What should be considered for the next backup schedule?

A newly hired backup administrator has taken control of a Dell EMC Avamar server that is protecting an Exchange DAG environment with 3 nodes. Backups of the DAG are running successfully. The

administrator wants to perform an on-demand backup of the entire Exchange DAG, but cannot find a client that represents the DAG.

What is a possible reason for this?

To what value should the hashcachemax value be set?

A current EMC NetWorker customer is backing up a mix of Microsoft Windows and Linux servers in their environment. They have decided to integrate two Avamar servers into their environment as deduplication nodes.

Clients will be configured to back up to the first node with Avamar replication configured between the two.
