This topic explains how to use either the Exchange Management Console or the Exchange Management Shell to enable local continuous replication (LCR) for an existing storage group.

After LCR has been enabled for a storage group, it will initially report a status of Initializing. The storage group will change from a status of Initializing to a status of Healthy after one transaction log file has been generated.

LCR cannot be enabled on a Mailbox server that contains one or more standby continuous replication (SCR) targets. Although LCR can be enabled on a Mailbox server that is configured as an SCR source, LCR and SCR targets cannot be combined on the same Mailbox server.

Before You Begin

To perform the following procedures on a computer that has the Mailbox server role installed, the account you use must be delegated the Exchange Server Administrator role and local Administrators group for the target server. For more information about permissions, delegating roles, and the rights that are required to administer Microsoft Exchange Server 2007, see Permission Considerations.

At the end of either procedure, the LCR database copy should be automatically seeded. If for some reason automatic seeding does not take place, you must manually seed the LCR database copy. For detailed steps about how to seed the LCR database copy, see How to Seed a Local Continuous Replication Copy.


To use the Exchange Management Console to enable LCR for an existing storage group

  1. Start the Exchange Management Console.

  2. Expand Microsoft Exchange, expand Server Configuration, and then select Mailbox.

  3. In the result pane, select the Mailbox server that contains the storage group that you want to enable for LCR.

  4. In the work pane, right-click the storage group that you want to enable, and then select Enable Local Continuous Replication. The Enable Storage Group Local Continuous Replication Wizard will start.

  5. On the Introduction page, click Next.

  6. On the Set Paths page, you can specify the locations for the LCR log files and LCR system files by clicking Browse for the appropriate field. Click Next to continue.

  7. The database page appears with the name of the database in the storage group. Use Browse to specify the path for the LCR database file. Click Next to continue.

  8. Review the Configuration Summary information on the Enable page, and verify that the correct paths have been configured. After you have verified the paths, click Enable to enable LCR for the storage group.

  9. After the storage group and database have been enabled for LCR, click Finish to close the wizard.

To use the Exchange Management Shell to enable LCR for an existing storage group

  1. Open the Exchange Management Shell.

  2. Run the following command:

    Copy Code
    Enable-DatabaseCopy -Identity <Server>\<StorageGroup>\<Database> -CopyEDBFilePath:<FullPathIncludingDatabaseFileName>
  3. After the Enable-DataBaseCopy command has successfully completed, run the following command:

    Copy Code
    Enable-StorageGroupCopy -Identity <Server>\<StorageGroup> -CopyLogFolderPath:<FullPath> -CopySystemFolderPath:<FullPath>
