Disk Space High for Recordings

[JarrodJay]

Hello,

I have one client using BigBlueButton for 60-90 minute sessions. Her recordings, however, seem rather large and significantly higher than what is mentioned at https://code.google.com/p/bigbluebutton/wiki/FAQ#What_is_the_disk_space_usage_for_storing_1_hour_of_recordings.

A 90 minute session uses:

- 92MB in bigbluebutton/recording/raw/[meeting-id]/video/*

- 475MB in bigbluebutton/recording/raw/[meeting-id]/audio/[meeting-id].wav

- 475MB in freeswitch/meetings/[meeting-id].wav

The video seems quite fine with webcam streams ranging from 5-30MB. However the audio seems exorbitant, plus it's duplicated in freeswitch and the bbb folder.

Ideally- the audio wouldn't be as bloated, and wouldn't need to be duplicated. Or perhaps something isn't performing correctly on this server?

Any help would be super appreciated!

Thank you,

Jarrod.

Hi,

I see that you're using BigBlueButton 0.9 beta. We've made some
changes to the way audio is handled in this version compared to 0.81,
so the "raw" audio files are larger and the older guidance doesn't
apply.

The main change is that the recorded audio files are now 48kHz stereo
instead of 16kHz mono, which is a significant size bump. This is due
to the increases in audio quality for the WebRTC media.

The files under /opt/freeswitch/meetings should be cleaned up
automatically after a few days by the cron job, but the files under
/var/bigbluebutton/recording/raw are not automatically removed.

If a recording has been processed successfully, and you are *sure*
that you will never want to reprocess it, you can safely delete the
files for that meeting under /var/bigbluebutton/recording/raw.

If you want to do this automatically, you may want to look into
writing a "post publish" script (a new 0.9 feature), see
https://code.google.com/p/bigbluebutton/wiki/090Recording#Writing_Post_Scripts
which would delete the raw files after the recording has been
published.

Calvin.

Hi Calvin,

Thank you for the reply! (I missed that you had replied)

I've just solved my problem with the duplicated audio- cron wasn't installed at all, so the daily cron wasn't even running.

Thanks Calvin,

Jarrod.
