Trophies but no PSN account

[Icemage]

I know for a fact that backing up your drive and restoring it will NOT save your trophies. Every time I've used it, I've had to re-sync my trophies with the server.

I have never used the data transfer function, so that may or may not work (I doubtful here as well, due to the fact that things like DLC still need to be re-activated on the new system; not exactly the same thing, but Sony's been fairly particular about how people earn trophies).
