The following figure illustrates how synchronization works when you synchronize files from a USB
device to the NSA. The same concept applies when you synchronize files from the NSA to a USB
device.
Figure 133 Synchronizing Files Example 1
Both storage devices contain A.
• A copy of files A and B from the USB device is transferred to the NSA.
• File A from the USB device replaces file A on the NSA.
• File C on the NSA is deleted.
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.
