Fix: Windows backup or restore fails with errors 0x80070001, 0x81000037, 0x80070003
When you try to back up or to restore files or folders by using Windows Backup and Restore feature, the process fails and you receive any of the following errors:
0x80070001 (Invalid Function)
0x80070003
0x81000037: Windows Backup failed while trying to read from the shadow copy on one of the volumes being backed up
Additionally, you may be unable to browse to the files and folders that you want to restore in the File Restore Wizard.
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.
If this happens, you may want to see KB973455 for ways on how to resolve these errors.
