At a Exchange session the speaker revealed that the Exchange team is researching “log shipping” support for the next version of Exchange, just like SQL has log shipping.

What is Log Shipping (in SQL)

Essentially, log shipping is the process of automating the backup of database and transaction log files on a production SQL server, and then restoring them onto a standby server. But this is not all. The key feature of log shipping is that is will automatically backup transaction logs throughout the day (for whatever interval you specify) and automatically restore them on the standby server. This in effect keeps the two SQL Servers in "synch". Should the production server fail, all you have to do is point the users to the new server, and you are all set. Well, its not really that easy, but it comes close if you put enough effort into your log shipping setup. more on sql log shipping at this source
