Shouldn't you copy the file to another drive?

Technically that would mean that one copy of the file is no longer updated when the other is.

You should consider using ln bkp.tar.gz bkp2.tar.gz instead.

loop {
    rsync -tu bkp.tar.gz bkp2.tar.gz
    rsync -tu bkp2.tar.gz bkp.tar.gz
}

rsync -va /media/pi5tb/ /media/pi5tb_backup/
