I do like RAID5 systems, with hot swap capability and automatic re-striping
of a replaced HDD. Those have worked well. But if the RAID controller
innards go bye bye, you are right, one is totally screwed without a good
backup (and image if it is a boot array). RAID is really good for
increasing reliability and performance as well in the correct
configurations, when it comes to the ability to survive the loss of a single
HDD in an array. But it does nothing to assure me of the ability to scrap a
backup/imaging strategy.
