IBM ConfidentialBackup Processing: OverviewA backup performed by Data Protection for Exchange creates a copy of anExchange Server storage group on Tivoli Storage Manager server storage. Thebackup includes any associated transaction logs.When a Legacy backup operation is initiated, Data Protection for Exchangeperforms the following actions:1. Begins a session with a Tivoli Storage Manager server.2. Informs the Exchange Server that a backup is ready to begin.3. Forwards data from the Exchange Server to the Tivoli Storage Manager server.4. Informs the Exchange Server that the backup is complete.5. Ends the Tivoli Storage Manager server session.Data Protection for Exchange provides backup and restore functions for theExchange storage groups and associated transaction logs. Data Protection forExchange does not provide a complete disaster recovery solution for an ExchangeServer. In a disaster recovery situation, Data Protection for Exchange only restoresstorage groups. Other files need to be restored in a disaster recovery situation.Refer to your Microsoft Exchange Server documentation for a comprehensivediscussion of disaster recovery considerations.Personal folders and personal address books that are stored on Outlook clients arenot protected by Data Protection for Exchange. The Tivoli Storage ManagerBackup-Archive client can be used on the Outlook client platform to back up andrestore these files. Since the Outlook client normally keeps these files locked whenrunning, you should stop the Outlook client before backing up or restoring thesefiles. Note that since Tivoli Storage Manager Backup-Archive client provides openfile support, you may be able to back up and restore these files while the Outlookclient is running.VSS Backup processing: OverviewIt is important to understand that Data Protection for Exchange VSS Backupoperations are implemented through the Tivoli Storage Manager backup-archiveclient. The client serves as the VSS Requestor that communicates with VSS toaccess the Exchange data in order to create shadow copies of Exchange storagegroups. Thus, Data Protection for Exchange serves as a front end for VSS Backupoperations and performs the following actions when a VSS Backup operation isinitiated:1. Validates the state of Exchange server objects.2. Begins a session with a Tivoli Storage Manager server.3. Verifies that the VSS service is running and that the Exchange writer isavailable.4. The Tivoli Storage Manager VSS Requestor lists the backup componentsthrough the VSS Writer.5. The Tivoli Storage Manager VSS Requestor performs the VSS snapshot backuppreparation stage.6. The Tivoli Storage Manager VSS Requestor performs the actual VSS Backup.7. The Tivoli Storage Manager VSS Requestor performs an integrity check on theVSS Backup.8. The Tivoli Storage Manager VSS Requestor backs up the data (and metadata)to a Tivoli Storage Manager server.
