Backup and Recovery - Oracle Exadata Recipes: A Problem-Solution Approach - page 191

storage, use backup media servers to communicate with agent software on the servers, and use backup mechanisms
to copy data over a supported transport medium to the storage pools.
On the Exadata Compute Nodes, you have the choice of using Ethernet or InfiniBand as your transport protocol,
so your backup media servers must be able to communicate with the compute nodes over Ethernet or InfiniBand
network protocols.
Once you've designed your backup strategy, install your third party or Oracle Secure Backup agent software
on your compute nodes, configure the software according to vendor documentation, and design and execute your
backups according to your organization's policies.

■ Backup network planning and design are outside the scope of this recipe as most organizations have unique
network topologies and enterprise backup policies or designs. additonally, third-party vendor backup agent installation
and configuration steps are outside the scope of this recipe.

Note

How It Works
Oracle allows for the installation of third-party backup software and agents on the Exadata Compute Servers, such
as IBM Tivoli, Symantec NetBackup, EMC Networker, Oracle Secure Backup, or any backup agent certified on your
compute node operating system.
Below are some items to consider when designing your third-party backup solution for your Exadata
Compute Nodes:

• An Exadata DMA can leverage existing corporate backup software and infrastructure to

backup software on the Exadata Compute Nodes.

• The compute nodes do not have fiber HBA cards, nor do they have physical capacity to install

them, so your backups will need to be done over either 1 GbE, 10 GbE (if you have ordered
10gbE cards for your machine), or InfiniBand.

NET3 Additional Network as the backup network; if this is
your choice, ensure that the NET3 configuration meets your backup network configuration
requirements in terms of network bandwidth and redundancy.

• Some organizations use Exadata's

• Customers are increasingly adopting backup strategies that use the high-speed,

high-bandwidth InfiniBand network to minimize backup times and optimize the overall
backup strategy. If this is the policy you adopt, ensure your backup media servers are
capable of communicating over the InfiniBand network.

• If you wish to back up multiple Exadata Database Machines using the same InfiniBand

network, you may have to take care to use distinct ranges of InfiniBand IP addresses when
configuring your switches so as to avoid IP address conflicts.

Problem
You wish to use available capacity in your compute node's local SAS disks and logical volume management features to
perform backups of your compute node software.
