When attempting to retrieve remote backups from a target Avamar server using the Management Console Server (MCS), MCCLI, or the Avamar Administrator UI, it may be extremely slow to load available backups from the restore tab. The mcserver.xml value of get_backups_from_external_server is true: grep get_backups_from_external_server /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml <entry key="get_backups_from_external_server" value="true" /> If the setting is false, this article does not apply. Select a client and run the following commands as a benchmark: time mccli backup show --name=/<full-path-to-client> time avmgr getb --path=<full-path-to-client> --retention-type=none,daily,weekly,monthly,yearly time avtar --backups --path=/<full-path-to-client> --retention-type=none,daily,weekly,monthly,yearly Compare the times provided. If the avtar and avmgr are fairly quick, and the mccli is significantly slower, then the cause and resolution described below may be relevant.
MCS, mccli, or the UI are trying to retrieve backups from the remote grid instead of the local MCS database (MCDB). The avtar and avmgr commands query the Avamar GSAN whilst mccli and the UI query MCDB. If MCS is configured to retrieve the list of backups from the remote server instead of the MCDB, this can sometimes cause a large time lag.
Change the value of the parameter get_backups_from_external_server in mcserver.xml from true to false and restart MCS: 1. Log in as admin on the Avamar Utility Node. 2. Make a backup copy of the existing mcserver.xml file: cp -p /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml /usr/local/avamar/var/mc/server_data/prefs/x-mcserver.xml.`date +%y%m%d` 3. Using vi, edit mcserver.xml: vi /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml 4. Using vi, edit mcserver.xml: From: <entry key="get_backups_from_external_server" value="true" /> To: <entry key="get_backups_from_external_server" value="false" /> 5. Exit and save the file. 6.
