Backup of a Sharepoint 2013 Farm fails with 'V-70-57344-794 - Error: Unable to query the Team database meta-data' on the 'Workflow Service Application Proxy' component.


Error Message

In SPSWrapper log;

Name :: Workflow Service Application Proxy
INF :: Unable to cast object of type 'Microsoft.SharePoint.WorkflowServices.WorkflowServiceApplicationProxy' to type 'Microsoft.SharePoint.Administration.SPServiceApplication'.
INF :: Unable to cast object of type 'Microsoft.SharePoint.WorkflowServices.WorkflowServiceApplicationProxy' to type 'Microsoft.SharePoint.Administration.SPServiceApplication'.
Executing Powershell cmd Get-SPServiceApplicationProxy -identity 92187b07-c267-43d8-a088-69c075810bf3
Error  exception in running cmd Get-SPServiceApplicationProxy -identity 92187b07-c267-43d8-a088-69c075810bf3 Exception is Exception getting "IsClientValid": "Could not load file or assembly 'Microsoft.Workflow.Client, Version=, Culture=neutral, 
PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified."
Error in BackupSSP


The error is due to failing to interpret the response from the 'IsClientValid' query, when Sharepoint Workflow Manager is configured.




Deselect the 'Workflow Service Application Proxy' component from the Farm backup. The backup job will then complete successfully. Although this component is a part of the Farm configuration, it is not a critical component and deselecting that will have no effect on the backup\restore capabilities of the Content DBs that hold the user data.
