This article describes how to work around various issues that occur when you try to back up or to restore files or folders by using Windows Backup and Restore. When this Windows Backup and Restore issue occurs, you receive the following errors:
Additionally, you may be unable to browse to the files and folders that you want to restore in the File Restore Wizard.
For detailed information, see the “Symptoms,” “Cause,” “Workaround,” and “More information” sections of this article.
Issues that occur when you try to back up files
You receive the following error code when you try to back up files or folders by using Windows Backup and Restore:
0x80070001 (Invalid Function)
This issue occurs when you try to back up a specific library or when you accept the default settings in Windows Backup and Restore.
These issues occur because the folders or libraries that you are trying to back up or restore include a reparse point. Reparse points resemble Windows shortcuts or to Unix symbolic links. A reparse point may be used to point to a file that is temporarily relocated on a different drive. For example, a reparse point would allow a folder such as C:\DVD to point to Drive E, the actual DVD drive.
Cause of issues that occur when you try to back up files
This issue occurs if the reparse point points to a volume that uses the FAT file system.
Work around issues that occur when you try to back up files
Issue 1 and Issue 2
To work around these issues, remove the reparse point from the library, and then run the backup wizard again. To back up content for this reparse point (in this case, the FAT volume or the mounted volume), select the absolute path of this location in the Windows Backup configuration user interface.
To locate reparse point folder or its subfolder, follow these steps:
Click Start button, type CMD in the Search program and files box and then press Enter.
In the Command Prompt window, type DIR /AL /S and then press Enter. The list of JUNCTION (one type of reparse point) list is displayed.
Note You see several entries that say "junction" and the location that the entries point to (“junction point” is another name for “reparse point”). When a program tries to write to a directory that is really a reparse point, those files are sent (completely blindly to that program) to the other directory instead.
To delete mounted volume reparse point, follow these steps:
Locate the reparse point you found, right click the reparse point icon and click Properties.
In the General tab, confirm the folder Type is Mounted Volume and then delete this folder.
Work around issues that occur when you try to restore files
To work around this problemissue, use the Search functionality in the File Restore Wizard to locate the files. To do this, follow these steps:
Enter the keywords in the Search for box, and then click Search.
Click to select the files that you want to restore from the list, and then click OK.
To work around this issue, re-create the missing directory. To do this, follow these steps:
If the reparse point is deleted, you receive the following example error message:
Follow the path that is pointed out in the error and create the corresponding folder. In this example, you create the folder MyFolder under Drive C.
Try the restore operation again.
Additionally, click to clear the Restore the files to their original subfolders check box when you run the File Restore Wizard.
By design, Windows Backup does not traverse reparse points on a computer. However, if a reparse point is directly added to a Windows 7 Library, or if any of the child nodes of a reparse point is directly added to a Windows 7 Library, Windows Backup traverses these locations. This could cause several issues during the backup process.
Note If the reparse point is added to a folder that is already part of a Windows 7 Library, Windows Backup skips the reparse point, and no problem occurs.
