Exchange Backup Failur

Hi,

We have exchange 2010  DAG , backup with hp Dataprotector.

While taking the backup its gives the below error in event log ,

“Volume Shadow Copy Service error: Unexpected error calling routine IMultiInterfaceEventControl::GetSubscriptions.  hr = 0x80010108, The object invoked has disconnected from its clients.”

“Volume Shadow Copy Service error: Error on creating/using the COM+ Writers publisher interface: BackupShutdown [0x80042302, A Volume Shadow Copy Service component encountered an unexpected error.”

I have checked the vss writer status & its showing rewritable error for both exchnage writer.

I have restart the Server but no luck.

Please suggest.

Hi All,

Issue has been resolved after Re-register the VSS components


Sometimes re-registering VSS core components can fix errors. Copy the following commands to Notepad and save the file with a ‘.bat’ extension. Run the .bat file by opening a command prompt and entering the .bat file name.
cd /d %windir%\system32
net stop vss
net stop swprv
regsvr32 /s ole32.dll
regsvr32 /s oleaut32.dll
regsvr32 /s vss_ps.dll
vssvc /register
regsvr32 /s /i swprv.dll
regsvr32 /s /i eventcls.dll
regsvr32 /s es.dll
regsvr32 /s stdprov.dll
regsvr32 /s vssui.dll
regsvr32 /s msxml.dll
regsvr32 /s msxml3.dll
regsvr32 /s msxml4.dll
vssvc /register
net start swprv
net start vss

Thanks

solution says that problem is due to vmware backup taken at the same time & it is disk backup, but in our case its a Tape lavel backup.

What is the Exchange version ?
So even after restarting the server the writers done come to Stable ?
Are you backing System State as well ?

Hi Rancy,

Exchange version is 2010 DAG Environment.

Yes after restart the Server Exchange Writers comes to stable mode, but once backup started it goes to rewritable mode.

No, We are not taking system state backup , shall I test it, please suggest.

Note: I have pointed out that Windows update is 1 years back :( & Exchange 2010SP2 Rollup1, I suggest latest rollup6.
