Chapter 9 Protect Screens

NSA-2401 User’s Guide

• Use  the  Backup screens (

) to back up data and restore backup files 

by archive backup job.

• Use the Restore screens (

) to restore by backup files.

• Use the Snapshot screens (

) to create and manage snapshot jobs.

• Use the Backup Software screen (

) to locate the Genie Backup 

Manager license keys. 

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.

Configuration File Backup and Restoration does not affect disk arrays, 
volumes, or data (your files and folders) on the NSA.

Use the Genie Backup Manager to transfer data from your computer to the NSA. You could 
use Genie Backup Manager to back up from one NSA to another NSA but it’s recommended 
you use the NSA Protect > Backup to do this (see 

) as the latter 

would be faster. 

"

The Genie Backup program uses the same network port as the NDU to 
discover the NSA. To avoid a port conflict, do not run the Genie Backup 
Manager at the same time as the NDU.

A snapshot is a record of changes to an internal volume at a particular moment in time. As it 
only records changes to files made in a volume, it’s faster and takes up less space than a 
backup. Snapshots are good for data that changes often and needs to have high availability. If 
files within a volume become infected or corrupted, you can revert files back to their state at a 
snapshot.

You create snapshots of a complete volume, not a single file or folder within a volume.
