Hi
I working on WinSrv2008 Core (with SP2) and from a few days I have a little problem with wbadmin and vss. When I try make backup I get couple times:

EventID 12292
"Volume Shadow Copy Service error: Error creating the Shadow Copy Provider COM class with CLSID {65ee1dba-8ff4-4a58-ac1c-3470ee2f376a} [0x80080005]

and

EventID 11
"Volume Shadow Copy Service information: The COM Server with CLSID {65ee1dba-8ff4-4a58-ac1c-3470ee2f376a} and name SW_PROV cannot be started. Most likely the CPU is under heavy load. [0x80080005]

and for end I always get this:

EventID 521
"Backup started at '2009-07-20T23:33:46.578000000Z' failed as Volume Shadow copy operation failed for backup volumes with following error code '2155348075'. Please rerun backup once issue is resolved."

I search on TechNet and other forums andI found some similar problems but any proposed solutions are not effective.
Any idea to resolve this problem ??


--
OK, I found source of problem
Service "MS Software Shadow Copy Provider" can't start.
Error 2: The system cannot find the file specified

When I try:
regsvr32 /i swprv.dll
I got message that dll was loaded but I got error 0x8000ffff

I found a manual solution to fix this. I checked in regedit this key:
[HKLM\SYSTEM\CurrentControlSet\Services\swprv]
and compare it with another WS08 instance.

I found then missing that key:
[HKLM\SYSTEM\CurrentControlSet\Services\swprv\Parameters]
I create "Expandable String Value":
Name: ServiceDll
Value: %Systemroot%\System32\swprv.dll

And service swprv works :)
Backup start normally.
Problem solved!

Hi Mgajda,
Thanks for sharing the solution.

No problem.
I hope that will help to others.

You are a Legend!, Had the some problem, found you post, fixed in 5 mins!

Thanks a Million mate.

Champion,

 

I have also same issues.  It's resolved now by following your instructions.

Ive added your fix to my Tech site. www.thetechgroup.com.au

 

Using Windows 7 Professional (upgrade from W7 Home) and have almost the same Event # and Error codes as in this post - windows will not set restore point and cannot use windows backup.  In System Protection, Protection Settings the Available Drives just indicates Searching, with no drives found.  Cannot uninstall programs using Windows Installer as it is inoperable. 

Have searched other forums and have been unable to find duplicate errors.  Tried to edit registry as noted but W7 apparently doesn't have HKLM\SYSTEM key.

Any suggestions or input, short of clean install of windows, would be appreciated.

I added the "Expandable String Value" - but I am still getting the same error when trying to run a backup.

"A Volume Shadow Copy Service operation failed. Unknown error. (0x800432f0)"

In my Event Viewer it says... "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 the following error code '2155348129'. Please review the event details for a solution, and then rerun the backup operation once the issues is resolved.

I'm also seeing an error in the application log Sourse=ESE, says Information store (2124) Shadow copy instance 15 aborted.

 Any help would be awesome, I'd really like to be able to backup the 'OS' drive of my server that runs my corporate office, thanks!!!!

Can you please provide us the output of executing vssadmin list writers command.

were you talking to me, how do I execute that command? thanks, Dave

Sorry for my previous post. In your problematic server, open a elevated command prompt and then execute the vssadmin list writers command. Then paste the output in this thread.

Thanks

ok, It lists Writer names, they all have no error except this one...

Write name: 'SPSearch4 VSS Writer'

writer Id: <35500004-0201-0000-0000-000000000000>

writer instance Id: <59df8981-cf79-4f32-894d-9806daab8a66>

State: [8] Failed

Last Error: Inconsistent shadow copy

I have exact same errors: VSS error 12292 and 11, but the solution didn't work for me.

For me the swprv parameters are correct, yet any attempt to access VSS hangs for at least 10 minutes then errors out, even "vssadmin list provider" hangs. According to my registry, there is only one provider registered, the "Microsoft Volume Shadow Copy provider".

This is very annoying as  any installation hangs for 10 minutes at "creating restore point", and I cannot do anything, I cannot disable VSS on C:, etc.

Please help!

Thank you !!!! iv been looking for this for ages !!!!

Hello,

Thanks a lot ! Worked for me as well ! :-).
