How do i reduce github lfs bandwith usage in ci jobs?


I run github actions with self hosted runners on docker. Everything works wonderful but the CI jobs eat my git lfs bandwith. Is it possible to set up a hosted server which serves as a proxy to github by saving the files locally on the server and just if they don’t exist there github will be contacted? This could reduce my bandwith usage significantly. Are there any other options to solve this? I am sure this is a common problem which has a nice solution.
