# Globally disable recordings in BigBlueButton

# set in /usr/share/bbb-web/WEB-INF/classes/bigbluebutton.properties by overwriting 
# it in /etc/bigbluebutton/bbb-web.properties - 
#
# set disableRecordingDefault=false to disableRecordingDefault=true for globally disabling 
# recordings. 
#
# Furthermore, recording of breakout rooms should be disabled by setting 
# breakoutRoomsRecord=false. In general, this is an advisable idea (independently of 
# disableRecordingDefault=true, because break-out rooms might imply a certain level of 
# privacy for typical users.
