I have 3 node SQL 2012 AlwaysOn Availability nodes with the 3rd node as Read-Only.
The backup job within SQL Maintenance plan is failing with the following error:
Failed:(-1073548784) Executing the query "declare @backupSetId as int
select @backupSetId =..." failed with the following error: "Cannot open backup device 'C:\\SQLDBName_backup_2014_06_08_170156_9292095.bak'. Operating system error 2(The system cannot find the file specified.).
VERIFY DATABASE is terminating abnormally.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
I have verified the SQL AlwaysOn Backup preference to be "Prefer Secondary"
Is there any special steps/settings I need to do to setup and run the backups using maintenance plan in SQL AlwaysOn?
