When coming up with an approach to perform disaster recovery on AWS from your on premise environment, you need to look at these layers of your system as individual entities. This is because for each of them their are different tools and approaches.
1. Storage Layer: The storage layer includes multi media files, batch files, log files and any other files that not directly owned by the application or database server. These files are typically on SAN or NAS devices on premise.

2. Database Layer: This would be data files associated with your relational or NoSQL database. There are many database vendor specific tools. So the best approach is typically to use the tool or facility provided by the DB vendor. More information in these blog entries:
