Clonezilla vs Cobbler

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.

Cobbler is free, self-hosted Linux server software for creating and automating network installation environments. It supports PXE deployments, virtualization with Xen, QEMU/KVM, or VMware, and reinstallation of existing Linux systems. Administrators can coordinate DNS, DHCP, package updates, power management, and configuration-management orchestration. Interfaces include a command line, WebUI, and Python and XML-RPC APIs. Automated installation formats include AutoYaST for SUSE and openSUSE, Kickstart, and Preseed for Debian and Ubuntu. Templates and reusable snippets generate installation files and manage services such as DNS and DHCP. Cobbler integrates with cfengine3, Puppet, bcfg2, and Chef, or its internal lightweight system. It can be installed from distribution packages or source; pip installation is documented but not recommended. Python 3 is required, and server setup needs Apache, certificate, and administration knowledge. Security guidance notes broad network control and no SELinux or AppArmor profile. The project describes use in small and large installations.
