No, this is ineficient too, you write twice the same data.
The important thing is writing directly to the buffer of file.
For the backup thing, yes it is similar, but with unneeded steps,
going straight to save-buffer is better and faster IMO (of course if you
have started writing data in the file buffer)

But the worst thing is the actual version with write-region:

Slow and backup broken.
