Reading one of the editions of the Nemeth's book (Nemeth et al), have read about
volcopy -- an utility that copies a filesystem from one device to another, making "a literal copy" (here's a man page, though not too helpful).
The Book said the utility exists for Linux, but quick googlin' didn't show many results. So the question is -- is it used on Linux, and if not, what is the default alternative to mirror-copy a filesystem ?
Edit. I was thinking that such an utility could be useful in the case of e.g. hard disk replacement -- currently I am using
dd to replicate the root partition etc, this is fast but obviously preserves the size of the partition.
So I thought
volcopy could be a quick alternative that allows to copy to a bigger partition.
restore allow to to that, if I am not mistaken. Sorry for being too unspecific initially.
