Understanding File-level Snapshots in Windows with File History

Understanding File-level Snapshots: Windows File History

Windows File History is a built-in backup feature in the Windows operating system. It automatically saves multiple versions of files in your libraries, desktop, contacts, and favorites folders. With File History, you can easily recover files that you accidentally modified or deleted.

How File History Works

File History works by taking snapshots of your files at regular intervals. By default, it saves a new version of your files every hour. However, you can change the interval to suit your needs. File History saves these snapshots to an external drive or network location, providing an off-site backup of your files.

Configuring File History

To configure File History, follow these steps:

1. Connect an external drive to your computer.
2. Open the Control Panel and select System and Security.
3. Under Backup and Restore (Windows 7), click Turn on File History.
4. Select the drive you want to use for File History and click OK.

Restoring Files with File History

To restore files with File History, follow these steps:

1. Open the Control Panel and select System and Security.
2. Under Backup and Restore (Windows 7), click Restore my files.
3. Select the files you want to restore and click Restore.

Key Concepts

• Snapshots: A snapshot is a copy of your files at a specific point in time. File History takes snapshots of your files at regular intervals and saves them to an external drive or network location.
• Libraries: Libraries are collections of folders that are stored in a central location. File History automatically backs up files in your libraries, including your Documents, Music, Pictures, and Videos folders.
• External Drive: An external drive is a separate hard drive that you can connect to your computer. File History uses an external drive to store snapshots of your files.
• Network Location: A network location is a shared folder on a network. File History can also save snapshots of your files to a network location.
