We also keep 2 copy pools - one in the offsite vault, one on site - for some
of our ADSM storage pools.
The ones with highly reliable media, we only have the 1 copy pool offsite,
because we only need to get a tape back about twice a year.
The ones that use less reliable media, we keep a copy pool onsite for
recovering the bad primary tapes.
