I would look into akronis as SEP suggested. Building the rpm may or may not have bugs associated with it. Pius getting support may prove difficult. I am actually going to look into using akronis after looking at the product page. Looks useful, plus it's a red hat certified piece of software.
"The difference between me and you? I will read the man page." and "Respect the hat." and "You could just do a search on ITRC, you don't need to start a thread on a topic that's been answered 100 times already." Oh, and "What. no points???"
