NSA-2400 User’s Guide
23 Chapter 1 Getting to Know Your NSA
RAID File Storage
Use RAID 0
1
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.
Snapshot
2
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.
Disk Quota
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.
User Passwords
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.
Workgroup and Domain Security Modes
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)
Client Support
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).
HTTP/HTTPS
Access the NSA using a regular web connection (HTTP) or an encrypted web connection
(HTTPS) using secure socket layer (SSL).
