How to copy a RedHat disk image?

Question

Red Hat Enterprise Linux

This, of course, is very Nubian, but urgently needed.
There is a ready-made configured server, it is necessary to copy the system to its clone, otherwise I toiled with Makovsky hfs + for a very long time and was reluctant to repeat the rake campaign. Thank you.

dd if=/dev/sda1 of=/dev/sdb2 bs=4096 conv=noerror
