FYI, after I my save file got corrupted I made a quick windows batch script to backup my saves. Then I added the batch call to my windows task scheduler on system start: Make a folder called backup in you ksp folder then create backup-save.bat somewhere and save the following into it with the appropriate paths: @echo off setlocal set rr=%DATE:/=%-%TIME::=% set rr=%rr:.=% xcopy /s/e/k/y C:\Users\UserName\Desktop\KSP_win\saves C:\Users\UserName\Desktop\KSP_win\backup\%rr%\
