I have master server running Backup Exec 2012 SP3 and want to backup exchange 2013 servers MBX01 and MBX02 using DAG. I back it up with preferred server list and backup option "passive copy if not available active copy". But the backup error with cannot find a healthy copy in MBX02. Then i configured to backup just active only and same error happened. After read several technote i decided it is not about credential or name server resolve, so i decided to back it up just via mbx01 by only list mbx01 in preferred server and choose "passive copy if not available active copy". After backup completed with error i see in backup log the Backup Exec still trying to search passive copy in mbx02. For now i make a 2 policy, 1 for backup passive only in mbx01 and another for backup active only in mbx01 and it works. But if my exchange admin not statisfied i will create a case for this.
The point is, why Backup Exec cannot point just 1 server to backup either passive or active for DAG as I can do it in netbackup?
Best regards,
