CHAPTER

Getting to Know Your NSA
1.1 NSA-2401 Overview
The NSA (Network Storage Appliance) allows secure storage and management of data on
your network. Windows, Apple, or Linux users can access data on it as if it was on their own
computers. The NSA’s two Gigabit Ethernet ports can connect to two different LANs. Users
on either LAN (or connected through the Internet) can back up and share data on the NSA.
Two USB ports let you share USB printers and use external USB hard drives for extra storage
space.
Figure 1 NSA Overview
• The NSA’s SATA II (Serial Advanced Technology Attachment) hard disk serial links are
compatible with all major hard drive manufacturers.
• RAID (Redundant Array of Independent Disks) protects your data even if a hard disk fails.
• The snapshot and backup features let you further protect your data.
• The NSA offers powerful security features. Use HTTPS or FTPS for secure file transfers.
Create encrypted volumes so an attacker who removes the physical drive still cannot read
the data. The NSA can also record all user access to files and folders.

Introducing the Web
Configurator
This chapter describes how to access the NSA Web Configurator and provides an overview of
its screens.
2.1 Web Configurator Overview
The Web Configurator is an HTML-based management interface that allows easy NSA setup
and management via Internet browser. Use Internet Explorer 6.0, Mozilla firefox 1.0,
Netscape Navigator 7.0 or later versions of these browsers. The recommended screen
resolution is 1024 by 768 pixels or higher.
In order to use the Web Configurator you need to allow JavaScripts.
2.2 Accessing the NSA Web Configurator
Make sure your NSA is properly connected (refer to the Quick Start Guide).
2.2.1 Access the NSA Using the NDU
If you don’t know the IP address of the NSA, then use the NDU to find it. Refer to the Quick
Start Guide to see how to install and run the NDU.

following table describes the ‘global’ icons and tabs in the user-level screens.
2.5 My NSA Screen
Use the My NSA screens to manage your shares and access the files in folders to which you
have access.
A share is a set of user access permissions for a specific folder on a volume (gives someone
access to a folder). It is similar to a shared folder in Windows, but the access rights are
independent of the folder (you configure the share and the folder separately). You can map a
share to a network drive for easy and familiar file transfer for Windows users.

• How to Configure Security: page 68
• Power Resume: page 89
• How to Use Backups and Snapshots: page 89
• How to Increase the NSA’s Storage Capacity: page 106
3.2 How to Configure Sharing
This section covers how to create user accounts, groups, and shares.
You can customize account permissions to give different users different levels of access to
individual files and folders hosted on the NSA. For example, if you intend to use the NSA
within a single department you may decide to give all the members of that department read
and write access to all the files located on it. You may also to give management read and write
access to some files and give other employees read-only access. Using the tools built into the
ZyXEL Web Configurator, you can do just this.
3.2.1 Setting Up User Accounts
As the administrator of the NSA, one of the first tasks you will want to do is set up accounts
for everyone who needs to use it. Suppose you need accounts for a vice president named
Gonzo and a manager named Kermit. Do the following to create a user account.

3.5.3 Controlling Access to Shares, Folders, and Files
Gonzo wants to give Kermit and the senior management group read-only access to the
Strategy folder. However Kermit is not to see the 2010-2014-Plans file. The following
sections show how to configure the “Gonzo” share’s access settings and Access Control List
(ACL) settings.
3.5.3.1 Configuring the Share’s Access

