Windows provides the following backup tools:

• File backup: Windows Backup allows you to make copies of data files. You can let Windows choose what to back up or you can select the individual folders, libraries, and drives that you want to back up. By default, your backups are created on a regular schedule. You can change the schedule and you can manually create a backup at any time. Once you set up Windows Backup, Windows keeps track of the files and folders that are new or modified and adds them to your backup. To set up file backup, see the following backup steps

• System image backup: Windows Backup provides you with the ability to create a system image, which is an exact image of a drive. A system image includes Windows and your system settings, programs, and files. You can use a system image to restore the contents of your computer if your hard drive or computer ever stops working. When you restore your computer from a system image, it is a complete restoration; you can’t choose individual items to restore, and all of your current programs, system settings, and files are replaced. Although this type of backup includes your personal files, we recommend that you back up your files regularly using Windows Backup so that you can restore individual files and folders as needed. When you set up scheduled file backup, you can choose whether you want to include a system image. This system image only includes the drives required for Windows to run. You can manually create a system image if you want to include additional data drives. See an automated system image backup example

• Previous versions: Previous versions are copies of files and folders that Windows automatically saves as part of system protection. You can use previous versions to restore files or folders that you accidentally modified or deleted, or that were damaged. Depending on the type of file or folder, you can open, save to a different location, or restore a previous version. Previous versions can be helpful, but should not be considered a backup because the files get replaced by new versions and will not be available if the drive were to fail.

Important Note - a drive needs to have system protection enabled in order to be included in a restore point and in order to have the previous copies of files and folders functionality!

You launch the System Protection box from the control panel: (Click Start\Control Panel)

Custom Search

1. In the Control Panel Click System and Security
2. In the System and Security window click System
3. In the System window click System Protection – now you have the System Properties window open with the System Protection tab selected

  4.   Select the drive you want to set and click Configure
  5.   After you make the required settings click OK

Required settings:

Restore system settings and previous versions of files

This is the default setting for the system drive or volume. Do not change this default setting, since restore points here hold system information and user files that are present in the user profile. Disk Space Usage depends on how much space is used for user files. If your files reside in this drive or volume then 20% to 40% should be ok. If the drive is set to hold just system files then 10% should be enough.

Only restore previous versions of files

You normally use this option on drives or volumes that contain user files only such as, a second disk drive for data storage. A value of 40% of Disk space usage would give you a large number of previous versions of your files.

Turn off system protection

This would be the setting for external backup drives or USB disks that hold backup file sets. The main problem with USB drives is that they are normally formatted using the FAT file system. Remember that System Protection works only with NTFS formatted drives!

Last but crucial point is that old previous versions of files that were overwritten due to a low Disk Space Usage setting will not become available by increasing the Disk Space Usage percentage! Then, you need to revert to a restore process from a backup set!

To restore a file or folder you simply right-click the file or folder (in windows explorer) and select the Restore previous versions option.
If the Restore previous versions is not available then your file structure must have been changed. Also, note that the restore operation is not reversible!

From the Restore previous versions window select the date of the desired restore point. If no previous dates are available, the selected file or folder has not been modified.

You have three options. You can Open the file (Open button) and view its contents and save it to an alternate location, you can Copy the file (Copy button) to an alternate location or you can just restore the file by clicking the Restore button.

Remember, that if you cannot find previous copies of files, then you have system protection disabled for that drive. Also, shadow copies are unavailble for Offline files and system files that are used by the Windows 7.
