Backup Network for DPM

As a backup administrator it’s important to backup and restore your servers and data on it.  You have you network set out (you probably use the production network for your backups, in non operating hours) your routines for backups, everything is set to go. All is going well until a backup did not run with the rest and now you have to run it during “Business Hours”.

DPM Production network

That where it gets tricky, running backups after hours is easy during business hours, not likely to be approved by Management. What do you do?

Configure a “Backup Network”, this way you can run your backups anytime you want without affecting production.

DPM Backup Network

  1. Network Addresses ( my production network runs on 10.0.0.0/24 and my backup network runs on 192.168.0.0/24).
  2. Configure the a secondary NIC on all DPM and Protected server with the address for your backup vlan (Example: IP: 192.168.0.1, Mask: 255.255.255.0,  NO gateway or DNS).
  3. On your DPM Server Hosts file configure Backup IP addresses (Example  192.168.0.1 dpmserver.test.local, 192.168.0.1 dpmserver, 192.168.0.2 protectedserver1.test.local, 192.168.0.2 protectedserver) you need both FQDN and NetBIOS.

  4. On the protected Servers Host file add the DPM Server address matching the backup network using both FQDN and NetBIOS. (Example:  192.168.0.1 dpmserver.test.local , 192.168.0.1 dpmserver)
  5. On the DPM Server open DPM Management Shell and run the following command: Get-DPMBackupNetworkAddress (for remote servers “Get-DPMBackupNetworkAddress – DPMServerName %servername%”, where you substitute %servername% for the actual name of your server) and it should return nothing because we don’t have a backup network configure yet.

    get-dpmbackupnetworkaddress

    Get-DPMBackupNetworkAddress

  6. Next we will configure the DPM Backup Network Address, by running the command: Add-DPMBackupNetworkAddress -DPMServerName %servername% -Address 192.168.0.0/24 -SequenceNumber 1 (On this command were already familiar with basically most of the command we add the -Address and the network, the -SequenceNumber will allow us to have multiple Backup Networks and it sets priority, on this example we only have one)

    Add-DPMBackupNetworkAddress

    Add-DPMBackupNetworkAddress

  7. After this has been set, we can run the Get-DPMBackupNetworkAddress and we will see the new network.
  8. On the DPM Server execute command: restart-service DPM

    restart-service-DPM

    Restart-Service DPM

  9. After this we go to the console and run a consistency check or Recovery Point on any protected server and after a while you will begin to see data being sent from protected server to DPM Server.

*Very important, you must be able to ping your DPM Server from the protected server and only the Backup Network IP respond, same from the DPM Server to a protected server only the backup network address must respond using both FQDN and NetBIOS (Example: ping dpmserver, dpmserver.test.local 192.168.0.1 …..).

I hope this information helps you out! and Merry Christmas and a Happy New Year.
