You're on the right track...

1. VE/VD/RE/RO parms would be */*/42/42 -- that gives you point-in-time
restore for any file over the past 6 weeks;  do the math, and monitor the
actual usage -- most shops experience less than 10% turnover per work-day,
we did our sizing based on 5% (even that was abit on the high side).  Using
these parameters gives you exactly what you have today, without re-sending
files that don't change (using the "standard" progressive incremental backup
in TSM)... and you'll save over 90% of tape real estate in the process!

2. Monthly backup sets, with two year retention;   this gives you the
monthly snapshot of all "active" versions -- again, exactly matches your
current situation -- and, again, without sending the data over the network.

Hope this helps.
