To answer your questions first:
"Do I need to install a BlackArmor Software?"
You do not need to install on your client workstations the BlackArmor "Backup" software that comes with the NAS if you plan to use Symantec Backup Exec 2010. - Note: In your next question I see you are using a Small Business Windows Server. In fact the included Blackarmor Backup software will not even install on a server it will only work on a Windows XP, Vista and/or Windows 7 Workstation only. It is recommended though that you do install on each client workstation the BlackArmor "Discovery" software.
Do I need an optional agent (using a single small business windows server)?
No additional agent is needed.
To configure Symantec Backup Exec 2010 -
1) First get the NAS on your network following the User Guide.
I prefer using Static IP Addressing myself, and I suggest putting the NAS into it's own Workgroup as it does cause problems with the Browser function of the "Network Neighborhood" for other devices that may belong to the same Workgroup as it. Keeping it isolated in it's own little world solves that problem, you'll still be able to see the device via "Network Neighborhood" as well it will be listed under it's own workgroup.
2) Access the NAS's Management Web Page via a workstations "Browser" that's connected to the same network as the NAS using http:\\ip.address.of.nas
3) Follow the Guide on creating a "SHARE" (either Public or Private)
Public is less of a hassle if you don't have security concerns on your local network.
Private you'll have to also create a User Account on the NAS as well.
4) Set the SHARE that you just created to support CIFS you don't need to set FTP or NFS unless of course you wish to access the share using that as well. (Using CIFS your Windows Small Business Server will not need any "agents" installed)
5) Open Windows Explorer on your Small Business Server and Choose Map Network Drive.
6) Enter the UNC to your created share on the NAS that would be something like this \\nasname\sharename where "nasname" is the assigned name that you gave your NAS device during it's setup and "sharename" is the name that you assigned to the share that you created on the NAS. For example: if my NAS was named BAnas and I created a Share calling it SBSBackup I would enter: \\BAnas\SBSBackup also Pick any free drive letter to assign the mapping to.
7) Choose "Reconnect at Logon"
8) DO NOT Choose Connect using a different user name.
9) Hit OK - you'll be then prompted for credentials that is if you have set your share to "Private". If so enter nasname\userid and the password. For example if my NAS was named BAnas and I created an account on the NAS called SBSid which I had assigned to the sharename being mapped - I would enter: BAnas\SBSid along with the password assigned. Make sure that you Check the box to remember password.
10) Symantec Backup Exec 2010 does support backing up to a NAS but you need to do it like this:
You need to create a backup to disk folder that is pointed to the NAS via an UNC path as well again [ \\nasname\sharename ] this is done in the Devices section of BackupExec. Then in your backup job, you will point to the backup to disk folder that you just created that points to the UNC.
Cheers
