When an event causes loss of Master data, the data can be restored from any Replica. The recovery process is in fact a synchronization process in the reverse direction - from a Replica to the Master. You can recover lost data from the Replica to the master -- this option is a synchronization process in the reverse direction and requires you to stop the scenario. Or, you can recover lost data from a certain event or point in time (Data Rewind) -- This option uses a process of stamped checkpoints and user-defined bookmarks to roll corrupt data on the Master back to a time before corruption occurred.
Important! You must stop replication in order to initiate recovery.
