Do you have a need to recover in case of a disaster? Having a vault on the other side of campus may or may not be sufficient.
Do you have a contract with a DR support site? If so, how will you get the data to the DR site if your mainframe is down and you have nothing on tape? I have heard of companies mirroring to a DASD device at the DR recovery site (although we don't do that) - we are state government also.

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. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
