It can create file and folder backups, as well as [[system image]]s backups, to be used for recovery in the event of [[data corruption]], [[hard disk drive failure]], or [[malware]] infection. It replaces [[NTBackup]], which has been part of Windows since [[Windows NT 3.51]]. Unlike its predecessor, it supports [[Compact disc|CDs]], [[DVD|DVDs]], and [[Blu-ray|Blu-rays discs]] as backup media.
Backup and Restore offers file and folder backup in all editions of Windows. But its full set of features are only available on high-end editions of Windows, i.e., the Professional, Business, Enterprise, and Ultimate editions.
Microsoft [[deprecated]] Backup and Restore in [[Windows 8.0]], recommending to use the [[Features new to Windows 8#File History|File History]] app for file-based backup and a third-party solution for system imaging. Despite its deprecation, however, it is part of all versions of Windows released thereafter.

== Backup types ==
Backup and Restore supports two different types of backup: File and folder backup, and system image.
===File and folder backup===
The Backup and Restore app can create backup copies of individual files and folders. These backups are saved to [[ZIP (file format)|ZIP]] files. Two methods of file backup are supported. The first, normal backup, stores everything selected for backup. The second, [[incremental backup#Incremental|incremental backup]] stores only files that are changed after a previous backup.
File backup in Windows Vista does not allow users to choose specific files, locations, or users to back up; instead, it backs up content from all users based on categories: audio tracks, compressed files, documents, email, photos, recorded television shows, videos, and additional user files. Users can only choose whether to perform a backup of a certain category.<ref name="TechRepublic">{{cite web|last=Shultz|first=Greg|date=25 April 2007|title=Back up your files with Vista's Back Up Files wizard|url=https://www.techrepublic.com/article/back-up-your-files-with-vistas-back-up-files-wizard/|access-date=9 January 2021|work=[[TechRepublic]]|publisher=[[CBS Interactive]]}}</ref> Microsoft hoped that this simplistic approach would prove appealing to users who were easily appalled by "a long tree of checkboxes."<ref name="BackupFAQ" />
File backup in Windows 7 presents two options for operation: ''Let Me Choose'', which allows users to perform backups of specific folders, [[Features new to Windows 7#Libraries|libraries]], and to create a system image; and ''Let Windows Choose'', which creates backups of all personal data in user folders and libraries, and also creates a system image.<ref name="Tip">{{cite journal|date=1 August 2016|title=Tip: Create and Use Backups Using the Backup and Restore Center|url=https://docs.microsoft.com/en-us/previous-versions/technet-magazine/ee872304(v=msdn.10)|publisher=[[Microsoft]]|access-date=9 January 2021|journal=[[TechNet Magazine]]}}</ref>
===System image===
The other method of backup, called ''Complete PC Backup'' in Windows Vista or ''system image'' in Windows 7, is a [[Block (data storage)|block]]-by-block [[disk image]] of the system, saved in a [[VHD (file format)|VHD]] file. The block-based backup is more efficient at performing subsequent [[incremental backup#Differential|differential backups]], as only the blocks that have changed need to be backed up.<ref name="BackupFAQ">{{cite web |url=http://blogs.technet.com/filecab/pages/file-backup-in-windows-vista-faq.aspx |title=File Backup in Windows Vista FAQ |date=6 November 2006 |publisher=[[Microsoft]] |work=[[Microsoft TechNet|TechNet]] Blogs (The Storage Team at Microsoft – File Cabinet Blog) |url-status=dead |archive-url=https://web.archive.org/web/20070210062512/http://blogs.technet.com/filecab/pages/file-backup-in-windows-vista-faq.aspx |archive-date=10 February 2007 |access-date=9 January 2021}}</ref><ref>[http://windows.microsoft.com/en-US/windows7/Back-up-your-programs-system-settings-and-files Back up... programs, system settings, and files (Windows 7)].</ref><ref name=":0">{{cite web |url=https://technet.microsoft.com/en-us/magazine/ee872416.aspx |title=Create and Use a Virtual Hard Disk on Windows 7 |date=August 2016 |publisher=Microsoft}}</ref> However, Backup and Restore can also only create system images of disks formatted with the [[NTFS]] [[file system]].<ref name="Tip" />

Alternatively, one could mount the VHD image as a virtual disk, allowing extraction of individual files. The mounted virtual disk has all the features of an actual volume, meaning that the [[Previous Versions]] feature of Windows 7 is available on it.

