Explanation:
If you enable Shadow Copies of Shared Folders on a volume using the default values, a task will be scheduled to create shadow copies at 7:00 A.M of next business day. The default storage area will be on the same volume, and its size will be 10 percent of the available space. You can only enable Shadow Copies of Shared Folders on a per-volume basis-that is, you cannot select specific shared folders and files on a volume to be copied or not copied.
To enable and configure Shadow Copies of Shared Folders:
Click Start, point to Administrative Tools, and then click Computer Management.

In the console tree, right-click Shared Folders, click All Tasks, and then click Configure Shadow

Copies.
In Select a volume, click the volume that you want to enable Shadow Copies of Shared Folders for, and

then click Enable.
You will see an alert that Windows will create a shadow copy now with the current settings and that the

settings might not be appropriate for servers with high I/O loads. Click Yes if you want to continue or No if you want to select a different volume or settings.
To make changes to the default schedule and storage area, click Settings.

Shadow copies - a feature that provides point-in-time copies of files stored on file shares on file servers.
Shadow Copies of Shared Folders allows users to view and access shadow copies, which are shared files and folders as they existed at different points of time in the past. By accessing previous versions of files and folders, users can compare versions of a file while working and recover files that were accidentally deleted or overwritten.
