Begin with a low value such as 20. Then monitor your next backup session to verify
that this has resolved any ESX server CPU usage issues.

This topic describes how to resolve issues that might arise with Avamar for VMware image
backup and restore.
If you encounter problems adding a vCenter server as an Avamar client, ensure that:
vCenter hostname, username, and password are correct.
◆
Port 443 is open between the Avamar server and vCenter system.
◆
If that does not resolve the problem, try turning off certificate authentication for all
vCenter-to-Avamar MCS communications as described on
authentication for all vCenter-to-Avamar MCS communications" on page
If a backup activity fails to start:
Ensure that an Avamar Image Backup Proxy has been properly deployed as described
◆
in "Deploy proxy clients" on page
The datastore for the source virtual machine has been selected on a running proxy
◆
server.
If that does not resolve the problem, the account used to connect to vCenter might not
have sufficient privileges. To verify account privileges, log in to the vSphere client with that
username and password. Ensure that you can access datastores on that client. If you
cannot, that account does not have the required privileges.
Virtual machine restores will fail if a snapshot for that virtual machine already exists.
When this occurs, the restore operation will return an error message similar to the
following:
