Back-up one MBL to another MBL

I just bought two My Book Live hard drives. I want to back up my data from one MBL to the other. Is it possible to automate the process to back-up a couple of times a day. Any help would be appreciated.

You may creafe a Safeponit, you can find more details in MBL user manual, page 88:  http://www.wdc.com/wdproducts/library/UM/ENG/4779-705058.pdf