3.6 Power Resume
To keep the NSA operating as much of the time as possible, do the following to have the NSA
automatically restart when the power comes back on after a power failure.
Click Maintenance > Power Management. Select Always Power On and click Apply.
Figure 75 Maintenance > Power Management
3.7 How to Use Backups and Snapshots
Use the NSA’s backup and snapshot features to backup your files and folders.
• Do snapshots frequently (hourly or daily for example) since they are faster than backups.
Snapshots help protect against accidental file loss or damage caused by hackers.
• Schedule backups for times when the network is not busy (like at night or on weekends).
For example, you might do daily backups of important individual files or folders and a
weekly general archive. You can save backups to another location so your files can
survive even if the original RAID or NSA fails.
Chapter 3 Tutorials
NSA-2401 User’s Guide
90
3.7.1 Creating a Snapshot Job
Here’s an example of configuring hourly snapshots for a volume.
1 Click Protect > Snapshot > Add Job.
Figure 76 Protect > Snapshot
Chapter 3 Tutorials
NSA-2401 User’s Guide
91
2 Enter a name for the job, select the volume of which to take snapshots, set the number of
snapshot images to keep (2 in this example). For the frequency, set it to occur every
hour. Click Apply.
"
It’s strongly recommended to set the maximum amount of snapshots setting
as low as possible as a high amount of snapshots can significantly reduce the
volume’s file write performance.
Figure 77 Protect > Snapshot > Add Job
3.7.2 Configuring Snapshot Image Access
Taking a snapshot creates an image file that you use to restore files. By default, only the
administrator can access the snapshot images. You want to allow users to access snapshot
images in the shares that they use.
Click Protect > Snapshot > Snapshot Image Access to open the following screen. Then
select User Share Permissions and click Apply.
Figure 78 Protect > Snapshot > Snapshot Image Access
3.7.3 Using a Snapshot Image to Restore Files
To use a snapshot to restore files, use the MyNSA screens, CIFS (Windows Explorer), or FTP
to browse to the folder named “snap-share”. Open or copy the folder or file that you want to
restore.
Chapter 3 Tutorials
NSA-2401 User’s Guide
92
For example, Gonzo accidently overwrote his 2009-Plan.doc file.
Use Windows Explorer to browse to the Gonzo share. (The Quick Start Guide covers how to
map a share to a Windows network drive).
Figure 79 Using a Snapshot Image
• There is a snap-share folder with a folder for each snap-shot of volume contents to which
Gonzo has access. A snap-shot folder’s name identifies the take number of the individual
snapshot, the time the snapshot was taken (in year month, day, hour, minute, second
format) and the name of the snapshot job.
• The take4_080904160008_hourly_example folder contains a 5yearPlan folder with a
2009-Plan.doc file. Gonzo can open the 2009-Plan.doc file or copy it to another location.
3.7.4 Creating a Synchronization Backup
Gonzo has an important folder that the German branch office uses on a daily basis. Because
Gonzo updates the files frequently, you decide to create a backup job that has the NSA publish
the contents of the folder to an NSA in the German branch office. To create a synchronization
backup:
1 Click Protect > Backup > Add Job.
Figure 80 Protect > Backup
Chapter 3 Tutorials
NSA-2401 User’s Guide
93
2 Name the backup job and select Synchronization.
Gonzo wants only his current set of files in the remote NSA’s folder, so you select
Mirror to make the target folder identical to the source folder. The NSA deletes any
other files in the target folder.
Figure 81 Protect > Backup > Add Job: Step 1
Chapter 3 Tutorials
NSA-2401 User’s Guide
94
3 Select the folder that needs to be mirrored (the Gonzo share’s Strategic-Partners folder
in this example) and Remote.
• Enter the other NSA’s address and administrator password.
• Click Show target content to display the remote NSA’s contents.
• Select the destination on the remote NSA (Backups in this example).
• Click Next.
Figure 82 Protect > Backup > Add Job: Step 2
Chapter 3 Tutorials
NSA-2401 User’s Guide
95
4 Click OK in the warning dialog box.
Figure 83 Protect > Backup > Add Job: Step 3
5 For this example, assume the connection to the German branch office is a good one and
not many files need to be backed up so leave the compression off.
• Turn on the encryption to protect these sensitive files during the transfer. The final
files stored on the remote NSA will be unencrypted (usable).
• Restrict the bandwidth usage to 256 KB/s to stop the archives from using all of your
network connection’s available bandwidth.
• You don’t have to configure a purge policy for a synchronization backup.
• Click Next.
Figure 84 Protect > Backup > Add Job: Step 3
Chapter 3 Tutorials
NSA-2401 User’s Guide
96
6 Schedule the backup to occur every morning at 3:00 and click Done.
Figure 85 Protect > Backup > Add Job: Step 4
You do not need to use a special restore process to use the files a synchronization backup
creates. The copy of files that the NSA creates on the other NSA’s Backups share can be used
directly by anyone with access to that share.
3.7.5 Creating an Archive Backup
To backup the NSA every week to a remote NSA:
1 Click Protect > Backup > Add Job.
Figure 86 Protect > Backup
Chapter 3 Tutorials
NSA-2401 User’s Guide
97
2 Identify the backup job and select Archive.
New files are often added to the shares that you need to back up and existing files are not
frequently changed so select Incremental. The NSA does a full backup first and later
only copies source files that are new and/or modified since the last backup. This example
sets the NSA to do another full backup after every four incremental backups.
Figure 87 Protect > Backup > Add Job: Step 1
Chapter 3 Tutorials
NSA-2401 User’s Guide
98
3 Select the volume1 check box to select all the folders and files.
Select Remote and enter the other NSA’s address, username, password, and share name.
If you want to make sure the remote NSA is reachable, click Test Connection.
Figure 88 Protect > Backup > Add Job: Step 2
Chapter 3 Tutorials
NSA-2401 User’s Guide
99
4 In this example, the target NSA is on the LAN so leave the compression off.
Security is already configured on the target NSA so you can leave the encryption off,
too.
Have the NSA keep 3 backups.
Figure 89 Protect > Backup > Add Job: Step 3
5 Set the frequency to Weekly. Schedule the backup for 5:00 every Saturday morning.
Figure 90 Protect > Backup > Add Job: Step 4
3.7.6 Restoring Archived Files by Backup Job
If you have backup jobs for which the NSA has already performed backups, you can restore
the files based on the backup job. Gonzo accidently deleted all of the files in his share and
needs to do the following to restore them.
