There's only one /ora in his dump summary...I was working on the assumption
that the output from df at the beginning of the message is the same
partition. It looks to me that it is an ~8.7GB partition with ~6.8GB in use
and ~1.8GB free. Obviously 6.8GB isn't going to fit on a 4GB tape, but
compressed it might have at one point in time. It's just not anymore.

So the way I see it he'll have to split /ora up with tar, no?
