So I’ve been playing Icarus with the wife and the optimization is hot garbage. Wife is hosting and pulling 10 fps with a Nvidia 3070TI
We enjoy the game so I start doing research. Turns out once you’ve played enough the database on the host just gets too big and chokes out the CPU threads since it can’t use more than 2 cores.
Answer is to migrate your world to a sepf hosted dedicated server. Say no more.
So now I got an excuse (wife approved) to setup a computer as a server and keep it running. I have an old HP SFF i5 16GB RAM with an SSD I’ve reimagined a few times for a home server.
Flashed it with Debian and setup the Icarus server in docker. Runs like a champ.
Bonus points. I hooked up a wattage meter and it idles at 1~2 watts!
I used to run an old gaming computer as a home server and it felt like $30 a month in electricity.
Edit: System idles at 19 watts. I had the meter plugged into the wrong device…
Now I can start throwing more stuff on there once I figure out backup for the game world incase I bork it.


Step 1. Find out where the docker image you run saves the volumes
F.e. https://github.com/mornedhels/icarus-server saves here:
Volumes
Volume Description
/home/icarus/drive_c/icarus Server config files and saves
/opt/icarus Game files (steam download path)
Step 2. Find a backup tool you like, f.e. https://docs.borgui.com/
Thanks for mentioning the game, saved it to my wishlist and hope to grab it for some co-op gaming come autumn. :D
That’s! Once I get backups going I can rest my mind since I can avoid an angry wife. She’s the builder and if we lose our house…
Icarus is a little pricey but we both have hundreds of hours of playtime now. Worth it.
Takes a long time to level up but that’s not bad since you slowly learn more about the game as you unlock stuff.
Main tip is to start open world and then do missions from open world.
Its confusing since you need to level up a bit before you can build the contact device to even accept missions!
If you don’t start open world you need to restart your world every mission and that takes time.
So…
I want to backup the data and replicate a rebuild on a separate machine. Updated config to point to a better location.
My goal is to be able to rebuild completely from a failed disk. So restore backup to staged location then run the docker config to spin up all my stuff again.
Borg looks good!
