Kaltura CE backup

Hi,

I’m thinking to inform our users on the Kaltura CE (6.2.0 dev) we have, and let them stat using it to load their video.
Before doing so, I want to make sure I can backup/restore their stuff in case of disaster.
I searched the forum and find some nice help like the following http://www.kaltura.org/upgrading-ce-5-ce-620 - but this came from the good will
of the forum members and not from Kaltura officials. Does kaltura CE (or the commercial version) has a built in command for Backup ?
How do I make sure the I’m using the right backup/restore method ?

Thanks,
Alon

What services do I have to stop when I will restore (follow steps you described above)?
