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 Rainer
I'd use dd if=<local dev> | bzip2 | ssh <remote user>@<remote server> "bunzip2 | dd of=<remote dev>" or something similar.
I'd then do ssh <remote user>@<remote server> "md5sum <remote dev>" ; md5sum <local dev> to give myself some reassurance that they were the same.
