This page lists host groups, each of which is a set of hosts that can be
simultaneously backed by a single Bacula Group Backup Job. The hosts
in a group are taken from either an OCM Manager node group database or the
Webmin Servers Index module, depending on the configuration of this module.
For bacula group backups to work, each must have at least the Bacula file daemon
installed, and all hosts in the group must have the same password for this
director.
