Windows 2008 R2 Backup failing since VSF 5.1 SP2 is installed

We have a Windows 2008 R2 failover cluster.We installed Storage Foundation 5.1 SP2 to provide dynamic disks to the cluster.

We are trying to run a BMR backup on the active node but we have the folowing error:

The shared restore point operation failed with error (0x81000101) The creation of a shadow copy has timed out. Try this operation again.

We adjusted the timeout parameters to 20 minutes than to 30 minutes:

"HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\SPP"

- Create a new Registry value of type DWORD with name "CreateTimeout"

- Change value to 12000000(2*10*60*1000 = 20 mins) in decimal

Interestingly the backup is failing again and again:

The backup operation stopped before completing.
Detailed error: ERROR - The shared restore point operation failed with error (0x
81000101)
The creation of a shadow copy has timed out. Try this operation again.


Windows Backup timed-out before the shared protection point was created.
ERROR - The shared restore point operation failed with error (0x81000101)
The creation of a shadow copy has timed out. Try this operation again.

Is there any reason why the windows backup cannot access the SF disks to make VSS snapshots?

Before installing SF everything was working like a charm.

Hi

From the symptoms it looks like the Windows filesystem backup is failing and not the BMR backup.

Can you please confirm if that's case ?

That is definetly not true.If

That is definetly not true.If I include any disks that are created with SF the backup times out so soemthing is not working with SF disks because the windows backup VSS is not capable to create shadow copies of any disk that is created with SF.

Please ensure that Microsoft VSS provider is used for backup snapshots. Although you are not seeing the same errors, it is possible that FlashSnap is chosen for snapshots instead of VSS. See http://www.symantec.com/docs/TECH46631 for instructions to check/verify snapshot provider.

Please also verify compatibilty - BMR of W2008 is supported as from 7.0.1.

SFW 5.1, SFW 5.1 SP1 and SP2 is supported with BMR as from 7.1.

See the 7.x OS/platform compatibility list in the MASTER Compatibility list: http://www.symantec.com/docs/TECH59978 

We are talking about Windows

We are talking about Windows Server 2008 R2 native backup s BMR Bare Metal Recovery backup option which should be supported in VSF 5.1 SP2.

Hi there, Yes. We have

Hi there,

Yes. We have introduced support for SFW 5.1 in 7.1 release. BMR doesn't backup the disk it is the just the layout and system information which is captured. When you start the backup with BMR enabled attribute, one should see two backup jobs. The first one is the BMR Backup which just lasts for seconds. The next job is the actual data backup which in turn backs up the contents of SFW disks using VSS.

We are using windows backup

We are using windows backup to backup the failover cluster.I unregistered the Symantec VSS provider but I still get timeout problems.

The backup operation that started at '‎2011‎-‎08‎-‎24T14:47:02.075000000Z' has failed because the Volume Shadow Copy Service operation to create a shadow copy of the volumes being backed up failed with following error code '2155348001'. Please review the event details for a solution, and then rerun the backup operation once the issue is resolved.

And since we are clustering the dhcp role the BMR also wants to create a shadowcopy about a SF disk which is hosting the DHCP DB but whenever

is touching it it times out so it is pretty obvious that for some reason cannot access that disk to create a shadow copy of it.

I was not aware that Windows

I was not aware that Windows Backup had a BMR feature...

Maybe consider getting Enterprise backup software for your Enterprise software and data....
