Data Protection Manager 2012 beta 2 (Disaster Recovery of Data Protection Manager Server)

repost from

This post will cover the disaster recovery of Data Protection Manager Server , there are a few ground rules that needs to be followed.

NEVER ever loose your tapes (duh)

ALWAYS keep a backup of the configuration database

ALWAYS keep a domain controller alive , and keep a backup of a domain controller with Windows Backup so it can be restored if everything else is gone.


If we loose our data protection manager server due to hardware issues flood earthquake or fonzie attack we need always to keep our data on tape a copy on a different Data Protection Manager with the DPM to DPM backup feature.

In this scenario we will kill the Data Protection Manager server and recover data from tape only, i use the excellent filesteamer from awesome for testing and for long term recovery to disk.


DPM uninstalled and all data deleted, remember if you need to rebuild the operating system you need to call the server the same as before the rebuild.


We then need to start the installation of Data Protection Manager


This setup used the local sql database so for testing we will create a new sql instance for the Data Protection Manager Server


And we will use the default file paths for install


After install we don’t have any recovery points as all our data is located on tape and we have lost our configuration database


Go to Management and Libraries


Select Rescan for Data Protection Manager to scan for tape devices


Yes please.


When the tape library is connected after rescan we can see the tapes but not what’s on them


We then need to perform a detailed inventory


After the detailed inventory the tapes now shows as imported with label the tapes was created with


If you know what tape the data protection manager configuration database is on in the newest version run the “Recatalog imported media”


Yes please , this will take time


But very fast on a test setup with a virtual tape library


We can then see the Data Protection Manger server and recovery points for the configuration database


Data Protection Manager cant restores its own database directly so it needs to be restored to a network location


And we can only restore locally as we have no agents connected to the Data Protection Manager server (but we need to db. locally)


Here we will just restore the Data Protection Manager configuration database


And Data Protection Managers trade mark “Successful” as usual clip_image021


There are different ways to connect the database i prefer just to stop all Data Protection Manager services


Detach the database from our clean install


Copy the database files from the restore to C:restore (example)


Attach the database files


And reboot the data protection manager server


After reboot we can now see that Data Protection Manager knows the tapes


And the agents is connected again and we can restore from multiple sources.

There is some housekeeping that needs to be run after this but this will get you up and running and start restoring data
