Question: To support POSIX, the native NtCreateProcess API supports duplicating a process in order to support fork. In UNIX fork is shortly followed by an exec

To support POSIX, the native NtCreateProcess API supports duplicating a process in order to support fork. In UNIX fork is shortly followed by an exec most of the time. One example where this was used historically was in the Berkeley dump(8S) program which would backup disks to magnetic tape. Fork was used as a way of checkpointing the dump program so it could be restarted if there was an error with the tape device. Give an example of how Windows might do something similar using NtCreateProcess.
