Exchange 2000 database files and transaction log files are stored on one or more of the cluster's shared disk resources. One instance of the Exchange Information Store service (Store.exe) runs for each node, supporting up to four storage groups, with five databases per storage group. However, the total number of storage groups for an active/active cluster cannot exceed four.

Each Exchange virtual server in the cluster that uses these resources has its own set of databases and log files. You back up Exchange databases in your Exchange 2000 clusters using a method similar to that of a stand-alone Exchange 2000 server.
To back up the Exchange databases on your shared disk resources

1. Start Backup on any computer running Exchange 2000 in the Windows 2000 domain forest (clustered or not clustered).
   For information about how to run or schedule backup jobs with Backup, see Using the Windows 2000 Backup Utility for Backup and Restore Processes.
2. Click the Backup tab, and then, in the console tree, expand Microsoft Exchange Server. Under Microsoft Exchange Server, you should see a list of the Exchange 2000 stand-alone servers and Exchange 2000 clustered virtual servers in the Windows 2000 forest of which your Exchange organization is a part.

   Note The Microsoft Exchange node above it is only for backing up Exchange databases of previous versions of Exchange. Expand the cluster's Exchange 2000 virtual server that contains the Exchange databases that you want to back up.

3. Select the databases you want to back up by performing one of these procedures.
   • If you want to back up all storage groups on that server, click the box next to Microsoft Information Store (Figure 6.12).
   • If you want to back up specific storage groups in their entirety, expand Microsoft Information Store, and then click the boxes next to the storage groups you want to back up.
   • If you want to back up specific mailbox stores and public stores in a storage group, expand Microsoft Information Store,
     1. Click the storage group that contains the databases you want to back up.
     2. Then, in the details pane, click the boxes next to the databases you want to back up.
4. Next to the Backup media or file name box (Figure 6.12), click Browse to select the media for your backup. For more information about how to select the media for your backup, see Selecting the Destination for the Backup.
5. Click Start Backup (Figure 6.12).
6. In Backup Job Information, in the Backup description text box, type a backup description, set the options and advanced options, and then click Start Backup. For more information about how to set the options for the backup, see Selecting Options for the Backup.
7. After the backup is complete, verify the backup was successful. For more information about how to verify the success of a backup job, see Checking the Success of a Completed Backup Job.
