My kbin instance’s data (text data, that is) probably takes up less than 8 GB right now, and I’ve had it running about two weeks. Media storage (which I do through S3) is around 5 GB so far. Kbin does do media mirroring different than Lemmy though (I think), so YMMV. I think Lemmy mostly links to the original instance’s media object as the source.

The main thing I found eating storage on my server was a lot of old Docker images (and volumes) from me trying to get everything up and running. If you are using Docker you could try doing a docker system prune --all to get rid of unused images/build caches (anything that isn’t running currently).
