I have a SQL 2008 Express database that I backup monthly from a SQL Job on SQL 2005 Standard with SP4. I just upgraded the SQL Express Server to SQL Express 2012 and now my backup job is failing. On the SQL 2005 server, I configured the connection string using the Manage Connections interface. The backup database task makes the connections and sees all of the databases on the SQL Express instance.The SQL Express server allows remote connections and SQL Browser is running. Integration Services is running on the SQL Express computer as well.
My thought is that I need to install the Native SQL Client for SQL 2012 on the SQL 2005 Standard server. But, this is our busiest production server and I don't want any unintended consequences.
1. Is this the correct way to solve the issue?
2. Are there any negative consequences to installing the SQL 2012 client on my SQL 2005 server?
