Single datacenter with Media Server Encryption Option (MSEO)
This single datacenter with the Media Server Encryption Option (MSEO) example typically includes more than 50 hosts. All externally facing hosts make use of the Media Server Encryption Option (MSEO). In this example, clients use the MSEO option for all hosts.
The single datacenter with Media Server Encryption Option (MSEO) includes the following highlights:
The MSEO is a newer option in NetBackup
Protects data that is sent off-site
Data is still sent from the client in the clear, implying that passive data interception off the wire is an acceptable risk
Key management and encryption are managed in a central location equating to a single point of failure. Using the high availability cluster can help.
Media server must be robust to handle multiple clients at once
Useful where you need to send encrypted tapes off-site but want to off load encryption from the client, which is CPU intensive
Must have keys to get data back. Lost keys mean lost data. (See information on key share backup in the Encryption Chapter).
Figure: Single datacenter with MSEO shows an example single datacenter with MSEO.
The following table describes the NetBackup parts that are used for a single datacenter with MSEO.
Table: NetBackup parts used for a single datacenter with MSEO
Communicates with the media server, MSEO clients 1, 2 and 3 and the MSEO Web server client 5 in the DMZ.
Communicates with the master server, MSEO clients 1, 2 and 3 and the MSEO Web server client 5 in the DMZ. The media server communicates with the MSEO device that enables the writing of encrypted data to tape for clients 1, 2, 3, and 5.
Specifies that the MSEO hardware appliance off-loads encryption from individual clients and generates encrypted data for clients 1, 2, 3, and 5. That encrypted data is then written to tape. The individual client CPU performance is improved (relative to client side encryption) by using the MSEO appliance.
Contains MSEO encrypted backup data that is written for clients 1, 2, 3, and 5. The encrypted tape is transported off-site to a vault for disaster recovery protection.
To decrypt the data, the key(s) used to encrypt the data must be made available.
Specifies that the transport truck moves encrypted tapes off-site to a secure vault facility. If a tape is lost during transport, the datacenter manager has potentially reduced the risk of a data breach. Data breach has been reduced through the use of data encryption.
Provides a safe storage facility at a different location than the datacenter that promotes disaster recovery protection.
Specifies that clients 1, 2, and 3 are the MSEO type and client 5 is a Web server type (also using the MSEO option). Both types can be managed by the master server and have their encrypted data backed up to tape. Backup is done through the media server attached MSEO hardware appliance. Clients 1,2, and 3 exist 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.
Specifies that it is used by NetBackup to access client 5, Web server, 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 open in the external firewall cannot pass through the internal firewall.
Demilitarized Zone (DMZ)
Provides a "safe" area of operation for the Web server client 5 that exists between the internal firewall and external firewall. The Web server client 5 in the DMZ can communicate to NetBackup through the internal firewall using designated NetBackup ports. The Web server client 5 can also communicate through the external firewall to the Internet using only HTTP ports.
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 Web server client 5 to communicate through the internal firewall to NetBackup. The NetBackup ports are not allowed to pass through the external firewall to the Internet. Only the HTTP ports of Web server client 5 can pass through the external firewall to the 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 communicate over the Internet using HTTP ports through the external firewall.
