Event Type:Error
Event Source:VSS
Event Category:None
Event ID:12298
Description:
Volume Shadow Copy Service error: The I/O writes cannot be held during the shadow copy creation period on volume.
The backups generally fail with this error if the Microsoft Volume Shadow Copy Service (VSS) writers on the system are not stable. As the VSS writers are not stable they will not be able to quiesce (pause) the volumes that are being backed up and the snapshot process fails.
1. Open a command prompt and run the following command: vssadmin list writers
All the writers listed should be in Stable state with no errors. If the writers are not stable restart the server and then check them again.
2. Install any updates for VSS (depending on the version of Windows)
If the above steps do not resolve the VSS issue please contact Microsoft technical support for further assistance on troubleshooting VSS.
