* pdumpfs, authored by Satoru Takabayashi, is a simple daily backup system similar to Plan 9's /n/dump, implemented in [[Ruby (programming language)|Ruby]]. It functions as a snapshotting tool, which makes it possible to copy a whole directory to another ___location by using hardlinks. Used regularly, this can produce an effect similar to versioning.<ref>[https://archive.is/20120701101406/http://0xcc.net/pdumpfs/index.html.en pDumpFS Homepage]</ref>
*Microsoft Windows
** [[Shadow Copy]] - is a feature introduced by Microsoft with Windows Server 2003, 2008, 2012 as well as Windows 7, 8, and 10. [[Shadow Copy]] allows for taking manual or automatic backup copies or snapshots of a file or folder on a specific volume at a specific point in time.
** RollBack Rx - Allows snapshots of disk partitions to be taken. Each snapshot contains only the differences between previous snapshots, and take only seconds to create. Can be reliably used to keep a Windows OS stable and/or protected from malware.
** [[GoBack]] (discontinued) - The GoBack software for Windows from [[NortonLifeLock|Symantec]] enables reversion of files, directories or disks to previous states. It can record a maximum of 8GB in changes, and temporarily stops recording each change in the event of high [[I/O]] activity.
