HPUX backup (sorta working)

ISL lives in the LIF volume which is not part of a partition.
You can probably make your exact image if you use the device for the whole
disk rather than backing up by partitions. The whole disk device should
get all the partitions.

A man lif on your 10.20 system should provide some info.
