[Question] Disk Space for Lemmy and Mastodon instances (self.selfhosted)

submitted 1 year ago by Solvena to c/selfhosted

Hi, I'm new with self-hosting but managed to set up my own Lemmy and Mastodon instances on a VPS recently. However, I ran into an issue with disk space quite rapidly (which I had way too few, because I started with the cheapest, smallest package for my VPS).

Now I prepare a new setup, where I'll be able to dynamically scale disk space as needed, but this can get expensive quickly. Therefor my question: How much disk space do I typically need for private (1-3 user) instances of Lemmy and Mastodon? Are there settings, where I can limit the disk space utilization (at the cost of older stored content being overwritten)?

I would be fine with needing up to like 30-40 GB, but any more than that would be getting kinda expensive ....

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).
