NSA-2400 User’s Guide

This chapter compares the different ways of protecting data on the NSA-2400 and explains 
how to use the Protect screens to create and schedule snapshots and external backups.

There are a variety of ways to protect your data on the NSA-2400. Below is a summary table 
of what can be done in each situation.

The following sections describe these methods in more detail. See 

 for 

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. 

If you forgot the NSA password, then reset the device to go back to the factory default 
configuration.
