Ghost (disk utility)

GHOST (an acronym for general hardware-oriented system transfer), now called Symantec™ GHOST Solution Suite (GSS) for enterprise, is a disk cloning and backup tool originally developed by Murray Haszard in 1995 for Binary Research. The technology was bought in 1998 by Symantec.

The backup and recovery feature was replaced by Symantec System Recovery (SSR).

Broadcom bought Symantec's Enterprise Security business in 2019.

GHOST is marketed as an OS (Operating System) deployment solution. Its capture and deployment environment requires booting to a Windows PE environment. This can be accomplished by creating an ISO (to burn to a DVD) or a USB bootable disk, installed to a client as an automation folder or delivered by a PXE server. This provides an environment to perform offline system recovery or image creation. GHOST can mount a backup volume to recover individual files.

GHOST can copy the contents of one volume to another or copy a volume's contents to a virtual disk in VMDK or VHD format.

Initially, GHOST supported only the FAT file system, but could only copy (not resize) other file systems by performing a sector-by-sector transfer. GHOST added support for NTFS later in 1996, and also provided a program, Ghostwalker, to change the Security ID (SID) that made Windows NT systems distinguishable from each other. Ghostwalker is capable of modifying the name of the Windows NT computer from its own interface. GHOST added support for the EXT2 file system in 1999 and for EXT3 subsequently. Support for EXT4 was added in September 2017 (Enterprise only).

Binary Research developed GHOST in Auckland, New Zealand. After the Symantec acquisition, a few functions (such as translation into other languages) were moved elsewhere, but the main development remained in Auckland until October 2009 at which time much was moved to India.^{[citation needed]}

Technologies developed by 20/20 Software were integrated into GHOST after their acquisition by Symantec in April 2000.
