Use the Enable Storage Group Local Continuous Replication Wizard to enable local continuous replication (LCR) for a storage group. LCR is a single-server solution that uses asynchronous log shipping technology to create and maintain a copy of a storage group on a second set of disks that are connected to the same server as the production storage group. LCR provides log shipping, log replay, and a quick switch to a secondary copy of the data. The following sequence represents the LCR life cycle:
- The life cycle starts when a copy is created by configuring a
copy of a storage group. The storage group must exist and have a
defined location for the LCR copy. If databases exist in the
storage group that is being enabled for LCR, the wizard will also
walk you through enabling the databases for LCR.
- When it is designated as a copy, the new LCR storage group can
be seeded. Seeding is the process in which a database, either a
blank database or a copy of the production database, is added to
the storage group copy.
- When seeding is complete, the copy is designated as being in
replay. In this process, the copied transaction log files are being
replayed into the database.
Use this wizard page to confirm that the storage group was successfully enabled for LCR. Click Finish to complete the Enable Local Continuous Replication Wizard.
A status of Completed indicates that the wizard completed the task successfully. A status of Failed indicates that the task was not completed. If the task fails, review the summary for an explanation, and then click Back to make any configuration changes.
The summary pane lists the following fields.
- Management Shell command
This field lists the Exchange Management Shell command that was used to enable LCR. If the task is successful, this text is displayed as Management Shell command completed. If the task fails, this text is displayed as Management Shell command attempted.
- Elapsed Time
This field indicates the amount of time it took for the wizard to complete the task. If the elapsed time is 00:00:00, this indicates that the task took less than 1 second to complete.

Recommended Next Steps
After you have enabled a storage group for LCR, we recommend that you verify the health and status of the storage group copy after it has been seeded. For detailed steps that explain how to view status information, see How to View the Status of a Local Continuous Replication Copy.
