Clonezilla ou Acronis True Image : une bonne alternative sous Linux ?

Clonezilla, alternative Linux à Acronis True Image

Mis à jour le 20 octobre 2026

Notre avis

Clonezilla is a solid replacement for Acronis True Image if you're comfortable with Linux and don't need point-and-click simplicity. It handles full disk imaging, cloning, and incremental backups reliably, and supports scheduling via scripts. However, it lacks a graphical interface and built-in ransomware protection. It's ideal for technical users or system administrators who prioritize control and cost over ease of use. If you need automated, hands-off backups with minimal setup, Acronis remains easier. Clonezilla excels in enterprise or lab environments where deploying identical images across multiple machines is common.

Ouvrir vos fichiers Acronis True Image

Clonezilla cannot read or restore from Acronis True Image .tib files. The two tools use incompatible image formats. If you have existing Acronis backups, you must restore them using Acronis software before migrating to Clonezilla. Once switched, Clonezilla stores images in a directory structure with optional compression, which can be restored only by Clonezilla or tools that understand its format (like partclone). There is no direct import path from .tib to Clonezilla’s format.

Questions fréquentes

Can I use Clonezilla to back up a Windows system?

Yes, Clonezilla supports NTFS and can image and restore Windows systems. Boot from the Clonezilla live USB, select your Windows partition, and create an image. You can restore it later to the same or different hardware.

Does Clonezilla support encryption for backup images?

Yes, Clonezilla supports image encryption, but only when used with SSH or an encrypted remote server. The backup image itself isn’t encrypted by default—security depends on your storage setup.

How do I automate backups with Clonezilla?

Clonezilla doesn’t have a built-in scheduler. Use a Linux system with cron and a script that boots Clonezilla automatically via PXE or a headless setup, or manually run backups from a live environment using saved configurations.
