The software is available as a hybrid image, which can therefore be launched from a USB-based storage medium. The ISO images each are less than 300MB and fit easily on CD-ROMs, allowing the tool to run on very old computer systems. While the alternative Ubuntu version exclusively serves 64-bit systems, the Debian-based version also offers two 32-bit versions, one of which supports processors with the Physical Address Extension (PAE). You control the complete system via ncurses menus.Ĭlonezilla is available in several variants. Developed in Taiwan, Clonezilla is based on Debian Sid or alternatively on Ubuntu 18.04.1 LTS and has no graphical user interface (GUI). The best known example of cloning software is the free live system Clonezilla. Network use is also good for rollouts, where the admin can fuel a large number of identically configured computer systems with the same operating system in a short time.
In larger organizations with centralized data storage, it also helps if the generated system images can be stored on an NFS or SMB system via FTP transfer or an external storage option with SSH access if one exists. In order to function in heterogeneous IT environments, the cloning programs also need to harmonize with older systems that still rely on conventional BIOS.įor systems with larger storage requirements, the applications also need to compress the generated images on the fly. They also must be able to cope with heterogeneous IT infrastructures, as well as support common boot managers and the Master Boot Record (MBR) and GUID Partition Table (GPT) layouts. In contrast to backup applications, which are typically implemented in desktop environments and back up the current system, universally deployable snapshot programs have to be able to handle various filesystems. One snapshot disadvantage is the increased time required for the application. Unlike a backup solution, a snapshot image does not require importing several backup layers. Unlike conventional backup sets, this unit cannot be supplemented and accelerated by differential or incremental partial backups.Īdmins can thus reconstruct the complete system in a single pass in case of a crash.
A snapshot usually includes a drive partition. Snapshot software differs greatly from backup software.
