Fortyoz,
Sometimes it is a little more complicated than that.
I have seen situations where raid towers have gone down and data from the stripe is un-reachable due to the fact the entire tower is down.
In these situations, it is imperative to have more than one source of backup, such as a second raid tower, tape drive, Ghost image, tape drive…..
I would be interested in what you feel are the best backup solutions as I am always looking for better ways to safegard not only my own data but also that of my clients. By all means, drop me a private message with your thoughts…..
