USB <-> NAS
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.

Synchronizing Files Example 2
A on the USB device and B on the NAS are modified more recently.
• File A from the USB device replaces file A on the NAS.
• File B from the NAS replaces file B on the USB device.
• A copy of file C from the USB device is transferred to the NAS.
• A copy of file D from the NAS is transferred to the USB device.
17.12 Syslog Server Screen
Use this screen to configure the NAS to accept syslog logs from syslog clients such as ZyXEL’s G-
4100 v2.
Note: You may need to configure any firewalls between the NAS and the syslog clients in
order to let the syslog traffic go to the NAS.
