I interpret it to mean, the par stuff means you can suffer up to 5%
corruption by volume of data: so, if you had 100GB, up to 5G of that could
be corrupted and you could recover it.

In practice this probably means that you can recover from the majority of disk problems - unless you get particularly unlucky you're likely to be able to recover from some damaged sectors, and whole disk failures are generally unlikely (I've *never* seen one that wasn't caused by massive physical trauma).

Well, there is also the popular "disk controller board just stops working" failure mode.

Let's rather re-prhase that as:

"You should be able suffer up to 5% corruption of the backup files, and
still be able to restore all your data".
