IBM Tivoli Storage Manager Mail Extension4 Tivoli Data Protection for Lotus Domino Highlights Tivoli Data Protection for Lotus Domino is designed to improve backup and recovery procedures for Lotus Domino databases by providing capabilities that Tivoli Data Protection for Lotus take advantage of changes made to the Lotus Domino server architecture in Domino can improve backup the R5 release. This new architecture includes a specific API for backup and and recovery. recovery of databases. (A similar API is not available in the R4 release.) Tivoli Data Protection for Lotus Domino helps you realize several benefits, such as a more scalable architecture for backup and restore and improved flexibility. It also works to enhance availability by eliminating the need to take Domino databases offline periodically to perform backups using a file-level backup tool. With Tivoli Data Protection for Lotus Domino, you can: • Perform “hot” or online backup of databases • Maintain multiple backup versions of databases • Define an “exclude” list to identify databases that are to be excluded from a backup • Archive transaction log extents (if archival logging is used) • Restore any backup version of an R5 database, and automatically apply changes since the backup from the transaction log • Restore databases to a specific point in time Figure 1: The graphical user interface for Tivoli Data Protection for Lotus Domino.
IBM Tivoli Storage Manager Mail Extension5 Highlights • Expire database backups automatically, based on version limit and retention period • Expire archived transaction logs automatically when they are no longer needed by any version of your database backups • Automate scheduled backups With the backup API, administrators Exploiting Lotus Domino R5 architecture to help improve database backup can perform online backups of and recovery processes individual databases and In the past, administrators have been challenged by the fact that Domino transaction log archives. databases are complex logical structures that often appear to traditional storage management tools as very large data objects in the form of single client files. As a result, backup tools operating only at the operating system level had just one option: back up the entire database. Even if only a few documents were updated within a database, the entire database would have to be backed up since the last point when the modifi- cation time stamp of the database had changed. The limitations of this architecture meant that an enormous amount of data, and multiple backup copies, had to be kept in the designated storage location. It also meant that the extremely large data files in the Domino application had to be transmitted over the company’s LAN on a regular basis to be backed up—straining network resources and requiring a lengthy backup window. The backup and recovery API in Domino R5 provides the capability to perform online full backups of individual databases, plus archives of the transaction log (when archival logging is in effect). Because Tivoli Data Protection for Lotus Domino is built around this backup API provided by the application vendor, it helps maintain the integrity and consistency of your backup data even if the databases are changing while the backup is in progress. The addition of “transaction logging” in the R5 release adds both flexibility and functionality to the backup and restore process. Tivoli Data Protection for Lotus Domino can help you take advantage of this change to implement a production-oriented backup and restore process for your Lotus Domino R5 environment.
IBM Tivoli Storage Manager Mail Extension6 A transaction log is used to capture database changes for logged databases; Highlights full database backups are not required as frequently as they were with previous Domino releases. Updates to a logged database are recorded in the Domino server transaction log. Then, if a recovery is necessary, the database can be restored using the last full backup—augmented by any changes to the database since the last full backup, as recorded in the transaction log. The introduction of transaction logging in R5 creates a new storage management requirement for Lotus Domino environments. Both the logged databases and the transaction log must be backed up regularly, because both types of data objects are required to recover from system and media failures. Archived transaction log extents must be applied to the backup before a database can be fully recovered. Tivoli Data Protection for Lotus Domino works in combination with your Tivoli Storage Manager server to help verify that these vital new data objects are backed up automatically. Tivoli Data Protection for Lotus Online backup and restore Domino can deliver flexibility Tivoli Data Protection for Lotus Domino provides the ability to perform a for better management of “hot” backup for a Lotus Domino server. Using Tivoli Data Protection for backup routines. Lotus Domino, Lotus Domino databases can be backed up during normal operation, without shutting down the server. This capability helps maintain near-24x7 availability for your Lotus Domino applications. Tivoli Data Protection for Lotus Domino also supports many high-performance features, such as the use of parallel sessions to help maximize throughput of backup data and shorten the backup window. By offering enhanced functionality, Tivoli Data Protection for Lotus Domino provides extra flexibility in managing backup routines for Domino databases. For example, you can use it to help implement a backup and recovery process based on a combination of full and incremental backups. Full backups can be scheduled to occur at specific intervals (for example, once a week, during a time slot when user traffic is relatively low). Incremental backups, which require fewer system resources to perform and have less impact on the application’s availability, can occur more frequently. The objective of an incremental backup is to capture only the changes in a database since the last backup. For logged databases, this is done by capturing
