question about robocopy

[yawnmoth]

Just to make sure, robocopy's mirror mode copies changed files over,
does it not?

Also, I assume successive runs of "robocopy /mir" is more efficient
than successive formats / full copies? Certainly, it seems like it
should be - just check the last modified date of a file or directory
and skip over it if its the same as the last modified date on the
destination drive.

Finally, why isn't the /xj option ("exclude junctions") the default
behavior by default?
