Wouldn't it be simpler to pick a random saveset on the nights backups
and then attempt to just clone it to another tape?  This should verify
the saveset and that you've got a good backup.

It's important to note that using nsrclone to clone your backups DOES NOT check that your backups are good. This checks to ensure that your original backup media is good, and can be read back from. It doesn't guarantee that the data that was backed up is usable in a recovery scenario.

There's two key styles of tests in this scenario: media testing and functional testing. nsrclone is a very good media test utility in this scenario (as is, for that matter, scanner). True functional testing however is only going to be achieved through actually recovering and confirming that the data is usable.
