VSS software provider error when you use DPM on a Windows 8 or Windows Server 2012-based computer


Assume that on a Windows 8 or Windows Server 2012-based computer, a disk is removed from the computer unexpectedly. In this situation, when you try to back up this computer by using Data Protection Manager (DPM), the backup operation fails together with a Volume Shadow Copy Service (VSS) software provider error message that resembles the following, which indicates that access was denied:
ComputerName : <computername>
SourceName : VSS
EventCode         : 12289
TimeGenerated     : <DateTime>
Message           : Volume Shadow Copy Service error: Unexpected error DeviceIoControl(\\?\Volume{97823f6b-e259-11e2-93fe-6cf049017635} - 00000000000003FC,0x0053c06c,000000BCC1213070,0,000000BCC1214080,4096,[0]).  hr = 0x80070005, Access is denied.

Additionally, VSS tracing information is generated that resembles the following:
6216 [13:57:37.769 P:04AC T:1460 INCICHLH(0521)    SWPRV] THROW[CVssDiffArea::SetExplicit] Unexpected error calling a provider routine: DeviceIoControl(\\?\Volume{3c8064f7-be4e-11e2-93fe-00155d25661e} - 00000000000003C4,0x0053c06c,0000006732E109E0,0,0000006732E119F0,4096,[0])  [hr = 0x80070005]

After you install this hotfix, snapshot protection is used to protect DPM snapshots to prevent this issue.
