EnglishHow Rescuezilla Disk Imaging Works for Backup and Bare Metal Recovery
Updated
Rescuezilla is an open-source disk imaging app with a graphical interface that boots from a USB stick or CD-ROM and is fully compatible with Clonezilla. It works by saving your entire hard drive as image files on an external drive, so if your drive fails you can restore your documents and settings to the exact state they were in when the snapshot was taken. It is the right tool when you want point-and-click backup and recovery, including on machines that can no longer boot into their regular operating system.
What disk imaging actually does
Disk imaging makes a backup of your computer's hard drive and manages that backup as files stored on an external hard drive. Unlike copying individual folders, the image captures the whole drive as a unit, which is what makes a full bare metal restore possible.
If your hard drive fails, you restore the disk image and within a few minutes all your documents and settings are returned to the exact same state they were in when the last snapshot was taken.
Why it works when your system won't boot
Rescuezilla is designed for recovery situations where the installed operating system is unreachable. It does not matter if you use Windows, Mac or Linux, and it does not matter if you cannot even log in.
The mechanism is a live environment:
- Download the ISO and write it to a USB stick.
- Reboot the machine and boot from that USB stick.
- Your computer loads a complete mini operating system with a point-and-click interface into memory, without writing any information to your hard drive.
- From there you run backup, restore and recovery actions against the internal drive.
Because nothing is written to the internal disk during boot, you can work on a failing or unbootable machine without disturbing its current state.
Compatibility and what you can do with images
| Capability | What it means for you |
|---|---|
| Clonezilla interoperability | Fully compatible with the industry-standard Clonezilla, so images can move between the two |
| Virtual machine images | Supports images made by VirtualBox, VMware, Qemu and all known open-source imaging frontends, including Clonezilla |
| Mounting images (beta) | Easily mount any supported image and copy out your files |
| File access without login | Access your files even if you cannot log in |
| Deleted file recovery | Recover deleted pictures, documents and other files |
| Live browsing | Internet access with a full-featured browser from the live session |
The Clonezilla compatibility matters if you already have images from other tools or want the option to restore with a different frontend later.
What you need before starting
- An external hard drive with enough free space to hold the image files.
- A USB stick (or CD-ROM) to write the Rescuezilla ISO to.
- The current download: Version 2.6.2, released 2026-05-15.
- No installation is required — it runs from the USB stick or CD-ROM and boots in seconds.
Where it came from, and why that matters
Rescuezilla was forked from Redo Backup and Recovery (now called Redo Rescue) after that project had been abandoned for 7 years. It is not a trivial fork: it was carefully rebuilt from the ground up to be fully compatible with Clonezilla. That history explains the combination it offers — the simple interface lineage of Redo Rescue with the image format compatibility of Clonezilla.
Choosing it, and one caveat
Choose Rescuezilla if you want the most features coupled with the simplest, most user-friendly interface, and you need recovery to work on a machine that will not boot. The project is GPL open source, and the site notes that all users should consider contributing $1/month on Patreon so development can continue — a signal that ongoing development depends on community support rather than a paid license.
