Kaltura CE backup


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 ?


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