I have my AC all backed up on a portable drive after having my old laptop die a horrible smokey death and did it that way when I got a new laptop, lost nothing other than new files I had added since the backup was created.
my steam folder is installed on a seperate SSD into a folder named game. It includes all steam games I have plus CM installed there, so only backup needed to make is the one games folder, plus the assettocorsa folder in documents.
CM also stores data in C:\Users\
insert your username here\AppData\Local\AcTools Content Manager
