Remember RAID isn't a replacement for backups. I back up regularly to a second RAID0 array, and also a removable hard drive. To lose my data completely the following sequence of events would have to happen (without any replacement/rebuild in the meantime)...
- two drives in the RAID5 array fail
and
- one drive in the RAID0 array fails
and
- the external drive fails

That's a little overkill for me, that is why I would rather backup to a non-live medium like tape or dvd - and I can have months or years worths of full backups without having to worry about space. I need at least up to 6 months worth of backups because every now and then a file that you hardly use gets corrupted and if you only have backups up to a month or 3 backwards you won't be able to restore that file when you finally figure out it's bad.
But hey if it works for you thats great!
