Volume Shadow Copy Service Errors- The 2 VSS error events in the Application Log where Event ID 22 followed immediately by Event ID 12292 – VSS was the source of both events.

At this point we asked the customer for more information about the Acronis provider and he told us that in the past he had evaluated an Acronis solution but had uninstalled it. This means that the Acronis uninstallation routine failed to remove all components, specifically the VSS provider. The evidence pointed to the Acronis VSS provider as the culprit behind the VSS errors. Since the customer was no longer interested in the Acronis product, the easiest method to troubleshoot the issue was to remove the Acronis VSS Provider.
