How to fix Windows backup error 0x80070001?


Issue: How to fix Windows backup error 0x80070001?

Hello. I have a problem with my automatic backup. Since it is set to occur automatically, I receive an 0x80070001 error each time it is triggered. I am not sure how to resolve this. Any ideas? Thanks in advance.

Solved Answer

There are many reasons why data on a hard drive or solid-state drive could be lost – physical damage, hardware or software failures, theft, malware[1] infection, and more. This is why backups are extremely important for everyone who has valuable documents, pictures, databases, or other files located on their computer for various purposes.

There are plenty of choices when it comes to how backups are implemented and maintained. Automatic backups can be especially useful, as they do not require constant efforts of redoing them every now and again. Copies of data can also be stored on physical devices that are not connected to the computer directly, it includes USB thumb drives, external HDDs, NAS[2] devices, and much more.

Most people resort to automatic backups, and Windows offers a few options, even though they are pretty limited. File History is one of the built-in features that save files in Favorites, Contacts, and other folders. During one of the backup attempts, some users might experience a 0x80070001 backup error, which prevents them from successfully creating copies of their files, leaving them out of date.

Likewise, users also reported receiving the error when trying to restore Windows to its previous state using an automated backup system. This feature is useful when something goes wrong and people can restore the system into a state it used to be before the problem existed. With 0x80070001 error, users can no longer achieve that.

There is plenty of similar backup errors we talked about previously (0x81000036, 0x80070003, or 0x81000037), and each of them has its own reasons for occurring. In this case, 0x80070001 called for the “Invalid function”, which means that the reparse point points to a volume that uses the FAT file system.[3]

To fix this error, you have to access the elevated Command Prompt and perform a set of commands as we explain in detail below.
