Guide on How to Fix Windows Backup Error 0x8100002F
Getting an error 0x8100002F while trying to backup my Windows
Hello! I was trying to back up my files and system using Backup and Restore but they give me this message: “The backup completed but some files were skipped.”. Please help me fix this. Thank you.
Losing files when you really need them sounds so stressful and alarming. Imagine not being able to present your business plan to your clients? Or not being able to submit your school project online just because you lost your files?
That’s why it is important that you backup your files and even your system! Good thing Windows has Backup and Restore. With Backup and Restore, your files, folders, and PC system will have backups that you can use for recovery in case your computer has a malware infection, your files got broken, or your computer hard disk had failed.
But the thing here is, some users are not able to successfully back up their files using Backup and Restore because of the error 0x8100002F.
Before we dive into the guide – we always highly advise using a reliable Virtual Private Network (we recommend NordVPN -> see the best deal here). This is in order to encrypt and protect your network as well as secure your PC from malicious websites.
What is Error 0x8100002F?
Error 0x8100002F is a backup error that usually happens when the backup is completed yet skipped some files. Once your computer detects this error, it will display the message “The backup completed but some files were skipped.”
We can say that the cause of this error is that Windows cannot find specific files. Once there is a change on the folder path, user libraries will not recognize the files leading to the error. It is because Windows backs up the data through user libraries. Moreover, corrupted system files, hard disk failure, and more can also cause the error.
With that being said, we recommend using iolo System Mechanic, to scan hardware issues and restore faulty or missing DLL files. And to help you fix the issue, below are the methods you can use to solve Error 0x8100002F.
