How quickly will a lemmy instance eat up storage?

Just started self hosting this instance. Nothing on the docs mentioned anything about storage considerations.

Do you also post stuff? I mean my instance is only about an hour old, but I've subscribed to some communities, yet I don't see the picture service consuming the S3 storage I've configured

Lemmy caches every thumbnail of every post for like a month or something using Pictrs, so that storage will eventually hit a sort of equilibrium and start growing much more slowly (only reflecting post/thumbnail volume during the cache time).

Between profile images, community banners/icons, post images etc. there are probably a few dozen images that will be sticking around for the long haul at the moment.

Your instance only caches thumbnails, so it won't take much space. The full images are served from the remote instance. So you basically only store whatever your users upload.
