My current client has a V2X2 and is thinking about replacing it with a
Shark. SnapShot is used to snap 600 volumes in about 5-10 minutes. The
physical tape backups are done from the snaps and take about 8 hours.
This
DR process is fully tested and works great. My main concern if we
replace
the V2X2 with the Shark is the DR process. Has FlashCopy improved to
the
point that you can make a point in time backup and physically move it to
tape later? And can you FlashCopy the entire box in a few minutes? If
not,
the DR process for this client is going to get much more complicated.
It is feasible, however FlashCopy is worse than Snapshot. It takes more
real disk space, it is slows down the dasd box.
PPRC
or XRC are not options due to cost. Let me know your thoughts.
PPRC need not to be expensive. Obviously it requires two dasd boxes and
link, but gives you much better RTO and RPO.
