Backing up to mirror

I am looking at this syntax from Books-Online:
BACKUP DATABASE AdventureWorks
TO TAPE = '\\.\tape0'
MIRROR TO TAPE = '\\.\tape1'
MIRROR TO TAPE = '\\.\tape2'
MIRROR TO TAPE = '\\.\tape3'
WITH
FORMAT,
MEDIANAME = 'AdventureWorksSet0'
1. Am I right in thinking that this has nothing to do with database
mirroring? I've never done that either, but I've read that the mirror is
updated through transactions transferred from the database to the mirror, and
also that there can be only one mirror.
2. Can the MIRROR option be set up from the backup dialog screen, or only
through code like the above?> 1. Am I right in thinking that this has nothing to do with database

Correct. The word mirror is overloaded and user in several independent contexts (just like
"snapshot", "schema" and "meta-data").

I haven't found a way to do this through the GUI, so TSQL is the way to go.
