You're talking about sparse files?
you seem to be subscribing to the 'its easier to do it all in one line'
approach. don't do that.
1) dump: dd if= of=imagefile.iso
2) compress: bzip2 -z imagfile.iso -c > imagfile.iso.bz2
3) send: scp your_usern...@remotehost.edu:imagefile.iso
/some/local/directory/imagefile.iso.bz2
4) decompress

its cool as long as you use a lossless compression format like bz2

Hi,
I need to transfer a local raw image to another datacenter.
Is there a way to achieve good compression of this image, I heard of
tools overwriting unused space with zeros. Is this a good idea?
It's an W2k8 image/NTFS.
Thx
