Windows 7 Backup fails if file path length exceeds 260 characters

If your backup operation fails in Windows 7 or Windows Server 2008 R2, if the file path length is longer than 260 characters, then this article may interest you.

Windows Backup fails if file path length exceeds 260 characters

Consider the following scenario:

  • You customize a backup operation to back up some files on a computer that is running Windows Server 2008 R2 or Windows 7.
  • You select some files that you want to include in the backup operation. The path length of one selected file is longer than 260 characters.

In this scenario, the backup operation fails after the backup operation is started.

This issue occurs because the Windows Block Level Backup Engine service (Wbengine.exe) handles file paths that are longer than 260 characters incorrectly.
