You want a simple point-and-click GUI backup tool instead of a command-line-oriented live environment.

What is Clonezilla?

Clonezilla is a free and open-source partition and disk imaging/cloning program, similar to commercial tools like Acronis True Image or Norton Ghost, used for system deployment, bare-metal backup, and disaster recovery. It supports numerous file systems such as ext2-4, NTFS, HFS+, APFS, UFS, and VMFS3/5, and works with both MBR and GPT partition tables. The project offers Clonezilla Live for single-machine backup and restore, and Clonezilla SE (server edition) for massive deployment to many computers simultaneously using multicast or BitTorrent. It supports LVM2 volumes, LUKS-encrypted partitions, AES-256 image encryption, boot loader reinstallation, and unattended command-line operation, and can save or restore images to local storage, SSH, Samba, NFS, or WebDAV. Clonezilla is licensed under the GNU General Public License version 2 (GPLv2).

Carbon Copy Cloner

Carbon Copy Cloner

AI-suggested

Carbon Copy Cloner (CCC) is Mac backup software from Bombich Software that creates bootable clones and scheduled backups on drives the user owns, rather than a proprietary cloud service. It supports hourly, daily, weekly, or on-demand backup schedules, and its SafetyNet and Snapshot features preserve deleted or modified files so earlier versions can be recovered later. CCC can also back up cloud-only files from iCloud Drive, Google Drive, Dropbox, OneDrive, and Box down to local storage, and it verifies backups with checksum validation for data integrity. It is sold as a one-time $49.99 Personal and Household license covering every Mac in a household rather than a subscription, with a 30-day free trial and discounted upgrade pricing for existing owners.

Rescuezilla

AI-suggested

Rescuezilla is a free, open-source disk imaging application that provides a friendly graphical front end for Clonezilla, letting users back up, restore, and recover a full system even when it cannot boot into its regular OS. It boots from a USB drive or CD/DVD independent of the installed operating system, so it works across Windows, macOS, and Linux machines alike. It supports device-to-device cloning without a third drive, reads and writes formats compatible with VirtualBox, VMware, Hyper-V, and QEMU, and can mount disk images to browse and extract individual files without doing a full restore.
