Single datacenter with standard NetBackup
A single datacenter with standard NetBackup is defined as a medium to large group of hosts (greater than 50). It includes the hosts that are both internal only and those that expand through the DMZ to the Internet. This configuration typically has centralized naming service for hosts (such as DNS or WINS). It also has a centralized naming service for users (such as NIS or Active Directory).
The single datacenter with standard NetBackup includes the following highlights:
Externally facing hosts
Centralized naming services typically exist
Greater than 50 hosts in size
Simplest to configure requiring only general NetBackup knowledge
Typical configuration that is used for NetBackup customers
Assumes no fear of passive data interception on the wire as the backup runs

The following table describes the NetBackup parts that are used for a single datacenter with standard NetBackup.
Table: NetBackup parts for a single datacenter with standard NetBackup
Part | Description |
|---|---|
Master server | Communicates with the media server, standard NetBackup client 4 and Web server NetBackup client 5 in the DMZ. |
Media server | Communicates with the master server, standard NetBackup client 4 and Web server NetBackup client 5 in the DMZ. The media server manages the writing of unencrypted data to tape for clients 4 and 5. |
Tape | Contains unencrypted backup data that is written for clients 4 and 5. |
Clients | Specifies that client 4 is a standard NetBackup type and client 5 is a Web server type. The master server manages both clients and have their unencrypted data backed up to tape by the media server. Client 4 exists in the datacenter. Client 5 exists in the DMZ. Client 5 communicates to NetBackup using NetBackup only ports through the internal firewall. Client 5 receives connections from the Internet using HTTP only ports through the external firewall. Note that all NetBackup traffic for the lookup is sent unencrypted over the wire. |
Internal firewall | Enables NetBackup to access Web server NetBackup client 5 in the DMZ. Only selected NetBackup ports and possibly other application ports are enabled for data communication into and out of the DMZ. HTTP ports that are open in the external firewall cannot pass through the internal firewall from the Internet. |
Demilitarized Zone (DMZ) | Provides a "safe" area of operation for NetBackup client 5, Web server , that exists between the internal firewall and external firewall. Client 5 in the DMZ can communicate to NetBackup through the internal firewall using designated NetBackup ports. The Web server client 5 can communicate through the external firewall to the Internet using HTTP ports. |
External firewall | Allows external users to access the Web server client 5 located in the DMZ from the Internet over HTTP ports. NetBackup ports are open for client 5 to communicate through the internal firewall. Caution: NetBackup ports are not allowed to pass through the external firewall to the Internet. Only the HTTP ports to client 5 are open in the external firewall to the Internet. |
Internet | Specifies a collection of interconnected computer networks that are linked by copper wires, fiber-optic cables and wireless connections. The Web server client 5 can receive connections over the Internet using HTTP ports through the external firewall. |
