linux – Copy entire file system hierarchy from one drive to another – Super User

I would like to copy the entire file system hierarchy from one drive to another..i.e contents of each directory as well as regular files in Linux platform. Would be gratefull to know the best way to do that with possibly Linuxes in-built functions. The file system is a ext family.
