BMR can protect more

BMR of Bare Metal Recovery is a ”new” feature in DPM 2010. This will give the administrator the possibility to recover the server from a dreadful state like corruption in the registry or total HW failure.

One important note is that the BMR function ONLY supports 2008 OS that has the WSB component installed. The WSB is the local backup feature on the server if it’s not installed BMR won’t work, pretty simple.

Regarding to Microsoft BMR will only protect the System State and C drive on the server you are protecting. You CAN modify the BMR function so it will protect all disks on the server! BMR functions with a CMDLET named Bmrbackup.cmd. To alter this configuration do this:

On the protected server, open the C:\Program Files\Microsoft Data Protection Manager\DPM\bin\Bmrbackup.cmd file in notepad. Modify this line and add an -include: statement to add the drive letter of the additional volumes to be included in the BMR backup.

rem Start a wbadmin.exe to create a BMR backup
start /WAIT %SystemRoot%\system32\wbadmin.exe start backup -allcritical -quiet -backuptarget:%1

rem Start a wbadmin.exe to create a BMR backup
start /WAIT %SystemRoot%\system32\wbadmin.exe start backup -allcritical -include:D: -quiet -backuptarget:%1
You will need to adjust the replica volume and recovery point volume sizes on the DPM server to account for the additional space required for the extra volume(s) being included in future BMR backups.
