While an unqualified Exclude should intuitively exclude a file system
object from all TSM operations, the product unfortunately departs from
obviousness here, requiring the .archive
qualifier to exclude from archiving as well, as has been consistently
explained in the client manuals. Products sometimes have warts like
this due to the way they evolve from initial design objectives, as in
Backup being the initial role of the primordial product.
