SCCM site back-up is one of the essential back op options. Even your environment is stable, you may receive alerts in smsbkup.log as below:
Cannot find the dependent writer. The dependant component cannot be backed up.AddDependentComponent(pDependency) failed. Error code = 0x80,004,005.Error description = .Error: GatherWriterMetadata failed.
This error indicates that either SMS_SITE_VSS_WRITER or SQL Server VSS Writer is not listed as one of VSS.
In order to eliminate this error,
- Start CMD with admin privilege.
- Enter the command VSSAdmin list writers
- Review the list for the missing writer.
- Restart the missing writer service from services.msc
- Start the SMS_SITE_BACKUP service.
- Monitor smsbkup.log for any issues. Ensure that the back-up is completed.
