Clonezilla vs iVentoy

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.

iVentoy is a PXE/HTTPBoot server for booting and installing operating systems on multiple machines over a network. It runs on Windows and Linux, with Linux server builds for x86_64 and ARM64. The maker lists more than 110 supported operating system types, including Windows, WinPE, Linux, Unix, and VMware. Client boot modes include x86 Legacy BIOS and IA32, x86_64, ARM64, and LoongArch64 UEFI. iVentoy boots ISO files directly without extracting them and retains their native boot menu style. It can install different operating systems on multiple clients simultaneously, filter clients by MAC address or architecture, and assign unattended installation scripts to ISO files. Its HTTP server can serve files inside ISOs without unpacking them. The server includes DHCP and can also use third-party DHCP servers, but DHCP Proxy is not supported. Secure Boot is supported, though client Secure Boot currently works only on x86_64. The Free Edition costs nothing, has no usage time limit, and allows up to 20 clients with no commercial use. Pro costs $49, paid once.
