How to send a big set of data from one server to another?

Question

There are two LAMP servers, A and B, in different countries. Once a day A has an updated set of data, that is to be processed on B. What would be the best way to set a communication between them?

Estimated size of an update is 20Mb compressed.

Options that comes to my mind are:

1. curl POST request, uploading compressed data in JSON;
2. SQL dump of a tmp table, compressed, then rsync'ed to B. B watching specific folder for update. Then importing the table and processing;
3. Message Queuing with RabbitMQ or Amazon Simple Queue;
4. ..other option?

Should you have any experience with a similar tasks, please share your thoughts.

选项2，无论是在网络上还是使用ftp，都可以使用cronjobs在计划的时间（可能是在晚上）运行任务。
