Norton GoBack (previously WildFile GoBack, Adaptec GoBack, and Roxio GoBack) is a disk utility for Microsoft Windows that can record up to 8 GB of disk changes. When the filesystem is idle for a few seconds, it marks these as "safe points". The product allows the disk drive to be restored to any point within the available history. It also allows older versions of files to be restored, and previous versions of the whole disk to be browsed. Depending on disk activity, the typical history might cover a few hours to a few days.
GoBack replaces the master boot record, and also replaces the partition table with a single partition. This allows a hard drive to be changed back, even in the event that the operating system is unable to boot, while also protecting the filesystem from alteration so that the revert information remains correct.
GoBack is compatible with hardware RAID drives.
Due to the changes made to the partition table, this can cause problems when dual booting other operating systems on the same hard disk. It is possible to retain dual-boot compatibility, but can involve saving the partition table before enabling GoBack, and after enabling GoBack, re-writing the partition table back to the disk (after booting from a different device, such as a Live CD).
It may also be necessary to disable GoBack prior to using certain low level disk utilities, such as formatting software. Such low level utilities which do not first check for the presence of GoBack can (in combination with GoBack) cause data to become corrupted. Another example of an incompatible program is the Windows version of True Image For Windows. GoBack is also incompatible with products such as Drive Vaccine PC Restore and RollBack Rx - as these products require access to the master boot record.
Disk partitioning or disk slicing is the creation of one or more regions on secondary storage, so that each region can be managed separately. These regions are called partitions. It is typically the first step of preparing a newly installed disk, before any file system is created. The disk stores the information about the partitions' locations and sizes in an area known as the partition table that the operating system reads before any other part of the disk. Each partition then appears to the operating system as a distinct "logical" disk that uses part of the actual disk. System administrators use a program called a partition editor to create, resize, delete, and manipulate the partitions. Partitioning allows the use of different filesystems to be installed for different kinds of files. Separating user data from system data can prevent the system partition from becoming full and rendering the system unusable. Partitioning can also make backing up easier. A disadvantage is that it can be difficult to properly size partitions, resulting in having one partition with too much free space and another nearly totally allocated.
IBM PC DOS, an acronym for IBM Personal Computer Disk Operating System, is a discontinued disk operating system for the IBM Personal Computer, its successors, and IBM PC compatibles. It was manufactured and sold by IBM from the early 1980s into the 2000s. Developed by Microsoft, it was also sold by that company as MS-DOS. Both operating systems were identical or almost identical until 1993, when IBM began selling PC DOS 6.1 with new features. The collective shorthand for PC DOS and MS-DOS was DOS, which is also the generic term for disk operating system, and is shared with dozens of disk operating systems called DOS.
Peter Norton is an American programmer, software publisher, author, and philanthropist. He is best known for the computer programs and books that bear his name and portrait. Norton sold his software business to Symantec Corporation in 1990.
In the maintenance of file systems, defragmentation is a process that reduces the degree of fragmentation. It does this by physically organizing the contents of the mass storage device used to store files into the smallest number of contiguous regions. It also attempts to create larger regions of free space using compaction to impede the return of fragmentation. Some defragmentation utilities try to keep smaller files within a single directory together, as they are often accessed in sequence.
PartitionMagic is a utility software program for hard disk drive partitioning originally made by PowerQuest, but subsequently owned by Symantec. As of December 8, 2009, the Symantec website stated that they no longer offer PartitionMagic.
Disk cloning is the process of duplicating all data on a digital storage drive, such as a hard disk or solid state drive, using hardware or software techniques. Unlike file copying, disk cloning also duplicates the filesystems, partitions, drive meta data and slack space on the drive. Common reasons for cloning a drive include; data backup and recovery; duplicating a computer's configuration for mass deployment and for preserving data for digital forensics purposes. Drive cloning can be used in conjunction with drive imaging where the cloned data is saved to one or more files on another drive rather than copied directly to another drive.
Ghost is a disk cloning and backup tool originally developed by Murray Haszard in 1995 for Binary Research. The technology was acquired in 1998 by Symantec.
Norton AntiVirus is an anti-virus or anti-malware software product founded by Peter Norton, developed and distributed by Symantec since 1990 as part of its Norton family of computer security products. It uses signatures and heuristics to identify viruses. Other features included in it are e-mail spam filtering and phishing protection.
Norton Utilities is a utility software suite designed to help analyze, configure, optimize and maintain a computer. The latest version of the original series of Norton Utilities is Norton Utilities 16 for Windows XP/Vista/7/8 was released 26 October 2012.
Norton Internet Security, developed by Symantec Corporation, is a discontinued computer program that provides malware protection and removal during a subscription period. It uses signatures and heuristics to identify viruses. Other features include a personal firewall, email spam filtering, and phishing protection. With the release of the 2015 line in summer 2014, Symantec officially retired Norton Internet Security after 14 years as the chief Norton product. It was superseded by Norton Security, a rechristened adaptation of the Norton 360 security suite.
Microsoft Anti-Virus (MSAV) is an antivirus program introduced by Microsoft for its MS-DOS operating system. The program first appeared in MS-DOS version 6.0 (1993) and last appeared in MS-DOS 6.22. The first version of the antivirus program was basic, had no inbuilt update facility and could scan for 1,234 different viruses. Microsoft Anti-Virus for Windows (MWAV), included as part of the package, was a front end that allowed MSAV to run properly on Windows 3.1x.
A disk compression software utility increases the amount of information that can be stored on a hard disk drive of given size. Unlike a file compression utility, which compresses only specified files—and which requires the user to designate the files to be compressed—an on-the-fly disk compression utility works automatically through resident software without the user needing to be aware of its existence. On-the-fly disk compression is therefore also known as transparent, real-time or online disk compression.
Norton SystemWorks is a discontinued utility software suite by Symantec Corp. It integrates three of Symantec's most popular products – Norton Utilities, Norton CrashGuard and Norton AntiVirus – into one program designed to simplify solving common PC issues. Backup software was added later to high-end editions. SystemWorks was innovative in that it combined several applications into an all-in-one software for managing computer health, thus saving significant costs and time often spent on using different unrelated programs. SystemWorks, which was introduced in 1998 has since inspired a host of competitors such as iolo System Mechanic, McAfee Nuts And Bolts, Badosoft First Aid and many others.

Wubi is a free software Ubuntu installer, that was the official Windows-based software, from 2008 until 2013, to install Ubuntu from within Windows, to a single file within an existing Windows partition.
Disk cloning software facilitates a disk cloning operation by using software techniques to copy data from a source to a destination drive or to a disk image..
Clonezilla is a suite of open source drive cloning, drive imaging and system deployment utilities used to simplify deployment and maintenance of a group of computers. 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.
DOS is a family of disk-based operating systems for IBM PC compatible computers. The DOS family primarily consists of Microsoft's MS-DOS and a rebranded version, IBM PC DOS, both of which were introduced in 1981. Later compatible systems from other manufacturers include DR-DOS (1988), ROM-DOS (1989), PTS-DOS (1993), and FreeDOS (1998). MS-DOS dominated the IBM PC compatible market between 1981 and 1995.
A master boot record (MBR) is a special type of boot sector at the very beginning of partitioned computer mass storage devices like fixed disks or removable drives intended for use with IBM PC-compatible systems and beyond. The concept of MBRs was publicly introduced in 1983 with PC DOS 2.0.
Norton 360 was an "all-in-one" security suite for the consumer market developed by Symantec. Originally released in 2006, it was discontinued in 2014; its features were carried over to its successor, Norton Security.
