Clonezilla vs FOG Project

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.

FOG Project is a free, open-source system for cloning and managing networked computers. It captures and deploys Windows, Mac OSX and Linux distributions, including hardware-independent images that can be used across different computer models. The project also lists multi-site installations and remote management, provided the FOG server is publicly reachable. That server must run on Linux; recommended options include server-oriented LTS distributions such as Ubuntu, Debian, Rocky Linux or AlmaLinux. FOG recommends configuring client machines to PXE boot first so imaging tasks can be sent without visiting each computer. The FOG Client supports host registration, hostname changes, scheduled power management, snapin installation and user tracking, with client installation described for Windows, Linux and OSX. Client-server communications use public-key infrastructure and AES-256 encryption after an RSA-4096 key exchange. The security guide recommends firewall rules and protecting the MySQL database and captured image directory. Community support is available through forums, a wiki and IRC. The Linux client lacks the FOG Tray, Active Directory joining and PrinterManager. FOG Project is free for commercial use; community support is free.
