We were talking about what "safe" is. If you want to safeguard your data against your own mistakes, RAID is certainly not the right tool. A pair of big gardening gloves might be better :-)
And filesystem crash, and file corruption. Don't forget both.
If my data is so important to need a raid, I absolutely must also have an rsync backup. If I can't have both, then it will only be the rsync copy.
Your rsync copy still isn't as good as your RAID "copy". The rsync copy is always older, so you will always lose data when you have to use it.
Which is why it should be both. But the problem is that many home users set up raid, because their main boards have it, in the belief that it makes their data safe. It doesn't. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
