From Fedora Project Wiki

Arno Lehmann

I'm mostly supporting Bacula, the open source backup and recovery package. Both for free on the project mailing lists and commercially.

Community Mailing lists

You'll find I read almost all the mail that is sent to bacula-users and bacula-devel at lists dot sourceforge.net. If you want to get support for your installation of Bacula, and do not require professional, commercial support, that's where you can find a great community with real in-depth knowledge and lots of experience.

Commercial

Yes, indeed. No advertising here, though.

Fedora

Well, I'm not really involved with Fedore Core. I run some test installations, and I do maintenance of Fedora Core installations, but that's about all... my contact with the Fedora Project is mostly my talk at FUDCon: Berlin 2009.
