Yeah.  They're files from Backup Exec.

Turns out what happened was I recently switched from using AIT1 tapes for the 
NT backups to AIT2 tapes.  However, I left the tapetype set at AIT1.  Once 
the backups got loo large for 2 AIT1 tapes  (runtapes = 2) amandam truied to 
get clever. :-)  I've changed the tapetype to AIT2 so everything should be OK 
from now on.
