RE: Is there a Linux ghost?




You are right,
but just remember that "ghost" is a program -intended- to do disk
duplication.
dd is simply "general purpose" block copy program, so it is possilbe to
duplicate disks with it,
but because of it's general nature, it's doing it "stupidly", hence, copying
every single block.

If u want some sophisticated disk copying, with special optimizations, and
not just block copying, u should seek for some other program to do it.

The whole point is that dd can do it, but it can be done better.

As I recall dd will make an image of 20 GB from 20GB HD even if the HD has
only 1GB data
while ghost will store only the 1GB from the 20GB HD and will be able to
restore it to any HD larger then 1GB.

Am I right ?
