Media Server User’s Guide

This chapter compares the different ways of protecting data on the NSA and explains how to use 
backup management software included on the CD.

There are a variety of ways to protect your data on the NSA. Below is a summary table of what can 
be done in each situation.

The following sections describe these methods in more detail. See 

more information on RAID.

Use the Maintenance > Configuration menus to create a file of your NSA configurations such as 
passwords, shares and volumes created, network settings and so on. If you’re going to do some 
major configuration changes, then it is advisable to create a configuration backup file. If things go 
wrong after you make the configuration changes, you can always go back to the previous 
configuration by restoring an earlier configuration file. 

Overview of Protection Methods

Unexpected NSA behavior after configuration 
changes 

Back up the NSA configuration file before you make 
major configuration changes.

Need to transfer data from your computer to the 
NSA after volume(s) have been created

Backup your data to a computer or other storage 
devices.

Data infected by virus

Use anti-virus software on your computer to scan files 
before saving them onto the NSA. Although this may be 
slow so you may want to schedule it to occur while no 
one is using the NSA.

Use a firewall with anti-virus capability on your network.

Hard drive malfunction.

Use RAID.

NSA malfunction 

Network down

Natural disaster such as a fire or earthquake occurs 
where your NSA is located

Back up data to another NSA or external USB hard 
drive.
