Cloning is nothing but the copying of the contents of a server hard disk to a storage medium (another disk) or to an image file. Disk cloning is quite useful in modern data centers for:

  1. Full system backup.
  2. System recovery.
  3. Reboot and restore.
  4. Hard drive upgrade.
  5. Converting a physical server to virtual machine and more.

In this post, I’m going to list the Free and Open Source Software for Disk Imaging and Cloning that you can use for GNU/Linux, *BSD and Mac OS X desktop operating systems.

Ansible Today I will be talking about ansible, a powerful configuration management solution written in python. There are many configuration management solutions available, all with pros and cons, ansible stands apart from many of them for its simplicity. What makes ansible different than many of the most popular configuration management systems is that its agent-less, no need to setup agents on every node you want to control. Plus, this has the benefit of being able to control you entire infrastructure from more than one place, if needed. That last point’s validity, of being a benefit, may be debatable but I find it as a positive in most cases. Enough talk, lets get started with Ansible installation and configuration on a RHEL/CentOS, and Debian/Ubuntu based systems.
