Now let’s see how to begin recovering the old server’s data. Since the users will be still sending and receiving messages, its more complicated than just offline recovery. You won’t be able to do a simple restore from backup because the mailboxes of users contain data that might be overwritten with obsolete data and lose newer messages. It can also have live files related to ongoing transaction that should be considered. So, with these restrictions, you won’t be able to simply restore database. Then, we can achieve the restoring process by first restoring the old server’s database to another location and then merging it with new data on server. For this, we will be using a recovery storage group.

- You can create a recovery storage group by opening the Exchange System Manager and navigating to Administrative Groups | your administrative group | Servers | your server.
- Here, right-click on your server and select the New | Recovery Storage Group commands from the resulting shortcut menu. This will open a Recovery Storage Group Properties sheet.
- Once properties sheet is displayed, you should enter a location for restored transaction logs & system path. You should choose a location that has enough free storage space to restore the information from recovery process. Also, you shouldn’t choose any location that already has an existing server database. If there is enough space, default path will not have any conflicts to existing database. Select OK button and the new recovery storage group will be created.
- Now, you can check the created recovery storage group by expanding the server’s node within the Exchange System Manager. You will notice that there is now a Recovery Storage Group container listed under the server container.
- You can right-click on the Recovery Storage Group container and select the Add Database to Recover command from the resulting shortcut menu. This will open a dialog box to Select Database to Recover by the Exchange System Manager.
- Here, you can find information about current Exchange Server build inside dialog box.
Note: Databases from later versions of Exchange as well as databases from versions of Exchange 2000 prior to Service Pack 3 will not be shown. - You can find a list of all the information stores on lower section of dialog box of server. Now, select the appropriate information store that has right user mailboxes for which you want to restore data and Select OK twice.
- It will take a second to process and soon a new mailbox store will be created under the Recovery Storage Group container. You should NOT try to mount the store, as this might disrupt checkpoint files and thus making the recovery process more complex.
