Backup is one thing , Restore is another especially disaster recovery , in this blog post we will cover the scenario where everything is gone except the backup tapes , first blog post will cover getting the domain up and running again where following posts will cover fileservers , sql and exchange.
Data Protection Manager requires a functional domain to be able to recover any data from tape , so first step will always be to get the domain up and running again.
In this post we a production domain test.local with dc10.test.local as the sole domain controller and dpm10.test.local as the Data Protection Manager server.
For restore purpose we setup dctemp10.temptest.local and dpmtemp10.temptest.local to restore the data , so a disaster recovery will always require staging of the restore data if the domain is lost.
Its always recommended to keep additional backup of the domain controllers outside of Data Protection Manager to ensure that we always no matter what happens can recover the domain and then start recovery
But always keep separate backup of domain controllers , there cant be to many backups if the media is located in a big safe somewhere
On the test.local domain we need a complete backup of the Domain Controller
And we will need the configuration database for Data Protection Manager
After creating the Protection Groups create a manual recovery point to tape , both for the domain controller and the Data Protection Manager configuration database
For testing I am using Cristalink brilliant Virtual Tape Library for Data Protection Manager http://www.cristalink.com/fs/ , so here the backup is located on 3 virtual tapes.
We need a new domain to restore to until we can get the original production environment up and running so here we created a new domain and is adding a Data Protection Manager Server to the same domain.
To simulate adding tapes from the library we use FileStreams Import feature Load From File
And then we can see the same tapes as we had before the wipe of the Domain Controller and Data Protection Manager Server
We then need to start a detailed inventory so we can see what’s on the tapes
After the detailed inventory have completed we need to Recatalog Imported Tape to add the content of the tapes to the Data Protection Managers configuration database
We then need to recover the System Protection from the tapes we did a recatalog on
Only restore option for systemprotection is a network folder
And its time to start the restore
Data Protection Manager == Success
We then need to share the folder out so we can access it from the Windows 2008 R2 installation media
to Restore from the recovered data we need to start the Windows 2008 R2 installer , DHCP needs to be enabled for networking support
Select a repair
As there are no local images to restore from select next
And start networking
Connect to the DPM Server
With Credentials from the new temporary domain
Select the Image to restore
Start the ReImage
For about 12 minutes on my test setup
And after a reboot and setting fixed ip address the domain is up and running , and we now have a working domain so we can start to restore the Data Protection Manager server and then start restore all remaining workloads.
