world determines your storage reqs. I don't really know, but I could imagine that a 1k user instance might have 80% of the federation storage that a 5k user instance has. 1k users is enough to sub most big communities, whereas the next 4k users are "mostly" going to sub the same big communities and a few low-traffic niche communities. So the next 4k users cause much less federated storage load than the first 1k did.
But for comparison, a month ago... the largest Lemmy instance in the world had just over a thousand active users. I'm not sure 1k is as small as you think it is.

Not to mention the added load to all the servers that are sending you crap you don't even look at.