IBM Tivoli Storage Manager Mail Extension7 transaction log data from the Domino server—in effect, archiving the “changed” Highlights data in your Domino environment from one full backup to the next. Tivoli Data Protection for Lotus Domino supports two types of incremental backups. In addition to archiving the transaction log (which captures the changes for logged databases), Tivoli Data Protection for Lotus Domino also provides an incremental backup command that backs up only the following: • Any new databases that have not yet been backed up • Nonlogged databases that have changed since the prior backup • Logged databases that need a new full backup because the database instance ID has changed Tivoli Data Protection for Lotus Domino helps maintain the integrity of your backup and recovery process. As new databases are added, they can be included automatically in your established backup procedures. In addition, if your Lotus Domino environment includes nonlogged databases, Tivoli Data Protection for Lotus Domino makes it possible to enroll those nonlogged databases in your backup and recovery scheme. If a recovery is necessary, it can be accomplished by restoring the latest full backup, followed by a restore of the transaction logs that have been archived since that backup, to whatever point in time you specify. Administrators can manage Transaction log support Domino transaction logs with Tivoli Data Protection for Lotus Domino is designed to help you take full the Tivoli solution. advantage of the transaction log capabilities built in to Lotus Domino R5. Tivoli Data Protection for Lotus Domino incorporates several features that let you efficiently manage the transaction logs produced in your Domino environment and exploit their full potential for implementing a robust backup and recovery process. The key features of this transaction log support include: Ability to archive transaction log files: This helps increase availability by minimizing the network traffic required to implement an effective backup and recovery plan for your Domino resources. With transaction log archiving in place, you can use frequent incremental backups to reduce the need for resource-intensive full backups of your Domino databases, which can significantly decrease your backup windows. And because transaction log
IBM Tivoli Storage Manager Mail Extension8 archives are smaller than full database backups, they require less storage space; this gives you the opportunity to use storage resources more efficiently than would be possible with a backup and recovery plan that uses full backups exclusively. Ability to archive the “currently filling” transaction log file: Tivoli Data Protection for Lotus Domino uses the most current version of the backup API provided by Lotus. This API permits all transaction log files to be archived— both those that have reached their 64MB limit and the transaction log file that is currently filling on the Domino server. As a result, all your transaction log data is protected, helping provide a full and complete recovery with virtually no loss of data. Protection against log space overflow: Tivoli Data Protection for Lotus Domino works to maintain the integrity of your Lotus Domino databases by providing “log archive threshold” functionality. This functionality helps guard against a situation where the transaction log fills up the available log space on the server, a condition that would cause the Domino application to grind to a halt. To prevent such an occurrence, Tivoli Data Protection for Lotus Domino provides threshold parameters on the archive log command. This lets you schedule transaction log archiving to occur often (for example, every hour) if necessary—and yet not perform the archive unless the log has reached the threshold you specify (expressed as a percentage of log volume capacity). This helps you avoid affecting the production system unless absolutely necessary during peak periods, while also protecting the Domino environment against “log full” situations. Automatic retrieval of archived transaction log files during database recovery: Tivoli Data Protection for Lotus Domino can help restore archived transaction logs. It lets you complete a real point-in-time recovery of your Domino environment using a combination of full and incremental backups. This involves restoring a full backup, then applying the transactions from the transaction log up to the desired point in time. Tivoli Data Protection for Lotus Domino makes this restore process even easier by providing automatic retrieval of archived transaction logs as necessary. You simply indicate a specific point in time for the database recovery, and Tivoli Data Protection for Lotus Domino will automatically select and apply the transaction log files needed to complete the restore.
