Use RAID 0 if you want pure write speed and/or maximum capacity
for your disks, and/or you have other means of protecting your data.
Use RAID 1 if you have an even number of disks and want to mirror
primary data to another disk(s). Use RAID 5 if you have four disks and
you want to balance performance, hard disk capacity usage with data
protection. If one disk fails, replace it and then re-synchronize to
recover all data.
A snapshot is a backup of your NSA data on the NSA. If files within a
volume become infected or corrupted, you can revert the volume back
to a previous snapshot. It's a good idea to create a snapshot before
backing up data, to be sure you're backing up consistent data even if
the backup is still running several hours later.
Use the disk quota feature to stop one user(s) from using up all disk
capacity by setting a limit on how much storage space he/she may
use.
Configure a password for an individual User to restrict access to the
NSA. Non-admin users can change their own passwords by
accessing the web configurator. The Change Password screen
appears when a username other than "admin" is entered.
For Windows or Mac OSX users (using the Common Internet File
System (CIFS) protocol for remote file access) you can configure
Workgroup mode requiring users to log in with a user name and
password. These user and group accounts are maintained on the
NSA. For a large number of CIFS users where accounts are stored on
an external server, you can use Domain security mode (Primary
Domain Controller)
Data can be shared among all Windows, Mac, Linux, and UNIX users
that have FTP client software or CIFS file sharing support (such as
Samba for Linux and UNIX users).
Access the NSA using a regular web connection (HTTP) or an
encrypted web connection (HTTPS) using secure socket layer (SSL).
DHCP (Dynamic Host Configuration Protocol) allows the NSA to
obtain an IP address and subnet mask at start-up from a centralized
DHCP server. Alternatively, you can give the NSA a static IP address
and subnet mask.
The embedded web configurator is an platform-independent web-
based utility that allows you to easily access the NSA's management
settings.
Upload new firmware to the NSA using the web configurator. You can
also back up and restore the NSA configuration file containing all its
settings to/from your computer.
Use the NDU from a Windows computer to find NSA(s) in your
network, access the NSA login page, change its IP address
configuration or map to a Windows network drive.
Genie Backup Manager is a tool for Windows users to create (and
schedule) backups of data stored on their Windows computer to an
NSA.
Configure a time server and set a time zone for your NSA to show the
correct times in e-mail alerts and logs.
Configure an e-mail to be sent to an NSA administrator whenever an
error occurs or as a scheduled log summary.
