Replication Considerations

Replicating databases is a process of creating and managing duplicate versions of a directory or database. Replicating databases and directories enables you to make changes to one directory, such as importing a policy store, and mirror the changes in the replicated database or directory.

Replicate databases and directories to:

• Improve performance in geographically distributed environments. For example, if there is a Policy Server in London, England and a Policy Server in Boston, Massachusetts, and the policy store is in Boston, you could replicate the policy store database and provide the London office with the replica. By replicating the policy store, both Policy Servers would be accessing the same data. However, the Policy Server in London could now access the replicated policy data faster, while creating less network traffic.
• Safeguard data. Replicating databases enables you to configure failover. If one database is taken off-line to be backed up or fails to respond to a request, the replicated database can be used in its place.