IBM Tivoli Storage Manager Mail Extension9 Tivoli Data Protection for Lotus Domino provides an additional level of Highlights protection for your Domino environment by intelligently scanning for any changes to Database Instance IDs (DBIIDs). Occasionally you might take actions that produce DBIID changes, such as performing maintenance work on your servers or completing a scheduled compression of database files. When DBIIDs change because of these actions, your most recent full backup can no longer be used to initiate a system recovery supplemented by transaction log archives. Tivoli Data Protection for Lotus Domino helps protect you against this potential exposure by automatically detecting when DBIIDs have changed. It then initiates a new full backup to capture the changed data, providing the backup files you need to complete a restore. Data protection for clustered environments You may have implemented a clustering strategy in your Lotus Domino environment to enhance the availability of the application and protect against hardware or system failures on a given machine. Tivoli Data Protection for Lotus Domino provides a full set of backup and recovery capabilities when deployed in either one of two common clustered environments: Lotus Domino Cluster or Microsoft Cluster Server. In either case, Tivoli Data Protection for Lotus Domino can intelligently manage backups to help prevent data loss in the event of a failover. With the Tivoli solution, Additional features administrators can restore data Tivoli Data Protection for Lotus Domino provides several additional features down to the individual user level. to help you improve backup and restore performance. It offers a way to achieve fine granularity in your restores—down to the level of individual users and mailboxes. It also gives you the flexibility to restore individual mailboxes to a different location under a different name, making it possible to duplicate mailboxes to a specific point in time and let your users extract individual items or messages. The Tivoli solution offers broad platform support with products available for most major platforms, including Microsoft Windows®, and UNIX® platforms such as Sun™ Solaris™, IBM® AIX® and OS/390® UNIX System Services (USS). On the Windows platform, Tivoli Data Protection for Lotus Domino lets you choose between a graphical user interface (GUI) or a command line interface to perform backup and recovery functions. A version of the Tivoli Data Protection product is available for the IBM OS/400® platform.
IBM Tivoli Storage Manager Mail Extension10 LAN-free backup in SAN environments Highlights Many companies with substantial storage requirements have elected to implement SANs as a way of managing their storage resources more efficiently while also removing storage-related traffic from their LANs. Tivoli Data Protection for Lotus Domino can help you realize additional benefits from your investments in SAN technology. It can perform backups and restores directly through your SAN, helping minimize their impact on the LAN and on LAN-dependent applications and resources. It supports this LAN-free functionality on several platforms: Windows, AIX and Solaris. By communicating with a Lotus How Tivoli Data Protection for Lotus Domino works Domino API, the Tivoli solution Tivoli Data Protection for Lotus Domino supports the Lotus Domino server, can restore data to a specific communicating directly with the backup API provided by Lotus Domino R5. point in time. Based on this communication, Tivoli Data Protection for Lotus Domino can read databases and transaction log files from the disk of the Lotus Domino server, even while the server is online. From there, Tivoli Data Protection for Lotus Domino automatically transfers the data to the Tivoli Storage Manager server. The Tivoli Storage Manager server is responsible for writing the data to defined storage media (direct access storage device, optical and tape). Depending on your environment, backup data can be transferred locally over the LAN or over the SAN. When a restore is required, Tivoli Data Protection for Lotus Domino can handle the whole process automatically. You simply select a database backup version and specify the point in time you want the restore to cover. It then retrieves the full backup you selected from the Tivoli Storage Manager storage device and restores it to the Lotus Domino server. Then Tivoli Data Protection for Lotus Domino automatically retrieves the transaction log files needed for recovery to the point in time you specified. Transactions from these transaction log archives are then applied to the restored full backup to complete the roll-forward recovery. LAN-free implementation If you operate a SAN environment you can use Tivoli Data Protection for Lotus Domino to help manage the connection of your Lotus Domino server to designated storage devices directly over the SAN. In this LAN-free scenario,
