I tried to protect the SQL 2012 AlwaysOn availability group but failed with the error message:
DPM was unable to determine the right node for backing up the Availability Group database and hence failed the backup.
Database: MSSQL-DAG\Temp-Database (ID 32029)
I found similar error in another post but no one replied that thread. Is it a bug in SCDPM2012R2? I am so frustrated because last time I did lots of work to try to backup SharePoint 2013 with DPM2012 SP1/R2 but the final answer from Microsoft said that it's not supported if SQL Server 2012 AlwaysOn Availability Group was used.
Backup is important, and it's a MUST in day one of the product launch. I don't know why there isn't any solution from Microsoft.
