We have dueling V9000 data stores, one at a DR site several miles
from our main office. They talk to each other using IBM's v9000 to
v9000 replication. This is totally invisible to the LPARs on our
primary system-- it's all done by the storage systems.
In our case, the remote location is normally just receiving data, but
the LPAR is not 'awake.' In a disaster, we will IPL the LPAR. Since
the primary copy failed (for whatever reason-- maybe a plane landed
on the building), the IPL will be about 2 hours-- IPL after an
abnormal termination.
Our backup to tape is on our primary system. We make a flash copy of
the primary LPAR, and do an option/21 backup on the flashed copy.
Tapes go offsite using an 'offsite storage company.' In our case,
the office is all working off-site, except for our night-time
computer operator. He shuffles tapes for pickup by the offsite
storage company.
Our tape rotation is 35 days-- at month end the backup tapes are
archived off-site almost forever. No special backup, we just grab
the month-end option/21 tape, and add more new tapes to the rotation.
