File history gives you advanced backup features without requiring admin privileges.
Backup and restore are fairly common procedures. However, most backup applications, including Windows Backup and Restore that shipped with Windows 7, require administrator privileges to set up and use. This means most of your users will have to ask you to set it up every time they need to restore a file, or to grant them administrative privileges.
This isn’t the case with File History. File History gives each user full control of backup functions. Now the user can decide if and when to turn on File History and which external drive to use. In fact, the user can select a different location to store his file history. And he doesn’t have to ask for your help to restore a file.
A user can use advanced File History features to control many operational aspects, such as:
You can access advanced settings, such as Exclude, from the File History control panel applet. To exclude a folder, select Exclude folders. Next, click on the Add button, browse to the folder you want to exclude and select it. Files in this folder won’t be backed up starting with the next backup cycle. To start backing it up again, simply remove the folder from the list. There are other advanced settings available on the Advanced Settings page.
File History also supports new storage features introduced in Windows 8. If you have lots of data to back up, you can use Storage Spaces to create a resilient storage pool using off-the-shelf USB drives. When the pool fills up, you can easily add more drives and extra storage capacity.
If you use BitLocker to protect the content of your personal files, you can also use File History as it seamlessly supports BitLocker on both source and destination drives. File History was designed for consumers, but could also be used by enterprise customers.
In some cases, File History might conflict with enterprise policies (such as a retention policy). To prevent such conflicts, there’s a Group Policy that lets you turn off File History on managed client PCs. You’ll find the File History policy setting in the Group Policy Object Editor under Computer Configuration | Administrative Templates | Windows Components | File History.
File History is part of Windows 7, so you don’t need to install any additional software. However, File History has to be turned on, which typically requires only one click. To start protecting your libraries, simply attach an external drive or select a network location. File History will store versions of your files on this device.
File History automatically selects an external drive if there’s one available. If there’s more than one external drive, it will select the one with the most free storage capacity.
File History wakes up once an hour and looks for personal files that have changed. Versions of all files that have changed are replicated to a dedicated storage device. This approach eliminates the need to set up a schedule and leave a computer idle for an extended period of time. One hour frequency offers a good balance between the level of protection and amount of storage space consumed by file versions. Enthusiasts can change the frequency from 10 min to 1 day in order to increase the level of protection or reduce storage consumption.
File History runs silently in the background. It doesn’t require any ongoing maintenance. The only time it will ask you to intervene is when the external drive is full. At this point, you’ll have to either replace the drive with a bigger one or change a setting that tells File History how long to save file versions. By default, we keep versions of user personal files forever, but if storage is an issue, it can be reduced to a period of time that best suits your needs.
File History is also integrated with HomeGroup to make it easier for you to set up backup for all your home network members. Here’s how it works:
File History doesn’t back up your files to the cloud. While the cloud is great for storing files you’d like to access on the go or for sharing files with others, backing up terabytes of data to the cloud requires a specialized service.
Many cloud services today support local synchronization, where the data in the cloud is mirrored in your local file system. Sync solutions by their very nature copy changes immediately to all locations, which means accidental deletes or inadvertent changes or corruption to files will also be synchronized The best way to address this problem is to couple your sync service with a point-in-time backup solution such as File History.
File History takes advantage of your apps, files, PCs and devices being able to integrate with Skydrive. If your SkyDrive is synced to your file system, File History will automatically start protecting the files stored in your local SkyDrive folder. This is a great example of local backup plus reliable anytime, anywhere access. You can access your SkyDrive files through your PC, your phone or the Web. You’ll know File History is providing fast local backup and instantaneous access to all versions of those files.
Usually a full-system backup protects your PC against complete system loss, such as when a PC is stolen or lost or the internal hard drive stops working. Research shows only a small number of users are concerned about losing the OS, apps or settings. They are by far more concerned about losing their personal files. For this reason, File History was designed specifically to protect personal files.
File History doesn’t offer the ability to do a full-system backup, but it does offer a good compromise. Together with other features introduced in Windows 8 it provides protection against such disasters. If you want to prepare for a disaster, Microsoft recommends the following strategy:
When your PC is replaced or needs to be reinstalled:
It may require more steps than a file or image restore, but it has some clear benefits:
Those who need a full-system backup can still use Windows Backup to create a system image.
File History requires the Windows 8 client OS and an external storage device with enough storage capacity to store a copy of all user libraries, such as a USB drive, network-attached storage device or share on another PC in the home network.
File History silently protects all your important files stored in Libraries, Desktop, Favorites and Contacts. Once turned on, it requires no effort at all to protect your data. When you lose a file or just need to find an original version of a picture or a specific version of a resume, all versions of your files are available. With the File History restore application, you can find it quickly and effortlessly.
