I didn't say you CAN'T.
I said you don't have to...(and in my opinion, you shouldn't)
You can have a single volume pool, and three groups of tapes within one
pool, all with different retentions.
In your case, if you write a 1 year retention to a tape, that tape is
tied up for a year....even though there's only a couple hundred megs on
it with a yearly retention, and 60 gigs with a 2 week retention...that 2
week retention data is stuck on that tape, wasting space for a full
year.
If you turned off the "Allow Multiple Retentions Per Media" option, you
would have a couple tapes for 1 year retained data, a bunch of tapes for
3 month retained data and a bunch of tapes with 2 week retained
data...and all in the same volume pool, if you so choose.
You would constantly have fresh scratch media available.
You'd have a hard time convincing me why you need to mix retention on a
single media.