== Backup targets ==
Backups could be stored on the root of any storage device other than the one being backed up or on a [[network share]]. However, Backup and Restore does not support backing up to a subfolder of a volume.<ref name="Subfolder">{{cite web|author=Sneha|date=25 August 2009|title=Backup destination subfolder selection|url=http://social.technet.microsoft.com/Forums/en/w7itproui/thread/626b8ecf-e415-4fd8-95d7-fa02e4ad36f0|url-status=dead|archive-url=https://web.archive.org/web/20101015041703/http://social.technet.microsoft.com/Forums/en/w7itproui/thread/626b8ecf-e415-4fd8-95d7-fa02e4ad36f0|archive-date=15 October 2010|access-date=23 December 2011|work=Windows 7 IT Pro Forums ([[Microsoft TechNet|TechNet]])|publisher=[[Microsoft]]|quote=Right now, backup does not support backing up to a sub folder of a volume.

Backup and Restore is only a [[Frontend and Backend|frontend]] for interfacing with the user. The [[Frontend and Backend|backend]] component is a [[Windows service]] called Windows Backup. This service runs independent of user sessions and can perform scheduled backups even when no users have logged onto the system. Scheduled backups, by default, run every Sunday at 7 P.M.<ref name="Tip" />
During a backup, Windows uses the [[Shadow Copy|Volume Shadow Copy Service]] (VSS) to ensure that files are not changed while they are being backed up.<ref>{{cite web|title=Overview of Processing a Backup Under VSS| date=7 January 2021 |url=https://msdn.microsoft.com/en-us/library/aa384589(v=VS.85).aspx|publisher=Microsoft Developer Network (MSDN)}}</ref> VSS ensures both file system-level consistency and app-level consistency for apps registered as ''VSS writers''. In Windows Vista and Windows 7, another Windows component called [[System Restore]] also uses VSS. As such, System Restore can use shadow copies that Backup and Restore created during a full system backup.<ref name="WindowsVistaBackupTechNet">{{cite journal|last=Fok|first=Christine|date=September 2007|title=A Guide to Windows Vista Backup Technologies|url=https://technet.microsoft.com/en-us/magazine/2007.09.backup.aspx|journal=[[TechNet Magazine]]|publisher=[[Microsoft]]|access-date=19 May 2011|quote=Shadow copies created during File Backup and Complete PC Backup can also be used as restore points.}}</ref>
As mentioned above, Backup and Restore is merely a frontend. Windows ships with an alternative frontend for Windows Backup, the [[WBAdmin]] [[Command line utility|command-line utility]]. Only a member of the Administrators groups or the Backup Operators group can run WBAdmin.
== Edition comparison ==
The Home Basic edition of Windows can perform manual file backups. The Home Premium and later editions can automate file backups, create file backups on network locations, create backup schedules, and perform incremental backups of files. The Professional, Business, Enterprise, and Ultimate editions support both the system image and Shadow Copy.<ref name="WVGPRevisions">{{cite web |url=http://download.microsoft.com:80/download/8/4/f/84f00e29-10b8-4342-a102-f75100c8aa15/WVPG%20Revisions%20RTM.pdf |title=Windows Vista Product Guide — Revisions |publisher=Microsoft |archive-url=https://web.archive.org/web/20090131021942/http://download.microsoft.com/download/8/4/f/84f00e29-10b8-4342-a102-f75100c8aa15/WVPG%20Revisions%20RTM.pdf |archive-date=31 January 2009 |access-date=25 October 2019 |url-status=dead }}</ref> The user interface of Complete PC Backup in Windows Vista does not support creating a system image to a network ___location; however, the [[WBAdmin]] command can perform this operation.

==Deprecation==
With the release of [[Windows 8]], Microsoft deprecated Backup and Restore in favor the new [[File History]] feature. Microsoft cited low use as the contributing factor for its deprecation, though the company retained all of its functionality for users who relied on it; the feature was moved to a '''Windows 7 File Recovery''' Control Panel applet and all previous points of access were removed.<ref name="W7FR">{{cite web |url=https://msdn.microsoft.com/en-us/library/windows/desktop/hh848073(v=vs.85).aspx |title=Windows 7 Backup and Restore deprecated |website=[[MSDN]] |date=September 2020 |publisher=[[Microsoft]] |access-date=8 January 2021}}</ref> In Windows 8.1, all interface functionality—with the exception of system image creation, which is in a '''System Image Backup''' option in File History—were removed.<ref name="81Backup">{{cite web |url=http://blogs.technet.com/b/keithmayer/archive/2012/08/27/backup-amp-recovery-of-windows-8-windows8-itpro-tipoftheday.aspx |title=Backup and Recovery of Windows 8 & Windows 8.1 – Tip-of-the-Day |last=Mayer |first=Keith |date=17 September 2013 |publisher=[[Microsoft]] |work=[[Microsoft TechNet|TechNet]] |url-status=dead |archive-url=https://web.archive.org/web/20151207180804/http://blogs.technet.com/b/keithmayer/archive/2012/08/27/backup-amp-recovery-of-windows-8-windows8-itpro-tipoftheday.aspx |archive-date=7 December 2015}}</ref> Scheduling system image backups is not supported either.
