I used Clonezilla again last night to clone my Windows 7 hard drive. It is prudent to keep a clone of Windows, because that operating system takes an enormous amount of time to install and configure. A conservative estimate would be twenty hours in total. I don't want to lose another twenty hours due to hard drive failure or malware infection, so Clonezilla gave me peace of mind by creating a bootable backup. There is no cloning feature built-in to Windows 7, and the backup feature I think is a joke. I don't work with backups, I work with clones. A clone is a byte-for-byte copy of a hard drive. If a drive won't boot, it's not a clone. A clone can be popped right into a computer with a failing hard drive and make it whole again in less than one minute. A clone is what the end user wants and needs. The end user is always right.
I doubt whether a clone could be used long-term to pirate Windows 7, because the operating system binds itself to the motherboard and cpu. Also, Windows phones home on a regular basis to confer with Microsoft headquarters and tell if the user is doing something naughty. My interest is not in piracy, because quite frankly I don't want Windows on any of my other computers--yuck, what a thought. I just need it on one computer to run two specific applications that are not available in Linux, ACDSee and Call Clerk. All the other computers are going to be running a flavor of Linux Mint Nadia, either KDE or Xfce.
