For perspective: Under ordinary conditions of TSM usage, employment of Delete 
Volhistory with a date is common and desirable for pruning old stuff and 
reclaiming media.  It's commonly done for TSM database backup tapes (where DRM 
is not in play).  The older the data, the less viable it becomes, and the more 
desirable to dispose of it.  Export data is, in most cases, transient, where it 
is Imported into its new home as soon as possible, where it is subject to 
standard safeguards, including multiple assurance copies.  The export media 
then become superfluous.  On occasion, Export may be used to create a snapshot 
of a node's data, as an out-of-band measure, as in getting a node off your 
system but keeping its content around for a while, just in case some 
circumstance may require its resurrection.  Again, that constitutes a singular 
copy, with attendant risks.

I think those of us who have come to depend upon the date function of Delete 
Volhistory have found it reliable.
