Default [Q][SOURCE-Related] Syncing ROM Source on Fedora 20

Hello all,I just wanna ask that can I sync a ROMs source in Fedora 20 host machine?I once synced Carbon's ROM source on Ubuntu 14.04 virtual machine but I was unable to take a backup of that source on my host via any shared folder or drag and drop technique.So I just wanna directly sync the ROM source on my host so as to keep it as a backup which would be helpful for compiling for other phones in future purposes.Is there any possible way?
Press Thanks If helped!
