3 Overview Presented in two parts, this white paper provides an introduction to backing up and restoring data from Exchange Server 2000 and In the examples given, we assume that you are performing full daily backups. When you wish to restore your Exchange Server Information Store, we assume that the rest of your system is already running. We recommend that restorations be performed by qualified personnel. Additional Resources For more information about BackupAssist, please visit: BackupAssist website Microsoft Technet also contains some very detailed articles on Exchange Server. However, these are extremely technical in nature.

5 Part 1: Four Steps to Backing Up Exchange Server Online backup of Exchange Server a feature of Windows Backup (ntbackup) The Windows Backup program includes facilities to perform live, online backups of Exchange server. This means that the Exchange Server does not have to be stopped to perform the backup. BackupAssist leverages this feature of Windows Backup, whilst also working around several bugs in ntbackup to deliver a reliable solution. How to set up BackupAssist for online backups of Exchange Server Step 1: Find your storage groups Launch the Exchange System Manager from the Start menu, and expand the Servers tab as shown in the screenshot. You'll find one or more storage groups listed below the name of your server. In the example, there's one storage group called First Storage Group, under the server named SUGARS. Step 2: Enter the details into BackupAssist Run the BackupAssist Administration Console, and locate the Options tab. Then check the Perform online backup of Exchange Server checkbox (as shown in the following screenshot), enter in the name of your Exchange Server, and add the storage groups to backup. In the example screenshot, the server name SUGARS and storage group First Storage Group have been entered in. 1

6 Also note that for this example, we choose to backup to a file called C:\BA.bks. Step 3: Perform a backup The next step is to either perform a test backup, or to wait for your scheduled daily backup. BackupAssist will backup Exchange Server during the second phase of the backup. During the backup process you'll see a screen like this: 2

7 In the example, the drive called SUGARS\Microsoft Information Store\First Storage Group is being processed. This corresponds to a live backup of your Exchange Server. Step 4: Examine your backup logs The final step to ensuring your Exchange Server was backed up is to examine the backup logs. As shown above, the backup of SUGARS\Microsoft Information Store\First Storage Group resulted in 21,013,392 bytes from 4 directories and 6 files being backed up. The subsequent verify shows the same number of bytes and directories, but as a quirk with ntbackup, the file count is 0. Your restoration should still work this appears to be a problem with ntbackup's report log, rather than the backup itself. 3

8 Part 2: Three Steps to Restoring Exchange Server Restoring Exchange Server through Windows Backup (ntbackup) In this example we go through three steps to perform the restoration. This example follows on from the backup process described in Chapter 1. We assume that your system is functioning properly that all your files and registry have been restored where needed and you need to get your Exchange Server Information Store working again. How to Restore your Backup of Exchange Server Step 1: Dismount your Exchange Server Stores Run the Exchange System Manager from the Start menu, and navigate down to find your server and storage group (as shown in the screenshot). Then on your Mailbox Store and Public Folder Store (and any other stores that may be listed), right click and select Dismount Store. Once dismounted, your stores will have an icon with a red arrow pointing down, as shown in the screenshot below. This indicates that they have been dismounted. 4

9 Step 2: Run Windows Backup, and perform the restoration Start Windows Backup as shown in the screenshot below. You should then click the Restore and Manage Media tab, and locate the file or tape that you wish to restore from. Expand the tree under that media until you find the Exchange Server Information Store listed, and select it. 5

10 In the example screenshot, we are restoring from a file called BA.bks, and the Exchange Server is SUGARS. Click the Start Restore button. You'll be asked several options, as shown below. Because we are restoring to the same Exchange Server, the Restore To field is filled with SUGARS. The temporary location for log and patch files should be any directory with enough free space to perform the restore to (Windows Backup will create the directory if it doesn't arleady exist.) Since we are restoring from a full backup, we also check the last two checkboxes on the window, and then click OK. If you are restoring an incremental or differential backup, you should refer to the Additional Resources listed at the start of this white paper. 6

11 Step 3: Check the logs Once the restore is complete, you should see the following window. Click on the Report button to view the logs. The backup log will show the results of the restore process, as shown below: At this stage, you may also choose to reboot your server. Your Information Store should now be restored and mounted, and operational. Congratulations! 7
