The database is currently at 19.9 GiB, and it increases so slowly I haven't noticed anything :P.
I heard that Lemmy only stores text, and media is hosted only on the instance on which it’s uploaded on.
Depends on how you configure it, I have it only store media from my local users by setting image_mode: "None"
in lemmy.hjson (the config file), so that doesn't increase a lot. I use Exoscale as my object storage provider.
Regarding traffic usage, I can't tell you precisely because I use Cloudflare and that caches a lot of data. In the past 18 days there have been 108GB transferred from my VPS (data from Hetzner). These are the analytics from cloudflare:
btw if you plan on buying a Hetzner VPS it would be awesome if you used my referral link: https://hetzner.cloud/?ref=xNvN4vWKXSzw to get 20€ in credits for free, and I also get 10€ if you decide to buy something from them.
Thanks, I hate it
