Error: VSS error 0x80042316

Description

This warning is given typically when the Volume Shadow Copy Service (VSS) is unable to run due to another instance of VSS already running.

Resolution

1. More than one backup program installed

If you have more than one backup program installed on your machine, disable all of the programs except for one and run the backup job again.

2. Scheduling Conflict

Having two backup jobs running at the same time within BackupAssist, both trying to run VSS can cause this error to occur.

Please change the time that one of the backup jobs is scheduled to start so that a conflict isn't likely to occur.

3. Previous VSS snapshot hasn't completed properly and is still running

Stop and Restart the Volume Shadow Copy service. You can do this by going to Control Panel > Administrative>Tools > Services.

Once in Services, find Volume Shadow Copy and right click and select 'Restart'.

Also, a reboot of the server has been known to clear this issue up as well.

4. Re-register .dll files associated with VSS service

Open command prompt and change directory to windows/system32 and type in the following commands:

regsvr32.exe /i eventcls.dll

regsvr32.exe /i swprv.dll

regsvr32.exe vssui.dll

regsvr32.exe vss_ps.dll

regsvr32.exe msxml.dll

regsvr32.exe msxml2.dll

regsvr32.exe msxml3.dll

regsvr32.exe ole32.dll

regsvr32.exe oleaut32.dll

regsvr32.exe es.dll

regsvr32 stdprov.dll

Vssvc /Register
