9.2.2 How csstored Works for Backups in a Calendar Server 6.3 System

One of the Calendar Server services launched at startup is csstored. When configured, this service performs automatic backups (either hot backups or archival backups, or both) of your calendar databases.

You can configure csstored for automatic backups when you run the configuration program, csconfigurator.sh. If you choose one or both of the automatic backups at that time, no further configuration steps are necessary.

If csstored is disabled, none of the other daemons that access the database will work. The csstored daemon performs other necessary tasks for the databases. Therefore, the daemon should not be disabled.

When automatic backups are disabled, the circular logging ics.conf parameter, caldb.berkeley.circularlogging, should be set to "yes". This enables purging of old database transaction logs, which conserves disk space.
