# Short-Description: Bareos File Daemon
# Description:       Bareos is a network backup and restore program.
#                    The Bareos File Daemon backup the local system
#                    on behalf of the Bareos Director and
#                    sends the data to the Bareos Storage Daemon.
#                    It also receives data from restores.
