Right now, I'm evaluating and studying some open source available solution for backup and recovery.

I'm looking something that will be able to backup a heterogeneous operating system (Windows, Linux); database and applications like Oracle, MySQL, Lotus Domino; and clients like Windows 2000, XP, Vista - all must be automated, online and no user intervention, and if possible up to bare metal backup and recovery as well.

Any suggestions please? Thanks.
