VSS Shadow Copy Backup Error
Posted by Matthew Bennett on 13 December 2019 12:24 PM
Windows Server Backup error: 'Backup succeeded but some components backed up were inconsistent in the snapshot. The application this component belongs to might not function properly after this backup is used for recovery.'

Method One

Following a system reboot, ensure the following Windows Services are running correctly - restart if required.
- COM+Event system
- Microsoft software shadow copy provider
- Volume Shadow Copy

Note restarting "COM+Event system " service will restart System Event notification service and Background intelligent Transfer service due to the dependencies.
After restarting theseĀ  services VSS will return to stable state.

Method Two

A faster but more disruptive in the production environment.

Schedule a System Reboot at 7pm. This will clean the incorrect status of the VSSĀ  writers and backup will now succeed.
