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!
