MORE INFORMATION

Troubleshooting Microsoft Backup for Windows and Microsoft Backup

  1. Microsoft does not recommend or support running the MS-DOS-based version of Microsoft Backup (MSBACKUP.EXE) with Windows. If you choose to do this, you should create a program information file (PIF) with the following settings for Microsoft Backup:
           Display Usage: Full Screen
           Execution:  Exclusive
    					
  2. Your CONFIG.SYS file should include the following settings (the values shown are minimums):
           FILES=30
           BUFFERS=30
           STACKS=9,256
    					
  3. The DMABufferSize= line should be set to at least 32 in the [386Enh] section of the SYSTEM.INI file. In some situations, the DMA buffer size needs to be set to 40 (either in the SYSTEM.INI file, or using EMM386.EXE, or both).
  4. If you are using MSBACKUP.EXE in Windows or the Windows version of Microsoft Backup (MWBACKUP.EXE), you should place the following line in your SYSTEM.INI file if Setup did not install it:
          device=c:\dos\vfintd.386
    						
    If you omit this line, Backup displays the following error message:
    Microsoft Backup is not properly installed on this system.

    Please reinstall Microsoft Backup, or make the following changes to your SYSTEM.INI file:

    [386Enh]
    DEVICE=[ms-dos path]VFINTD.386
