As a State agency, it's the time we ask for money for the
upgrades/replacements for the next year or two.
Our z800-0B1 lease runs out and so we'll be looking at z9BC. We also
have EMC 8230(?) dasd and 3590-A tape drives. A couple terabytes active
data, and more in migration/backup, etc. We're pretty small.
We have no mirroring at this time, we move tapes back at forth from a
vault on the other side of campus. The administration seems willing to
allocate funds for a more robust Business Continuation infrastructure.
It's been suggested by the Operations Manager and also my boss(es)
that we move to a "tapeless" model. That is that we acquire sufficient
dasd and establish a mirror offsite. We would cease DFHSM migration and
do FDR or DFHSM version backups to dasd.
It appears the tape might be more expensive than disk. And you don't
need people to mount disks. We don't have a silo.
The questions I've been asked to ask are: Is anyone else doing
something like this idea? Does it seem feasible? Or is it a really bad
idea?
I'm asking here because this seems a place to get some good thoughts
on this fast. My Director needs to talk with her VP next week, or maybe
the week after.
