Seriously.
With NetApp or EMC ... the one's I'm familiar with ... once you've written to the head you can just ignore it ... questions about stripping, mirroring, RAID, etc. are irrelevant. The head takes full responsiblity for reading, writing, and recovery.
I've also come to the point where I think backing up to tape is a ridiculous waste of time and money. These days you can back up to hard disks far faster and for the same money. Fill a disk, pop it out, replace it with another. Recycle hard disks not tape.
