IMHO,
Use a tape drive that doesn't require a special driver.
tar -C /new -xvzf /dev/st0 should "just work"
Other options:
Snag a knoppix iso and add the driver and rebuild. Then you have a
bootable CD to recover with.
Same but with a spare HD
For the PHB:
Q: A new tape drive, didn't we just buy one?
A: How much would it cost to recreate all the data from scratch again?
A: How much revenue would we lose because the data was not available for
a week (vs half a day with a regular tape drive) ?
For you:
Test a full bare metal restore _before_ it becomes necessary

Let's face it, there's no Hollow Earth, no robots, and
no 'mute rays.' And even if there were, waxed paper is
no defense. I tried it. Only tinfoil works.