IBM Tivoli Storage Manager Mail Extension11 most backup data is transferred over the SAN; only the metadata for the Highlights backup files flows over the LAN to the Tivoli Storage Manager server. This approach lets you offload network traffic from the LAN while still using a centralized Tivoli Storage Manager server to manage the storage of your backup data. Tivoli Data Protection for Tivoli Data Protection for Microsoft Exchange Microsoft Exchange can With Version 2.2 of Tivoli Data Protection for Microsoft Exchange you have maximize the protection a powerful tool for enhancing your backup and recovery procedures for of data in your Microsoft Microsoft Exchange server databases. Exchange databases. Tivoli Data Protection for Microsoft Exchange 2.2 is designed to support both Microsoft Exchange server 5.5 and Microsoft Exchange 2000 server. It uses the backup APIs provided by Microsoft to help maximize the protection of your data and provide a professional, wide-ranging storage management solution for your Exchange environment. Tivoli Data Protection for Microsoft Exchange works in conjunction with your Tivoli Storage Manager server to make it simple for you to: • Perform “hot” online backups of Exchange server storage groups and transaction logs • Maintain multiple versions of Exchange server storage group and transaction log backups • Restore storage group and transaction log backups and replay the transaction log files • Automatically inactivate previous backups when a full backup is performed • Automate scheduled backups • Set automatic expiration of backup objects based on version limit and retention period • Monitor results through the Tivoli Data Protection for Microsoft Exchange activity log and automatically prune the activity log • Query a local Exchange server or a connected Tivoli Storage Manager server for configuration information

IBM Tivoli Storage Manager Mail Extension13 When a backup operation is initiated, Tivoli Data Protection for Microsoft Exchange automatically performs the following actions: • Begins a session with a Tivoli Storage Manager server • Informs the Exchange server that a backup is about to begin • Reads data from the Exchange server and forwards it to the Tivoli Storage Manager server • Informs the Exchange server that the backup has completed • Ends the Tivoli Storage Manager server session Tivoli Data Protection for Microsoft Exchange can produce all the different types of backups specified by Microsoft backup APIs. Full backup: Backs up the specified storage group as well as associated transaction logs. After the storage group and logs are successfully backed up, the log files are deleted. Incremental backup: Backs up only the transaction logs and then deletes them. If the backup fails, the log files will not be deleted. Differential backup: Backs up only the transaction logs but does not delete them. If you perform a full backup and then perform only differential backups, the last full backup plus the latest differential backup has the data needed to bring the storage group back to the most recent state. This type of backup is also called a cumulative incremental backup. Copy backup: Similar to a full backup, except transaction log files are not deleted after the backup. A copy backup can be used to make a full backup of the Exchange server storage group without disrupting regularly scheduled backup procedures that use incremental or differential backups. Database copy backup (Exchange 2000 server only): A special backup function that backs up only the specified database as well as associated transaction logs. The transaction log files are not deleted after the backup. A database copy backup can be used to make a special full backup of the Exchange 2000 server database without disrupting backup procedures that use incremental or differential backups.
