Recovery Database in Exchange Server 2013

In the previous two article we have learnt how to Backup and Restore Exchange Server 2013 database using Windows Server Backup. In this article we would be focusing on how to create Recovery Database (Aka RDB).
It is very important to understand in what scenario RDB can be useful. Lets first understand the scenario.
  1. A user has deleted some important emails and that needs to be recovered. Without restoring the data to production we would be creating RDB.
  2. Single Mailbox or the entire database needs to be restored. Etc.
Note :- In both the scenario the database has crossed the default retention limit.
To know how to backup Exchange Server 2013 using Windows Server Backup 2012. Please follow the below article.
To know how to restore the Data from Backup. Please follow the below article.
=====================================================
We will be using the same database which was restored. Before creating RDB we will first understand the database health.

Figure 1.2 : State : Dirty Shutdown
In figure 1.2 since the database was restored. It will be always be in “Dirty Shutdown”. We sill be performing soft recovery by running the below command.
