I was reading recently some extraordinary claims about how SIS made a
zillion gigabyte backup fit into a matchbox ... or something similar.

I have seen SIS at work in RIS (Remote Installation Service) where you can
store several instances of a Windows installation in a partition, and SIS
does some terrific magic to replace duplicate files with links.

But I wonder how SIS can be so effective when backing up general data. Do
we lusers really have so many duplicate files??
