Let’s assume I have a hard drive with some linux distribution on it. My task is to set up similar system (with similar distro, kernel version, software versions etc.) on the other hard drive. How can i do that if:
Case a: I’m allowed to use any software i want (include software like Virtualbox to make full image of the system)
Case b: I’m not allowed to use anything but standard linux utilities to retrieve all characteristics i need, and then install “fresh” system on other hard drive manually.
Thanks for reading. It’s very hard to me to express what i mean, i hope you understood it.
Easiest way is to use dd from the command prompt.
dd if=/dev/sda of=/dev/sdb –bsize=8096
dd (the disk duplicator) is used for exactly this purpose. I would check the man page to ensure my blocksize argument is correct though. The other two arguments are if (in file) and of (out file). The of= hard drive should be the same size or larger than the if= hard drive.
