DPM over a Backup Network
Anyone trying to move their network traffic over a seperate interface to lighten the load on your primary LAN?
Data Protection Manager 2007 (DPM) allows you to configure a backup network address to ensure that DPM backups do not slow down your primary network. The backup network address is created when you put separate network interface cards (NICs) on the DPM server and the protected servers and connect them through a separate LAN. As a result, backup data traffic does not impact the primary network.
You can set up your backup network address using DPM 2007 Management Shell (PowerShell) cmdlets.
The commad to run inside the PowerShell is as follows: (replace TESTDPMSERVER with your DPM server name)
Add-BackupNetworkAddress -DpmServername TESTDPMSERVER -Address 192.168.1.0/24 -SequenceNumber 1
|Note The subnet should cover the entire range of network addresses for the DPM server and the servers you intend to protect.|
The key to making this work is the DNS resolution the backup network. If you ping your protected sever it should reply with the ip address of your backup network.
Sounds easy right?
Well I had my DNS buddy create a sub-domain for the backup network. He added a few static entries for the servers I am trying to protect. When I ping them now it replies with the backup network IP address and the backup domain.
So you would think that my backup jobs are now coming over my backup networ right?
