OK.  The tests I've done shows that incrementals backups are compared to the
full backup within the class, not other classes, for Unix clients.

Ahh! Archive bit.  I was speaking to unix clients but there may be
difference between NT clients and Unix clients.  (Unix has no archive
bit...).

Yes, please let us know.  Someone else asked me who it was I got this
info from.  After going over my notes it turns out it wasn't Veritas
direct but a VAR SE.  He said it was a function of the OS as to atime
and archive bit settings.
