Multi-datacenter with standard NetBackup
A multi-datacenter with standard NetBackup is defined as a medium to large group of hosts (greater than 50). These hosts can span two or more geographic regions and can be connected by a Wide Area Network (WAN). In this example one datacenter is located in London and the other datacenter is located in Tokyo. Both datacenters are connected through a dedicated WAN connection.
A multi-datacenter 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 multi-datacenter with standard NetBackup includes the following highlights:
NetBackup spans two or more geographic regions through a WAN
Centralized naming services typically exist
Greater than 50 hosts in size
Simplest to configure; requires only general NetBackup knowledge
Assumes no fear of passive data interception on the wire as the backup runs
The following table describes the NetBackup parts that are used with a multi-datacenter that has implemented standard NetBackup.
Table: NetBackup parts for a multi-datacenter with standard NetBackup implemented
Part | Description |
|---|---|
London datacenter |
Contains the primary server, media server 1, client 4 standard NetBackup, and the unencrypted data tape for client 4. The London datacenter connects to the Tokyo datacenter through a dedicated WAN connection. |
Tokyo datacenter |
Contains the media server 2, client 10 standard NetBackup, and the unencrypted data tape for client 10. The Tokyo datacenter connects to the London datacenter through a dedicated WAN connection. |
Wide Area Network (WAN) |
Specifies the dedicated WAN link that connects the London datacenter to the Tokyo datacenter. The WAN provides connectivity between the primary server and media server 2 and client 10. |
Primary server |
Specifies that it is located in London and communicates with media server 1 in London. The primary server also communicates over the WAN with the media server 2 in Tokyo. The primary server communicates with standard NetBackup client 4 in London and client 10 over the WAN in Tokyo. |
Media servers |
Specifies that the multi-datacenter can have two media servers. One media server is in London and the other is in Tokyo. The media server 1 in London communicates with the primary server and standard NetBackup client 4 also in London. Media server 1 manages the writing of unencrypted data to tape for client 4 in London. The media server 2 in Tokyo communicates with the primary server in London and standard NetBackup client 10 in Tokyo. Media server 2 manages the writing of unencrypted data to tape for client 10 in Tokyo. |
Tapes |
Specifies that tapes are produced in both the London and Tokyo datacenters. The London tape contains unencrypted backup data that is written for client 4. The Tokyo tape contains unencrypted backup data that is written for client 10. |
Clients |
Specifies that the clients are located in both the London and Tokyo datacenters. Clients 4 and 10 are standard NetBackup types. Both clients can be managed by the primary server that is located in London. Their unencrypted data is backed up to tape by the media server. Unencrypted data is written to both client 4 tape in London and client 10 tape in Tokyo. Note that all NetBackup traffic for client 10 lookup is sent unencrypted over the wire (WAN) from Tokyo to London. |
Internal firewalls |
Specifies that internal firewalls are not used at the London or Tokyo datacenter with standard NetBackup. |
Demilitarized Zones (DMZs) |
Specifies that DMZs are not used at the London or Tokyo datacenter with standard NetBackup. |
External firewalls |
Specifies that external firewalls are not used at the London or Tokyo datacenter with standard NetBackup. |
Internet |
Specifies that the Internet is not used at the London or Tokyo datacenter with standard NetBackup. |
