I have a Problem with my Commvault 11 SP6 installation.
Wen i create a Virtual-Server Backup and enable Application aware backup i have to create a Sap-Copy storage policy to get thinks working. when i dont have this policy i always get the following error:
"Error Code: [19:857]
Description: MediaAgent not installed on VSA proxy 10004_psrv04 or Snap copy not created on storage policy associated with VSA subclient. Install mediagent on proxy 10004_psrv04 AND/OR create the snap copy for storage policy associated with VSA subclient and re-run the VSA job for a successful App Aware backup of VM psrv01_01.

In this description you can read the you have to install the mediaagent on the vsa proxy OR yuo have to enable sanpcyop. i have installed the mediaagent on the vsa proxy (10004_psrv04, win2012r2). so whats the problem here.
