[Question] Disk Space for Lemmy and Mastodon instances (lemmy.world)

submitted 1 year ago by [email protected] to c/[email protected]

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 ....

With Lemmy, it will depend more on the amount of media that your users upload than anything. With Mastodon, you also will have to consider the amount of data in the cache.

With Mastodon, I have (small) instances running for about an year or so which are using less than 100GB, and I have instances from power users that went on to take ~250GB in less than a month.

You can set up Mastodon to delete posts after a certain age and to clear the remote cache periodically. This would help mitigate both things.
