Database Replication

Hi all,

I have two queries rising their heads out of curiosity plus need.

1) Is there any data replication solution so that we could use the local counterpart of our cloud-sql database and keep it in sync with the changes in cloud-sql database?

2) Currently when we are importing just around 3-4 GB of data to my cloud-sql instance, it is taking a hell lot of time. I am wondering what will happen when we'll need to have all my data (around 400GB) to cloud-sql instance :) . Is there, or would there be, any mechanism to make such replication faster, at least to some extent ?

Thanks,
Abhishek
