Question 1

The EMC Avamar backup administrator is starting an ad-hoc backup using the Avamar Administrator interface. However, you notice that avtar is not starting on the client. Where is the first place you should look to begin troubleshooting?

Accepted Answer

The avagent.log is the first place to check because it logs the activities of the Avamar agent, which is responsible for initiating the avtar process on the client.

Question 2

You are performing an ad-hoc backup from a Windows client. Which log file would you use to investigate communication issues between the Avamar client and the Avamar server utility node?

Accepted Answer

The avagent.log file is used to investigate communication issues between the Avamar client and the Avamar server utility node, as it logs the activities of the Avamar agent responsible for communication.

Question 3

What does an HFS check do?

Accepted Answer

An HFS (Hash File System) check is used to validate the integrity of a checkpoint in an Avamar server, ensuring that the data is consistent and not corrupted.

Question 4

A customer is currently running a 1 x 2 Avamar server with 1 TB nodes. In order to add new clients to their Avamar environment, the customer needs more capacity. How can this be achieved?

Accepted Answer

To increase capacity, migrating the backup data to a new 1 x 4 server using root-to-root replication is a viable option. Adding nodes to an existing Avamar server with RAIN enabled requires specific configurations and cannot be done by simply adding a single node. Upgrading the license does not increase physical capacity.
