Sorry Craig -- didn't see your reply earlier.   Bernd's just brought it to 
my attention.   Certainly looks attractive, will give it a go for 
sure.   So on the "replay" side when you want to rebuild a server (or 
workstation) partition I presume you boot from a rescue floppy and reverse 
the process a la
cp /dev/st0 /device/and/partition/to/restore ?

Would "dd" have advantages or is "cp" safer because it makes no assumptions 
about good/bad sectors on the disk?

Cheers,
