I have exchange server and backup server as physical boxes sitting outside the virtual environment. I have another two physical hosts which are hosting 5 vms on them.
I am using symantec be 11d version. Before I start virtualization, backup is running smootly. exchange server with 77GB data took about 1.5 hours to back up to disk. Now it will take a full day to backup the speed is ony 46mb/min.
No matter before or after virtualization, exchange server and backup server are not touched. why this would happen? I am puzzled.
I apprecite any suggestion.
