Clonezilla is an open source software designed for creating disk images (imaging) and cloning disks. It is widely recognized as a free and reliable alternative to paid products such as Symantec Ghost® and Acronis True Image®.
The software offers basic applications including backup (creating complete copies of working systems), migration (transferring operating systems and data to new hard drives), and deployment (installing the same configuration across multiple computers simultaneously).

Why It Stands Out
Creating Your First Disk Image
- Boot Clonezilla Live from USB or CD
- Select device-image mode
- Choose destination folder for image storage
- Select source disk or partition to image
- Confirm settings and start the imaging process
How This Would Help: Creating disk images provides complete system backups that can be restored quickly after hardware failure or system corruption.
Mass Deployment Setup
- Configure PXE server for network boot
- Set up multicasting for simultaneous deployment
- Prepare master image with desired configuration
- Use Wake-on-LAN to start target machines
- Monitor deployment progress through server interface
How This Would Help: Mass deployment saves hours of manual installation time when setting up multiple computers with identical configurations.
Cloning Between Different Sized Drives
- Use device-device mode in Clonezilla
- Select source and target disks
- Choose Expert mode for advanced options
- Enable -k option to resize partition to fit new drive
- Complete the cloning process
How This Would Help: Resizing partitions during cloning allows you to migrate to larger drives without wasting space or needing additional tools.

Notable Features
- Smart Copy Technology: Supports all popular file systems including ext2/3/4, NTFS, FAT32, and HFS+, copying only occupied data blocks to save time and disk space.
- Universal System Support: Uses sector copy (dd) for unknown file systems, guaranteeing 100% accuracy even for unsupported operating systems.
- Live Version for Single Machines: Runs as a live disc/USB that can be installed on flash drives, supporting both local and network backups via SSH, Samba, and NFS.
- Server Edition for Mass Deployment: Ideal for corporate environments, using Multicasting, PXE, and Wake-on-LAN technologies to deploy to dozens of computers simultaneously.
- Windows Environment Integration: Through drbl-winroll package, automatically changes computer names, SIDs, and workgroups in Windows environments during deployment.
- Security-Focused Operation: Runs in its own Linux environment without leaving traces in the host computer’s operating system.
