You must have used the Windows XP System Restore function, but it can only return the original machine files, if there is a shared folder on the network, users accidentally delete or overwrite the folder, then Windows XP System Restore power to the secondary shared files can be powerless. This problem is solved with the introduction of the Windows Server 2003 operating system. This is the Volume Shadow Copy Service for Windows Server 2003. It can "back up" a shared folder on a network server, "Backup is called a shadow copy of a shared folder, and through a shadow copy of a shared folder, you can view the shared files and folders that existed in the past, using shadow copies to recover files that were accidentally deleted, or to recover files that were accidentally overwritten. Note, however, that shadow copies are not substitutes for regular backups, and that shadow copies do not exist if the disk that stores the data is corrupted. Note: When we enable shadow copies, we can set a storage limit for shadow copies. When the disk space stored by the shadow copy reaches this custom limit, the newly generated shadow copy will overwrite the oldest version of the shadow copy, and the overwritten old version of the shadow copy cannot be restored.

If we want to enable shadow copies under the server's C disk, we right-click on the C disk, click "Properties" in the menu that appears, click the "Shadow copy" tab in the Properties window that appears, select a volume, we select C, and then click the "Enable" button, as shown in Figure 1:
Select "Enable" in the pop-up window, and to this, pop-up window, as shown in Figure 2:
Click: "Yes" to confirm, this time the shadow copy is enabled. After the shadow copy feature is enabled, the system creates the first shadow copy for us, as shown in Figure 3:
