Explanation:
Explanation/Reference:
Server maintenance activity monitoring
Avamar performs the system maintenance operations for backup data on the Data Domain system, including HFS checks, checkpoints, rollbacks, garbage collection, and secure backup deletion.
The ddmaint utility implements all required operations on the Data Domain system for the Avamar server.
The ddrmaint utility is installed on the utility node of a multi-node server, or the single node of a single-node server, during Avamar server installation. The ddrmaint utility is not installed on the data nodes of the Avamar server.
The ddrmaint utility logs all maintenance activities on the Avamar server in the ddrmaint.log file. The following directory on either the utility node of a multi-node server or the single node of a single-node server contains the log file:
/usr/local/avamar/var/ddrmaintlogs/ddrmaint.log
The ddrmaint.log file is rotated when it reaches 25 MB in size.

In steady state, what is the approximate rate of data removed from an Dell Avamar grid during a daily garbage collection?
- A. 10 GB per hour per grid
- B. 100 GB per hour per grid
- C. 100 GB per hour per node
- D. 10 GB per hour per node
Answer: D
Explanation:
Explanation/Reference:
http://gregandthenetwork.blogspot.com/2013/12/design-imapact-of-avamar-system.html Garbage Collection is the single most important process to ensure a consistent state of the Avamar. If garbage collection is running, the system is in a read-only state and no other maintenance or backup can run.
Coincidentally, if backup is still running, garbage collection will not begin. Garbage collection can free up about 10GB/node/hour once the Avamar is in a steady state, but this will take longer as utilization of the Avamar grows.
