USB <-> NSA
When you synchronize files in both directions simultaneously, both storage devices
transfer unique files to one another. Files with the same file name are
synchronized according to their modification date/time. The difference in
modification time between the two files has to be greater than five minutes. More
recently modified files overwrite the older ones during synchronization.
The following figure illustrates how synchronization works when you synchronize
files in both directions simultaneously.
