Enable Local Continuous Replication on an Exchange 2007 storage group

Learn how to enable Local Continuous Replication on an Exchange Server 2007 storage group with step-by-step instructions, screenshots and script commands.

The LCR feature is enabled on a Storage Group level under the Mailbox subnode, located beneath the Server Configuration work center node in the left pane of the Exchange System Management Console, as shown in Figure 8.2.

  1. To enable LCR for the First Storage Group, select it in the work pane, and click Enable local continuous replication in the Action pane.
  2. The Local Continuous Replication link in the Action pane.

  3. You are reading part 2 from "Managing Local Continuous Replication in Exchange 2007," excerpted from Chapter 8 of the book "How to Cheat at Configuring Exchange Server 2007: Including Outlook Web, Mobile, and Voice Access," by Henrik Walther, copyright 2007, published by Syngress, a division of Elsevier.
    This will bring up the Local Continuous Replication Wizard's Introduction page, shown in Figure 8.3. As you can see, this page shows us the storage group as well as mailbox database name. Because there aren't many interactions on this page, simply click Next.
  4. Now let's specify the path to the LCR files for the respective storage group (see Figure 8.4). For the purpose of this example, we're simply specifying the E: drive, which is a second set of disks on the server. When the location has been specified, we can click Next.
  5. Enable storage group Local Continuous Replication.

  6. On the Mailbox Database page, we have to specify the path to the location of the second copy of the database, as shown in Figure 8.5. When you have done so, click Next.
  7. Specifying the path for the Database Copy.
    Figure 8.5 Specifying the path for the Database Copy. (Click on image for enlarged view.)

  8. We have now reached the step where we enable LCR for the storage group, so let's do so by clicking Enable and see what happens. As shown in Figure 8.6, the Local Continuous Replication Wizard completed successfully. Click Finish.
  9. The Local Continuous Replication feature was enabled with success.
    Figure 8.6 The Local Continuous Replication feature was enabled with success. (Click on image for enlarged view.)

If you would rather enable LCR for a storage group via the EMS, you will have to do so using the Enable-DatabaseCopy and Enable-StorageGroupCopy CMDlets. To enable LCR for the First Storage Group, you would need to first run the following command:

Enable-DatabaseCopy -Identity "EDFS03\First Storage Group\Mailbox Database" -
CopyEDBFilePath:"E:\MailboxLocalCopies\First Storage Group\Mailbox Database.edb"

Then type:

Enable-StorageGroupCopy -Identity "EDFS03\First Storage Group"
-CopyLogFolderPath:"E: \Mailbox\LocalCopies\First Storage Group"
-CopySystemFolderPath:"E: \MailboxLocalCopies\First Storage Group"

Note: Even though we're dealing with a secondary copy of a production database, it's still a best practice to keep the log files and database separated on their own set of disks.

Now notice that the copy status for the First Storage Group has changed to Healthy (see Figure 8.7).

The copy status for the storage group Is healthy.
