Hard Disk Cloning in Linux

dd command does not copy files only it copies blocks also.

To make a clone of a hard disk /dev/sda on an empty hard disk /dev/sdb type the following command

dd if=/dev/sda of=/dev/sdb

Note:-

• here if specifies input file and of specifies output file.
• Wait untill the command is finished.
• Finally you will have an exact copy of the hard disk.
