What should I do if a file is skipped during a backup and restore process on my Windows PC? Error code 0x8100002F appears during the process. Would you advise me?

0x8100002F backup errors are caused by several factors. We will find out more about these errors in the following sections.

What causes Windows Backup error code 0x8100002F?

In Windows Backup, the files are skipped because they can’t be found, so any changes in folder paths will cause the libraries to fail to recognize them. Since Windows backups data via user libraries, changes in folder paths won’t be recognized by the libraries. There are other reasons why a backup isn’t completed, such as corrupted system files, hard drive failure, etc.

Windows Backup can’t back up the files in the LocalLow, Contacts, and Searches folders: Another common reason for this error is that Windows Backup is forced to back up files that are not on your computer. In this case, you can either ignore the message or exclude folders from files and backups in the Backup Settings menu.

Library backup contains custom folders: This error can occur if you try to back up a library that contains custom folders located in your user profile. If this scenario applies, you can solve the problem by moving the library folder from the user profile path to a location outside the user profile path or by making the backup ignore this folder.

The process is interrupted by hard disk errors: If the disk accessed by the Windows backup utility is corrupted by bad sectors or blocks, this utility should be able to fix most of the surface problems that can cause this behavior.
