Here was I use, and I have been shooting digitally only since Jan 2000. No lost files.
I use a Power Mac G5 and a HIghpoint PCI-X RAID card. I have 4 2TB drives but the card can handle 8 drives.
I have 4 drives plus the boot drive in my G5 and they are set up at a 6TB RAID 5 array. I have a second identical system as a back up.
1) cards come into the studio and RAW files are copied to the main server, edited, color corrected renamed and processed for proofing. At that point the job is copied to the back up server and also a set of DVD's are burned to file in the clients folder. The CF cards are then returned into service.
2) Back ups are updated as needed, not daily because often something is damaged due to human error, but it is nice to go back a few days or so.
3) about 6 months after the album is delivered and the job is done, I will burn another set of DVD's and remove the event from both servers.
There are times that I will be a week or two behind editing so I will store a back up set of files unedited just until I get to it.
In 13 years plenty of drives have failed, but loosing two drives at the same time to kill and array has never happened. If something really bad does happen, I can go back to the DVD's and start over.
The RAID was set up made years ago, first with 8 400GB drives and later updated with 4 2TB drives, and I may move to 3TB drives this year. I can fit 5 drives inside my Power Macs so I can add more drives to thecurrent array but that means external cables which I would like to avoid.
