Dumping multiple Folders

How would i go about dumping my /home/ directory and my /root directory

i currently have.....

dump -f /root/backup.dp /home/ /root/

...but dump only seems to see only my first source directory and not the second (/root in this case)

anyone know a way around this..or if it is even possible?

You might try using tar instead. If you were dumping to a tape, you could dump the first without rewinding the tape, and then dump the second. I don't believe you can do this to a file.

(Post your OS and version next time please).
