I’m currently running both a home server and a VPS. The former is not reachable through the internet, only through vpn. The latter hosts public services.

The VPS is regularly cutting it very close with storage and today I messed up and crashed the whole stack trying to make an impromptu backup. Lesson learned: we need more storage! I could just rent more storage but just today I updated my home server with 16 TB of raid 1 enterprise HDDs.

So I thought I could maybe do a (wireguard) VPN tunnel directly to some storage service that I host on my homeserver. The upload is not great but realistically I dont need much. The important stuff stays on the VPS. Mainly videos, pictures and other stuff that doesnt get accessed a lot should go there. The rest should be “cached” at the VPS.

I would have to host wireguard on a server port, only have it access one folder which doesnt contain anything important, forward the port on the router and have the vps have the keys. Even if someone gets into the VPS and steals the keys, they only get that one file storage folder.

Has anyone done this? Are there services that do this or do I just host wireguard and thats it?

Thanks for reading. Have a good one! :)

    My solution is to use Rathole. I rent a wildly cheap (2 core, 4GB memory) VPS and basically just run Traefik there. Then I use Rathole to make some services hosted on my desktop available to Traefik.

    I like this solution better than Wireguard for my application. It reduces attack surface to services you’ve explicitly set up, rather than a full data layer trunk between your machine and a potential malicious actor.
