Another issue with disk-based backup, is that you use the entire disk,
because it is random access. That means you can access any point on
the disk in the same amount of time.
For example, if you have 200 GB of backup each night on your AS/400,
and it compresses 8 to 1, you can keep over a months worth of backups
on a 1 terabyte hard drive.
The objects stored in IBM midrange libraries tend to be compressible
up to 8 times, this means a portable, USB pow3red hard drive can be used to make an
offsite copy of up to a terabyte of IBM AS/400 or I5 data - for a
cost of about $100.

has anyone request d2d2tape or express any feelings
regarding that point or is it a non-issue?
tape seems pretty dead to me.

and by the way, try and use a larger font when you post, Boy Wonder, I had to go through and edit the HTML by hand.

You know, one of the main ideas of LVB is that you can copy all those generations of backup for disaster recovery and take it offsite. You guys should mention that.
