|
|
I've started to get failures on a few long-established backups, apparently as a result of a failure to create the Volume Shadow Copy. The relevant part of the log is:-
2014-03-29 01:10:54 : Initializing Volume Shadow Copy DLL ...
2014-03-29 01:10:54 : Creating Volume Shadow Copy for S:\ ...
2014-03-29 01:10:54 : Gathering writer metadata...
2014-03-29 02:51:46 : Initializing writer metadata...
2014-03-29 02:51:46 : ERROR: COM call "m_pVssObject->GetWriterMetadataCount (&cWriters)" failed.
2014-03-29 02:51:46 : - Returned HRESULT = 0x80042301
2014-03-29 02:51:46 : - Error text: VSS_E_BAD_STATE
2014-03-29 02:51:46 : [Volume Shadow Copy creation failed for S:\. E_UNEXPECTED- You may need to stop and restart the Windows Volume Shadow Service] Error.
2014-03-29 02:51:47 : [Volume Shadow Copy creation failed for S:\.
After this failure, the program tries to copy the files without the Volume Shadow Copy and, of course, fails if the file(s) are in use.
I always run VV Pro in Administrator mode. The system is Windows 8.1 Pro. I've tried re-installing VV Pro, but that didn't help.
Volume Shadow Copy Service is running and re-starting it or re-booting doesn't help.
Hopefully you'll be able to suggest something from the log entries.
Thanks,
Mike |

Hi, if you list all the VSS writers using command in command line (cmd)
vssadmin list writers
does it show any writers with errors ?

Hello,
I did that - similar result, long delay then "Error: A Volume Shadow Copy Service component encountered an unexpected error."
I checked the Application Log and there are two messages:-
Operation: Instantiating VSS server
Volume Shadow Copy Service information: The COM Server with CLSID {e579ab5f-1cc4-44b4-bed9-de0991ff0623} and name IVssCoordinatorEx2 cannot be started. Most likely the CPU is under heavy load. [0x80080005, Server execution failed]
Volume Shadow Copy Service error: Unexpected error calling routine CoCreateInstance. hr = 0x80080005, Server execution failed.
Nothing else was going on with the CPU, by the way, as the message suggested.
I haven't really been able to find anything helpful on Google, so it's starting to look like a Windows re-install, isn't it?

Many thanks for the information. I checked all the services mentioned in the article and they seem to be OK. I wasn't able to check providers with diskshadow, because that's apparently only included in Server versions.
The strange thing is, I restored a disk image from a time when I know the Shadow Copy was working normally, and it still doesn't work.
Anyway, I'll keep trying. Thanks again for taking the trouble to investigate. I appreciate it very much.

Hello,
Just in case it helps someone else, after a lot of unsuccessful recovery of saved images and re-installation, I finally found the answer through a Google link regarding an error message connected with the failure of System Restore, which also uses the Volume Shadow Copy Service.
Someone reported that it was caused on their machine by a utility called X-fast USB, which is supplied by AS Rock with their motherboards, and maybe others.
I uninstalled that, and the problem was solved.
Many thanks again for your help.
