Back up QuickBooks files with the Code42 agent

The following instructions suggest backing up the QuickBooks company file or backup file. See the QuickBooks community for a list of QuickBooks files for Windows and Mac that you may also want to back up.


  1. Go to Manage Files in the Code42 agent. 
  2. Add your QuickBooks company file (.qb2017) to your file selection. The default location of this file is C:\Users\Public\Public Documents\Intuit\QuickBooks\Company Files.
    On Mac, add your QuickBooks .dmb file to your file selection.


  1. Schedule automated backups in QuickBooks (creating a .qbb file).
  2. Go to Manage Files in the Code42 agent. 
  3. Add the .qbb file to your Code42 agent file selection.

VSS and QuickBooks

The Code42 agent can back up open files, like the QuickBooks' company data file (.qbw), by default. However, in Windows, the Code42 agent relies on VSS (Volume Shadow service) to back up these open files. While VSS works great for many applications, the file formats used by certain programs, such as QuickBooks, can create limitations that make VSS backups less than ideal.

Although VSS can make a backup copy of your open .qbw file, the backup won't be as robust as a QuickBooks Backup file (.qbb). When you create a .qbb file with QuickBooks, the application verifies the integrity of the .qbw file, and also backs up your templates, letters, and logos. Additionally, it backs up information from Statement Writer, CashFlow Projector, Business Planner, and Loan Manager.
