I am the admin of the newly created instance https://indie-ver.se/, and it's been going great. But as I was looking to migrate all images to a S3 bucket, I noticed, the images take up more space than I had anticipated, a bit over 1 GB. And I know for a fact, that there has not been many images uploaded to this instance directly.

My best guess is, that it's because lemmy by default creates local thumbnails for external posts, via. the setting "image_mode: StoreLinkPreviews". Lemmy does allow me to disable this behavior, i.e. it would not cache the thumbnails on my instance, and instead have browsers request the image from the other instances.

The question is, what impact would that have on my users, and what impact would it have on the fedi-verse in general? I believe it would save me a lot on future storage costs, but I don't know if it's worth it.

I just set up our S3 image storage, which costs us 6.27€ pr. TB. (with Hetzner)

Actually, how do you backup your images? I am bit unsure of what to do here, since the objects aren't really managed by me.

From how you describe your context (similar to mine), you don't seem to need to backup images. Few local images mean little impact of possible failures.
