Stop the service that’s doing the thing causing you a problem.
Fix the thing you screwed up
Restart the fixed service that was causing the problem
What could possibly go wrong?
In this case, and I’m making wild assumptions because I don’t have a peertube instance to play with, stop peertube, connect your local system up to it with a vpn to traverse your nat, mount some volume in the local system as the remote systems target for the file system move, then start peertube back up and see if it starts filling your local drive with some data.
When I made the wrong command, the application registered hundreds of move jobs in its database. The developer said there is no way to cancel the jobs. If I restart peertube.service then it will notice the incomplete jobs and immediately resume them. I think I'm going to use btrfs next time so I can take a system snapshot before executing risky server commands.

I need a little more detail on this. Here's my takeaway:
Host an (e.g.) OpenVPN server on the webserver, after creating the proper certificate infrastructure.
Connect as client from home PC.
VPN Success. Now I can access each other on the local subnet that starts with a 10. or something.
