Windows Server Backup failed to backup with error 0x81000101

  • Article

Symptom:

Sometimes Windows Server Backup failed to backup the data. The error is:

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

In the event viewer, found the following error:

The backup operation that started at '‎**** 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.

Cause:

Windows Server Backup is timing out during shadow copy creation since it is taking more than 10 minutes.

Resolution:

- Run regedit.exe and navigate to "HKEY_LOCAL_MACHINESoftwareMicrosoftWindows NTCurrentVersionSPP"

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

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

    Does this work in Windows 2012 too ? I'm getting backup errors on my new 2012 cluster.

    There's an error in the solution. 12000000 is 200 minutes! You only need 5 x zeros, not 6. i.e. 1200000

    I wouldn't advise using 200 minutes as the timeout because if your server needed that long to take a snapshot then there is a far more serious problem that needs fixing. I'm even concerned in waiting 20 mins but at least that fixes the problem for most people, even though something unhealthy is happening to cause it to take that long.

    I have the same problem. Microsoft seems to have some big problems right now with this and cannot seem to fix it.

    Unless I'm missing something, there's a problem with the math. 20 minutes, expressed in milliseconds is 20601000, but that's 1.2 million not 12 million as posted. Since there's not much (as in anything I can find) documented on this key the obvious question is: is there an error in the suggested value, should be 1200000, or in the formula/units explained?

    I've been doing Windows backups since NT4 and I have found it unbelievable how f'd up backups can be in Windows 2008. "What were they thinking".

    Microsoft has no clue how to write an error message with any real meaning. There are billions of available numbers... how about linking the error message to meaningful resolution pages.

    I made this change, and it helped for a while, then the error came back. I changed it to 40 minutes. As far as the question above concerning the math - my log shows the (failed) backup ran for 2 hours. I assume their math is wrong, but what would cause a shadow copy to take so long?

    I assume this is due to time waiting for a quiet point? (Hence the erratic results)

    Thank you shari77.
    Uninstaling ASRock Xfast USB and rebooting solved the 0x81000101 problem.
