Backup Via Diskshadow Windows Server 2008: Unable To Restore Hyper-V Vms

[jagz]

hi at all,

 

I have a problem with the VMs restore test.

 

I have created a backup script in host server for my Hyper-V VMs: in this script a VSS backup via diskshadow is created, then VSS is exposed and copied on another location (NAS):

 

DELETE SHADOWS ALL

# Startup settings

SET CONTEXT PERSISTENT

SET METADATA c:\BACKUP\Backup.cab

SET VERBOSE ON

# Starting Backup

BEGIN BACKUP

ADD VOLUME C:\ ALIAS SystemVolumeC

#

CREATE

# mount VSS backup

EXPOSE %SystemVolumeC% X:

# run cmd and copy vhd on NAS

EXEC C:\BACKUP\copy_VMS_on_NAS.cmd

UNEXPOSE X:

# end backup

END BACKUP

 

All 2 Vms are windows server 2008 R2, host too. one is the PDC and one is Exchange 2007 SP2 server.

 

For my recovery test I have copied all 2 backed-up VHD to another isolated server. I have recreated VMs using the VHD and reconfigured network like VMs in prod. But when I try to login on exchange server with AD Administrator I can't because this server can't contact the AD server. Both VMs are able to ping.

 

* adsiedit from exchange server can view all AD domain but i can't login (I'm able to login only with local account)

* nltest /SC_VERIFY:domain return an ERROR_ACCESS_DENIED because I'm local user and not domain admin

* DCdiag don't display any major error, only about: replication failure (the second DC is not part of

recovery test) and "RPC service unavailable" but in w2k8 it's not used (right?)

 

I think that "security channel" is broken but i don't know how to fix because I can't login to exchange server via network user.

 

Can you help me? right now, there is no good backup of my production VMs and I know that this method (DISKSHADOW backup with Hyper-V writer) is supported by microsoft.

 

Thank you!!
