ZMC provides Event logs so you you can all the events and take corrective action if necessary. All events related to backup (but not restore events) are presented in a tabular form. The events can be sorted on any column by clicking the column header name.

The columns of the page are:
Alerts can also come from Zmanda Network, providing security and product updates. The ZMC can generate many events during a backup process and configuration process.
All events are retained until purged using the logrotate utility (described below). This lets backup administrator identify error trends across backup runs.

ZMC works with a log rotate utility that allows sysadmins to effectively prune active logs.
Sysadmins should rotate the logs using crontab.
For example: 0 1 * * 1,5 logrotate /etc/logrotate.d/zmc_logrotate (For 1 AM on Monday and Friday of each week)
The pruned logs are not saved by the utility; they are simply pruned by it. You must manually copy the logs before pruning if you wish to retain them.
