Mark,

Thanks for that clarification.  That matches what I've seen on the
"archive" side of the system.

No, the oldest version of the file doesn't just roll off. You have to
run an inventory expiration to delete the pointer to the old file; once
the pointer is deleted, and you meet your reclamation threshhold, the
file indicated by the expired pointer will vanish when the volume it
resides in is reclaimed and reused.
