I have a related question. I want to take backup of certain folders to a portable USB HDD every night. Can anyone recommend any simple solution for that? I don't need encryption or any extraneous features. I just need the selected directories to get mirrored to a backup location. Currently, I am using SyncToy by Microsoft, but I was looking for a cross platform solution.
