NTBackup gives error ‘Insufficient disk space ...’


NTBackup (when run with arguments to backup specified drives) appears to start (in that it rewinds the tape) but then generates the error message:

Insufficient disk space. Verify that you
have access to the Working Directory
and there is disk space available.


By ‘Working Directory’ NTBackup is actually referring to the temporary directory. The problem is caused because NTBackup cannot access or create a file in the temporary directory.

Possible Remedies:

  • Check that the environment variable ‘TEMP’ is pointing to a valid directory. Check both the drive letter and directory name. Correct it if it is pointing to an invalid drive and/or directory.
  • Check that there is available free disks space on the drive holding the temporary directory. Make space if necessary.
  • Check that the process running the backup has access rights on the temporary directory.

These notes have been tested with Windows NT4.
