You try to back up a QuickBooks company file that is open but cannot, and the status shows Backup Failed.


  • If the company file (QBW) and Intuit Data Protect do not reside on the same computer, the company file may need to be closed in QuickBooks so that the backup will complete successfully.
  • If you are backing up a file located on a network resource, be sure you are using a mapped drive and not the UNC path (\\<pathname>). 

Why this is happening

Typically, Intuit Data Protect (IDP) will backup files that are open. However, there are times when this is not the case. Below are instances where IDP is unable to back up open files:

  • The QuickBooks company file is open via a mapped network drive during the time backup occurs
  • IBuEngHost.exe is not running as the user SYSTEM, but instead running as the local user
  • Your Windows File system is not NTFS
  • Volume Shadow Copy Service (VSS) in Windows is not started
