I foolishly erased my SH setup, need to recover one remote session

Because of a bonehead move I erased my SH setup including my backups.
I have been able to recover all of my remote access computers except one. This computer is running a remote ham radio on a mountain top that is a 4 hour drive away over dirt roads.
Is there anything that can be done?
Here is my info:
My SH server is at w6ryo.com:585

Remote information:
SG_-6342606008864240600

I really don’t want to drive up the mountain if there is anything I can do from the ground.

thanks

I do not have any advice on how to wrangle in that last workstation back into your SH, but I do have a recommendation for going forward:

Depending on your setup, though (and how you handle any security policies), I would recommend installing a secondary/backup option on the machine (i.e. TeamViewer, etc.,), in case SH is not reachable for whatever reason.

Another option, if you have the space, is to place a secondary workstation up there - always on - on the same network, and of course has SH (and/or a redundant service, too) installed on it, and on both machines have a VNC option installed (e.g. UltraVNC) on both - server/client/viewer.

This way, in a similar or unresponsive situation, you can hopefully use the secondary computer that you can still get connected to, and then VNC over to the primary machine, and get things back up and running as you need. Potentially send a WOL to the computer, as well. If it somehow was powered off and not near the window of time, you may have it scheduled to power back on automatically.

Thanks for the response. It was just a hail Mary to save a drive. I did almost everything wrong and it was a learning lesson.
