[NTLUG:Discuss] Copying a file to TWO destinations as the same time..

[Stuart Yarus]

If you really want to use tee, try:

    cat file | tee location1 | tee location2 | tee location3

This method uses the original file just once.  The method certainly 
isn't recommended for many or for large files, due to the use and 
duplication of stdout (standard output).

Your backup method should depend on the nature of the backup.
