An EMC Avamar server is integrated with an EMC Data Domain system.

Explanation/Reference:

Server maintenance activity monitoring

Avamar performs the system maintenance operations for backup data on the Data Domain system, includingHFS 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-nodeserver, during Avamar server installation. The ddrmaint utility is not installed on the data nodes of the Avamarserver.

The ddrmaint utility logs all maintenance activities on the Avamar server in the ddrmaint.log file. Thefollowing directory on either the utility node of a multi-node server or the single node of a single-node servercontains the log file:

/usr/local/avamar/var/ddrmaintlogs/ddrmaint.log

The ddrmaint.log file is rotated when it reaches 25 MB in size.
