Neither RAID or rsync provide "data security".. in fact no tool or hardware does, that's a very dangerous mindset to adopt.. deep trouble ahead :-) .. now, that being said.. RAID can provide you much better *availability* and disaster recovery aid when things go wrong, but there is almost always a tradeoff for performance.
I'm sorry, but the accepted tenets of "Security" include the C-I-A triad: - Confidentiality - Integrity and - *Availability* http://en.wikipedia.org/wiki/CIA_triad#Key_concepts <quote> For over twenty years, information security has held confidentiality, integrity and availability (known as the CIA triad) to be the core principles of information security. </quote>
It is not a replacement for backups, that's when rsync comes into play to help the file transfer/sync process.
Correct: as has been pointed out by a number of people including myself, backups are another aspect of security - Integrity. You can also view backups as Availability post catastrophe :-)
"data security" involves a "process" not only "a bunch of hw and software" but also policies regarding physical/virtual access to the information, data retention and confidentiality.
True, but once we get into that we start dealing with issue like business alignment and policy enforcement and revision and ISO27000 and rapidly go beyond the scope of this list. If you want to go there, I can recommend some very active and very serious-minded lists; but this is about SUSE, not INFOSEC or ISO27K or POLICY.
Yes, cheap-ass hardware fails and usually sucks..but human beings screw things up in a much larger scale..big time! so think before you type ! ;-)
All hardware fails. No-one has an infinite budget. Yes, humans are the #1 security threat. But take away the humans and there's no point in having the computer systems, is there. Ultimately as the OP made clear, its about what management wants. As engineers, we know how to make indefinitely reliable systems out of unreliable components; that's what engineering is about - we're Sons of Martha[1]. Well maybe you're not; maybe you're a Son of Mary or Chicken Little.
