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.
Windows Server Backup is timing out during shadow copy creation since it is taking more than 10 minutes.
- Run regedit.exe and navigate to "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
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 20*60*1000, 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?
Great, thank you very much.
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.
Have just had this error on an SBS 2011 (essentially for all intents and purposes 2008 R2).
Will give this a go.
In response to David W:
The problem with Microsoft linking error messages to hyperlinks is that they keep changing the URLs on the KBs so you would just end up with a link that did you no good.
Yes you could say well stop bloody changing the URLs but ha-ha yea good luck with that.
Does this work in Windows 2012 too ?
I'm getting backup errors on my new 2012 cluster.
Is it working for Windows 2012, having issue with Windows 2012 Hyper V Failover cluster CSV backups using MS DPM 2012SP1
This fixed the problem I was having with MS Data Protection Manager.
Running SBS 2011, First had error 0x800423F0 and ran Share Point setup wizard. then had error 0x81000101 and made the new registry entry as above and my server back up is now working. thanks to all concerned
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?
