Scenario 6
A customer recently implemented an EMC Avamar solution in their primary data center. The environment consists of several Microsoft applications, including Microsoft SharePoint, Exchange, and SQL. An EMC Data Domain system was also deployed behind Avamar as the backup destination for these applications.
There are also several file system clients that have been configured to back up directly to the Avamar server.
One Avamar server and two Data Domain systems have been deployed to support this configuration. The Avamar server is operating close to full capacity and there is no room for expansion since it is already fully provisioned with the maximum number of nodes. The Data Domain systems have plenty of capacity left; each system is currently at 35% of utilization.
Refer to Scenario 6.
The customer noticed that while backing up the Microsoft Exchange clients, a significant amount of data is being stored on the Avamar server. The Exchange clients are configured to send their data to the Data Domain system.
What is an explanation for this behavior?
