A Linux distribution is an operating system made from a software collection that includes the Linux kernel and often a package management system. They are often obtained from the website of each distribution, which are available for a wide variety of systems ranging from embedded devices and personal computers to servers and powerful supercomputers.
Knoppix, stylized KNOPPIX, is an operating system based on Debian designed to be run directly from a CD / DVD or a USB flash drive. It was first released in 2000 by German Linux consultant Klaus Knopper, and was one of the first popular live distributions. Knoppix is loaded from the removable medium and decompressed into a RAM drive. The decompression is transparent and on-the-fly.
A live CD is a complete bootable computer installation including operating system which runs directly from a CD-ROM or similar storage device into a computer's memory, rather than loading from a hard disk drive. A live CD allows users to run an operating system for any purpose without installing it or making any changes to the computer's configuration. Live CDs can run on a computer without secondary storage, such as a hard disk drive, or with a corrupted hard disk drive or file system, allowing data recovery.
SystemRescue is a Linux distribution for x86-64 and IA-32 computers. The primary purpose of SystemRescue is to repair unbootable or otherwise damaged computer systems after a system crash. SystemRescue is not intended to be used as a permanent operating system. It runs from a Live CD, a USB flash drive or any type of hard drive. It was designed by a team led by François Dupoux, and is based on Arch Linux since version 6.0. Starting with version 6.0, it has systemd as its init system.
Puppy Linux is a family of light-weight Linux distributions that focus on ease of use and minimal memory footprint. The entire system can be run from random-access memory (RAM) with current versions generally taking up about 600 MB (64-bit), 300 MB (32-bit), allowing the boot medium to be removed after the operating system has started. Applications such as AbiWord, Gnumeric and MPlayer are included, along with a choice of lightweight web browsers and a utility for downloading other packages. The distribution was originally developed by Barry Kauler and other members of the community, until Kauler retired in 2013. The tool Woof can build a Puppy Linux distribution from the binary packages of other Linux distributions.
In computing, data recovery is a process of retrieving deleted, inaccessible, lost, corrupted, damaged, or formatted data from secondary storage, removable media or files, when the data stored in them cannot be accessed in a usual way. The data is most often salvaged from storage media such as internal or external hard disk drives (HDDs), solid-state drives (SSDs), USB flash drives, magnetic tapes, CDs, DVDs, RAID subsystems, and other electronic devices. Recovery may be required due to physical damage to the storage devices or logical damage to the file system that prevents it from being mounted by the host operating system (OS).
GParted is a GTK front-end to GNU Parted and an official GNOME partition-editing application. GParted is used for creating, deleting, resizing, moving, checking, and copying disk partitions and their file systems. This is useful for creating space for new operating systems, reorganizing disk usage, copying data residing on hard disks, and mirroring one partition with another. It can also be used to format a USB drive.
PhotoRec is a free and open-source utility software for data recovery with text-based user interface using data carving techniques, designed to recover lost files from various digital camera memory, hard disk and CD-ROM. It can recover the files with more than 480 file extensions . It is also possible to add custom file signature to detect less known files.
A live USB is a portable USB-attached external data storage device containing a full operating system that can be booted from. The term is reminiscent of USB flash drives but may encompass an external hard disk drive or solid-state drive, though they may be referred to as "live HDD" and "live SSD" respectively. They are the evolutionary next step after live CDs, but with the added benefit of writable storage, allowing customizations to the booted operating system. Live USBs can be used in embedded systems for system administration, data recovery, or test driving, and can persistently save settings and install software packages on the USB device.
Mondo Rescue is free disaster recovery software. It supports Linux and FreeBSD (i386). It's packaged for multiple distributions. It also supports tapes, disks, USB devices, network and CD/DVD as backup media, multiple filesystems, LVM, software and hardware RAID. Restoration may be done from a physical media including OBDR tape support, or CD/DVD/USB media, or from the network through PXE.
TopologiLinux is a free Linux distribution to be run on an existing Microsoft Windows system. The main feature of TopologiLinux is that it does not require any partitioning. It is based on Slackware and Cooperative Linux (coLinux). TopologiLinux has been chosen as one of nine open-source projects used as principal examples in a study of the characteristics of open-source software.
Software remastering is software development that recreates system software and applications while incorporating customizations, with the intent that it is copied and run elsewhere for "off-label" usage. The term comes from remastering in media production, where it is similarly distinguished from mere copying.
Partimage is a disk cloning utility for Linux/UNIX environments. Partimage can save partitions in many formats to a disk image. Utilities such as Partimage are useful in a number of situations which are commonly encountered by network administrators as well as advanced computer users who maintain their own systems. The last stable release was in 2010; since then, one of Partimage's authors has worked on FSArchiver, which has broader functionality than Partimage.
Clonezilla is an open-source suite of disk cloning, disk imaging and system deployment utilities. Clonezilla Server Edition uses multicast technologies to deploy a single image file to a group of computers on a local area network. Clonezilla was designed by Steven Shiau and developed by the NCHC Free Software Labs in Taiwan.
NimbleX is a small Slackware-based Linux distribution optimized to run from a CD, USB drive or a network environment. NimbleX has been praised for how fast it boots, as well as for its small disk footprint, which is considered surprising for a distribution using KDE as desktop environment. NimbleX was also remarked for its website that allows users to generate custom bootable images by using a web browser. It was also covered in mainstream Romanian press as the first Linux distribution put together by a Romanian.
Partclone is a partition clone and restore tool. It provides utilities to back up and restore partitions and is designed for higher compatibility of the file system library. It is developed by the NCHC Free Software Labs in Taiwan. It is the default backup application in Clonezilla, FOG, Redo Rescue and Rescuezilla which is simply a front end to partclone. It supports many file systems and has good performance, as it skips portions of the file system marked as free space.
SparkyLinux is a desktop-oriented operating system based on the Debian operating system. The project offers a ready to use operating system with various desktops to choose from. SparkyLinux is released 3-4 times per year to provide the latest versions of all applications.
The Ultimate Boot CD (UBCD) is a bootable CD-ROM containing a collection of diagnostic tools including CPU tests, memory tests, virus scanning, and other tools.
