Clonezilla is a very useful free open-source software tool because it can save you a lot of work time as a systems technician when installing operating systems on computers with identical characteristics. It also becomes miraculous in cases of disaster on a computer due to viruses and such. Once the data is saved, the computer can be restored to a freshly formatted state thanks to Clonezilla. All this is possible because by booting from a Clonezilla USB or DVD, a program starts that allows us to make an exact copy of our disk image, all from a pleasant and simple user interface. Even if it has an operating system installed. With the Clonezilla server version, you can even clone numerous computers over a network.

The Clonezilla application belongs to the category of applications that are part of the passive security software group, as it allows us to attempt disaster recovery or massive data loss. It is used for cloning disk volumes and their partitions. It is like the free software version similar to Norton Ghost, which means it will be free. Once the cloning of a disk, volume, or partition is done, you can save it as an image file and transfer it to a USB drive, DVD or CD, a NAS server via SSH, SAMBA server, etc. It also facilitates the work of installing operating systems with all the necessary applications integrated into many workstations with identical technical characteristics. This would be done by performing an initial installation and then cloning that machine. Instead of reinstalling the OS and all the necessary applications on each computer, you can clone that image on each workstation. But remember, they must be identical machines in terms of hardware resources!!

It is a system designed in Linux, so it is very stable and robust. It allows you to clone an entire hard drive or a partition of the drive to be able to recover it if needed. It can be run from USB, CD, DVD, and from the network to clone several computers simultaneously.
