View Options

# ConfigurationSetting class describes a model that keeps the current Bacula
# configuration.
#
# It has some hard coded settings as defaults.
# Archiving's admins can enter new settings concerning:
#
# * jobs
# * clients
#
# and override the default ones.
#
# ConfigurationSetting is supposed to have only one record in persisted in the database
# which will hold the altered configuration as a patch to the defaults.
# Admins can reset this change at any time.
