First let me say I really agree with Andrew.
That being said, I believe "robocopy 2003" has the ability to copy data based
on last modified and last accessed dates. You can do either or both I believe.
In order to accomplish what this customer wants you could first copy the stuff
out using that feature, delete all the data and then copy it back. This is of
course extremely risky so I would back it up first which would seem to negate
the whole process. However, if your nice you could back the data up
temporarily to a new node name of filespace and then if everything works after
the delete and the copy back you could purge the data from TSM by deleting the
node or filespace.
Anyway, I've seen a similar request when moving data to new hardware. I've had
a few customers clean house this way. Still, in all those cases they said
"back it up first" so if we need it we can get it.

There is no filtering option in TSM to do this.
Using the age of a file to determine whether to back it up is, in my own
opinion, ill-advised. If the customer does not care to back up these
files, then why not simply "cut to the chase" and delete them? After all,
if the disk were to be lost tomorrow, they wouldn't be recoverable. If the
customer balks at the idea of deleting them outright, then that would
suggest a re-think of the backup strategy (what would the customer's
reaction be if someone actually did this?) The good news is that if the
files don't change, TSM's incremental approach will only back them up once
(okay, twice if you back up your storage pools, which is recommended).
Of course, some of these files are probably junk or temporary files that
are no longer needed, in which case it might be worthwhile to comb through
those files and clean up the truly unneeded ones.
Just my own thoughts on the subject. :-)

The only dumb question is the one that goes unasked.
The command line is your friend.
"Good enough" is the enemy of excellence.
