Instead of letting your DataDomain replicate your primary storage pool to your offsite location, you instead have two copy pools, one of which is off-site?
I can see some advantages to using a copy storage pool on-site as well as the primary storage pool, but why not use the DDR to replicate the copy storage pool to off-site instead of defining the second storage pool to TSM? DDRs are good at replication, and doing it this way would simplify your TSM processes (and, presumably, scripts).
