How to Access a iSCSI (WBADMIN) Backup in Server 2008 R2 Bare Metal Restore

I am working on a new strategy for backup of Server 2008 R2 data.   The SAN is a Synology DS213J configured as iSCSI.  The servers to be backed up are Intel S2600CPand S1200BT motherboards.

I have the backup running smoothly.  Now I want to validate that I can do a WBADMIN bare metal restore from the iSCSI backup.  Booting to the DVD and taking the repair path, I get stuck when I reach the advanced button on "re-image your computer."  I have been able to install a NIC driver (although I am not sure it is the right one).  After that, I can "see" the Synology device by accessing it via the UNC name (DISKSTATION).  It prompts for a username and password.  I provide that, but the explorer window that opens shows no entries.  I think that is expected since there are no shares on the Synology.

How can I access the iSCSI backup when performing a WBADMIN bare metal restore?

Thanks in advance,
Leon

Using windows built-in backup? You can't. Windows PE is what runs from boot media and that has no iSCSI support, which is what you'd need. Most companies with a budget for a SAN either use a mower full featured backup product or use off-site media for bare metal and the iSCSI target only for data incrementals. It is simply a known limitation of WSB and WinPE.

For anyone that may be interested in a workaround, I have been able to perform a bare metal restore of a backup that is stored on an iSCSI NAS.  At a high level, I used a Windows 7 computer to act as an intermediary.  The windows 7 machine picks up the iSCSI disk and shares it out.  When performing the bare metal restore, I added the network drivers and picked up the backup from the share.  It may not be "simply elegant", but it does allow WBADMIN to create incrementals.

WHICH Network Drivers? I've tried your steps (as well as others) but to no avail.

How does Windows 7 understand that this is a system image, and why does WS2012R2 NOT understand that?

I've made a copy of the data from the iscsi drive to a physical drive on the Win7 machine, and then shared that directory.

WS2012R2 still does not see the system image?

You need to find the network drivers specific to your hardware.  This can be a bit of a challenge for intel.  They bury the drivers in the exe.  For example, my server is S1200BT.  It has two intel NICs.
NICs: 82574L and 82579.
I unpacked the exe on another machine and used the grep command in Cygwin to search the contents of the folders for each driver by name.  The drivers were located in the following files:
NDIS62/e1q62x64  
NDIS62/e1c62x64  
Copy these folders to a flash or usb to mount on the server at restore boot.
Once in the right folder, use the setup information file with the right name and select the setup information file.

Good luck,
Leon

BTW - No need to make a copy on the windows 7 machine.  When the iSCSI is shared out, WS2012R2 will see the folder  WindowsImageBackup in the root of the shared drive if it has network access (you will need to enter connection info - user, password, and group id).
