7.8.2 Synchronizing Files
Synchronization makes the contents on the target device identical to the ones on
the source device. You can synchronize files from a USB device to the NSA or from
the NSA to a USB device. In addition, you may also synchronize files in both
directions simultaneously.
Press and hold the COPY/SYNC button until you hear a beep to synchronize files.
See Section 7.8.3 on page 167 for details about configuring the synchronization
settings.
USB -> NSA or USB <- NSA
When you synchronize files in one direction, contents on the source device replace
the files on the target device.
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.
