Building Win 8 Learn : Protecting User Files With File History

[Spartan]

[b] What is File History?[/b]

[b]File History[/b] is a backup application that continuously protects your personal files stored in Libraries, Desktop, Favorites, and Contacts folders. It periodically (by default every hour) scans the file system for changes and copies changed files to another location. Every time any of your personal files has changed, its copy will be stored on a dedicated, external storage device selected by you. Over time, File History builds a complete history of changes made to any personal file.
It’s a feature introduced in Windows 8 that offers a new way to protect files for consumers. It supersedes the existing Windows Backup and Restore features of Windows 7.
What is unique about this approach compared to a more traditional backup and restore?
Regretfully, backup is not a very popular application. Our telemetry shows that less than 5% of consumer PCs use Windows Backup and even adding up all the third party tools in use, it is clear nowhere near half of consumer PCs are backed up. This leaves user’s personal data and digital memories quite vulnerable as any accident can lead to data loss. In Windows 8 Microsoft is actively trying to accomplish the following:[list=1]
[*]Make data protection so easy that any Windows user can turn it on and feel confident that their personal files are protected.
[*]Eliminate the complexity of setting up and using backup.
[*]Turn backup into an automatic, silent service that does the hard work of protecting user files in the background without any user interaction.
[*]Offer a very simple, engaging restore experience that makes finding, previewing and restoring versions of personal files much easier.
[/list]
While designing File History we used learnings from the past and added requirements to address the changing needs of PC users.[list]
[*]PC users are more mobile than ever. To address that, we optimized File History to better support laptops that constantly transition through power states or are being connected and disconnected from networks and devices.
[*]PC users create more data and are more dependent on it than ever before. So we do not only protect what’s currently on the system drive but also any work they have done and data they have created in the past.
[/list]
When a specific point in time (PiT) version of a file or even an entire folder is needed, you can quickly find it and restore it. The restore application was designed to offer engaging experience optimized for browsing, searching, previewing and restoring files.

[b] Setting it up[/b]

Before you start using File History to back up your files, you'll need to set up a drive to save files to. We recommend that you use an external drive or network location to help protect your files against a crash or other PC problem.
File History only saves copies of files that are in your libraries, contacts, favorites, and on your desktop. If you have folders elsewhere that you want backed up, you can add them to one of your existing libraries or create a new library.
To set up File History[list=1]
[*]Open [b]File History[/b] control panel applet.
[*]Connect an external drive, refresh the page, and then tap or click [b]Turn on[/b]

[/list]


You can also set up a drive in AutoPlay by connecting the drive to your PC, tapping or clicking the notification that appears…… and then tapping or clicking [b]Configure this drive for backup[/b].

That’s it. From that moment, every hour, File History will check your libraries, desktop, favorites and contacts for any changes. If it finds changed files, it will automatically copy them to the File History drive.

[b] Restoring files[/b]

When something bad happens and one or more personal files are lost, the restore application makes it very easy to:[list]
[*]Browse personal libraries, folders and files in a way very similar to Windows Explorer.
[*]Search for specific versions using keywords, file names and date ranges.
[*]Preview versions of a selected file.
[*]Restore a file or a selection of files with one tap or a click of a mouse.
[/list]
We designed the restore application for wide screen displays and to offer a unique, engaging and convenient way of finding a specific version of a file by looking at its preview.
With other backup applications you would have to select a backup set that was created on a specific date. Then you would have to browse to find a specific folder, and then find the one file you need. However at this point it is impossible to open the file or preview its content in order to determine if it is the right one. You would have to restore the file. If it is not the right version, you’d have to start over.
With File History, the search starts right in Windows Explorer. You can browse to a specific location and click or tap on the History button in the explorer ribbon in order to see all versions of the selected library, folder or an individual file.
For example, when you select a Pictures library and click or tap on the History button…… you will see the entire history of this library.

When you click on a specific file, you can see the entire history of the selected picture.

[b] Optimized for performance[/b]

In the past, most backup applications used brute force method of checking for changes in directories or files by scanning the entire volume. This approach could significantly affect the system performance and requires an extended period of time to complete. File History, on the other hand, takes advantage of the NTFS change journal. The NTFS change journal records any changes made to any files stored on an NTFS volume. Instead of scanning the volume, which involves opening and reading directories, File History opens the NTFS change journal and quickly scans it for any changes. Based on this information it creates a list of files that have changed and need to be copied. The process is very quick and efficient.

File History was designed to be easily interrupted and to quickly resume. This way, File History can resume its operation, without the need to start over when a system goes into sleep mode, a user logs off, the system gets too busy and needs more CPU cycles to complete foreground operations, or the network connection is lost or saturated.
File History was designed to work well on any PC including small form factor PCs with limited resources and tablets. It uses system resources in a way to minimize the impact on system performance, battery life and overall experience.
