Backup and Restore of Data Deduplication-Enabled Volumes (Windows) The data deduplication feature enables backup applications to perform optimized backup and restore of volumes that are enabled for data deduplication.
There are also situations where it is preferable to perform nonoptimized backup and restore. In addition to reading this documentation, you should also study the DedupBackupRestore sample, which is useful for understanding multiple restore scenarios. Optimized Backup In optimized backup, the backup application does the following: Uses a shadow copy of the optimized volume.Specifies the FILE_FLAG_OPEN_REPARSE_POINT flag when opening the data deduplication-optimized files.Copies the optimized files (reparse points) and chunk store container files as-is from the shadow copy to the backup store. In many cases, such as a full volume backup (either block-level or file-level), performing an optimized backup will result in a smaller, faster backup than an unoptimized backup.

Data loss occurs when the Winsock "recv" function returns 0 bytes if both the client-side and the server-side applications run on the same computer that is running Windows Server 2003. Consider the following scenario: You make a Winsock connection on a computer that is running Windows Server 2003.
Both the client-side and the server-side applications run on this computer.You call the recv function to receive data.In this scenario, the recv function returns 0 bytes randomly. This returned value of 0 bytes causes data loss. However, if you immediately call the recv function again, the expected data is received successfully. The TCP/IP protocol driver (Tcpip.sys) triggers a disconnect event randomly while the driver receives a receive request.
Therefore, the data transfer process is interrupted, and the issue mentioned in the "Symptoms" section occurs. Hotfix information A supported hotfix is available from Microsoft. If the hotfix is available for download, there is a "Hotfix download available" section at the top of this Knowledge Base article.
