SYMPTOMS

Microsoft Backup (MSBACKUP) returns following error message:

INTERNAL ERROR Open failure: C:\<path>\MSBACKUP.LOG

CAUSE

The error message may be the result of an incorrect environment setting. If the MSDOSDATA variable is set to point to an invalid subdirectory, MSBACKUP may display the above message. (The only available option is Exit Program.)

RESOLUTION

Make sure that the correct syntax is used to set the MSDOSDATA variable in the AUTOEXEC.BAT file and that a valid directory is selected. The syntax should be as follows

   set MSDOSDATA=<drive>:\<directory>
