Re: External disk for iSeries

Look into the new fiber-attached Ultrium 2 tape drives. If you're on an 8XX box or later, the transfer rate is probably faster than moving it to another server. Each tape cartridge holds 200GB of data uncompressed, 400 GB with compression.

libraries perhaps)



This is what I would like to do:

1) Restrict the system
2) Back up the entire system (complete image) to another set of disk drives
3) Bring the system back from a restricted state
4) Transfer from this 2nd set of disk drives to tape

Can this be done?  Wouldn't this be a lot smaller restricted window than any
tape backup?  Would this be a lot more expensive than having 2 tape drives
to duplicate tapes for offsite storage?  Is anyone already doing this?
