We use S3 for storing millions of entries in our webapp, now we move the whole thing to EC2, EU servers, and we also want to move that S3 data to EU. But the bucket we use is in US, and there seem to be no tool to move whole bucket content to different bucket.
There is also problem on how to synchronize the data later on when we switch to EU bucket, the data that will be created meanwhile while the migration was running.
