The moral of the story here is that if you want to be sure that your backup 
data is good....do a restore test.  Don't trust the bpverify function.

Bpverify "verifies" far less than you think it does.  The more I learned about 
it, the less interested I was in it.

If you use bpverify, it reads the media and compares the contents of the 
media to the catalog.

It does not verify the data itself, only the contents of the catalog as 
you said.

I have seen restores fail and bpverify says the tape is ok.
