Clonezilla vs Iperius Disk Cloning

Clonezilla is a free, open-source program for imaging and cloning partitions and disks for system deployment, bare-metal backup, and recovery. Clonezilla live is suited to one machine; lite server and Clonezilla SE can clone many computers at once, with the site describing 40-plus computers. It saves and restores used blocks on supported file systems and uses sector-to-sector copying for unsupported ones. Listed file systems include Linux, Windows, Mac, BSD, Minix, and VMware formats, including ext4, NTFS, APFS, and VMFS3/5. Images can be kept on a local disk or SSH, Samba, NFS, or WebDAV servers, and can be encrypted with AES-256. Clonezilla SE supports multicast, while lite server supports BitTorrent deployment. Clonezilla live supports BIOS or UEFI boot and MBR and GPT. It requires an x86 or x86-64 processor, 196 MB RAM, and a boot device. The destination partition must be at least as large as the source. Differential and incremental backups and online imaging are not implemented; images cannot be mounted or explored for direct individual-file recovery.

Iperius Disk Cloning is a free Windows utility that makes an exact disk-to-disk copy. It runs inside Iperius Recovery Environment, which can start from a USB stick or optical media such as a CD or DVD. The maker describes it for moving an operating system to a larger disk or cloning a hard disk to an SSD. Disks connected directly to the machine and USB disks are supported. The destination must have capacity equal to or greater than the source, and the selected source cannot also be the destination. For hardware needing specific drivers, the utility can load an .inf driver while running, including for RAID controllers and SCSI devices. The recovery environment is WinPE-based and can be prepared on a USB drive or ISO file. The maker describes procedures for Windows 10 and 11 and says they apply from Windows 7 through Windows Server 2025. It can restore Iperius .VHD or .VHDX images, including on different hardware. Creating recovery media permanently erases the selected USB drive.