IBM Tivoli Storage Manager Mail Extension14 Optimize your backup strategy Highlights Because Tivoli Data Protection for Microsoft Exchange is application-aware, it provides great flexibility for you to develop and implement a backup and The Tivoli solution offers options for restore strategy that meets the needs of your enterprise. Depending on factors a backup and restore strategy. such as network traffic management, your available window for backups and the acceptable time required for a restore, you might choose one of several backup strategies. Full backups only: This strategy is commonly used with Exchange servers that are relatively small, because each backup file contains enough data to restore the entire storage group. The disadvantage is that full backups can take a long time to perform. Full-plus-incremental or full-plus-differential backups: These strategies are commonly used when the normal backup window or network capacity cannot support a full backup on a daily (or more frequent) basis. In these cases, a full backup can be performed periodically (for example, weekly on weekends), supplemented by a more frequent series of incremental or differential backups during which only changed data is backed up. This approach can reduce network traffic and shorten backup windows. However, it also makes the restore process more complex by requiring both the latest full backup and any subsequent incremental backups, or the latest full backup plus the last differential backup, to be restored. Note: You should not mix incremental and differential backups, because doing so can make the restore process unnecessarily complicated and confusing. High-performance features Tivoli Data Protection for Microsoft Exchange incorporates several features that can help improve the overall performance of your Exchange environment. These high-performance features include the following areas:
IBM Tivoli Storage Manager Mail Extension15 Buffering: Tivoli Data Protection for Microsoft Exchange can use asynchronous execution threads to transfer data between the Exchange servers and Tivoli Storage Manager servers, increasing overall throughput. Multiple data buffers are used, to allow one thread to read data from an Exchange server while another thread sends data to the Tivoli Storage Manager server. LAN-free support: If you operate a SAN environment, you can use Tivoli Data Protection for Microsoft Exchange to help avoid network constraints. It can automatically manage the connection of your Exchange server to designated storage devices directly over the SAN. This allows most backup data to be transferred over the SAN, while only the metadata for the backup files flows over the LAN to the Tivoli Storage Manager server.

Cluster support: If you have Exchange server running in a Microsoft Cluster Server environment, Tivoli Data Protection for Microsoft Exchange can intelligently manage backups to help prevent data loss in the event of a failover situation.
IBM Tivoli Storage Manager Mail Extension16 Using Tivoli Data Protection for Microsoft Exchange to optimize restores Tivoli Data Protection for Microsoft Exchange can help simplify the process of performing a restore on your Microsoft Exchange servers. When a restore is required, you can use Tivoli Data Protection for Microsoft Exchange to help complete the process automatically. Depending on the version of Exchange you are running, you are prompted to begin the restore by: • Stopping any running services (Exchange 5.5 server) • Dismounting the databases (Exchange 2000 server) Then, Tivoli Data Protection for Microsoft Exchange takes the following actions: • Starts a session with a Tivoli Storage Manager server • Informs the Exchange server that a restore is about to begin • Restores the specified storage group(s) and logs from the Tivoli Storage Manager server (In a restore performed with Exchange 2000 server, the logs are restored to a temporary location as specified by the user.) • Informs the Exchange server that the restore has completed • Ends the Tivoli Storage Manager server session Depending on the backup strategy you have chosen, Tivoli Data Protection for Microsoft Exchange can help simplify the process of restoring the correct backup objects from the Tivoli Storage Manager server. For example, if you are restoring from an incremental backup, Tivoli Data Protection for Microsoft Exchange can: • Automatically highlight the last full backup in the GUI window and prompt you to initiate the restore • Then automatically highlight the other incremental backups performed since the last full backup and prompt you to initiate the recovery of the appropriate incremental backup files
IBM Tivoli Storage Manager Mail Extension17 If you are restoring from a differential backup, Tivoli Data Protection for Microsoft Exchange can: • Automatically highlight the last full backup in the GUI window and prompt you to initiate the restore • Then automatically highlight the most recent differential backup (but not other differential backups that may have been performed since the last full backup) and prompt you to initiate the recovery of the appropriate differential backup file Using Tivoli Data Protection for Microsoft Exchange in conjunction with the Tivoli Storage Manager backup/archive client can provide complete protection for your Exchange environment. The Tivoli Storage Manager backup/archive client handles many key Exchange elements, such as the active directory and file-level data objects, while Tivoli Data Protection for Microsoft Exchange helps verify that you have the database objects you need to perform a comprehensive restore. On an Exchange 5.5 server, the Tivoli Data Protection for Microsoft Exchange solution can back up and restore: • Directory database and transaction logs • Private and public information store databases and transaction logs On an Exchange 2000 server, the Tivoli Data Protection for Microsoft Exchange solution can back up and restore: • Information store storage groups (databases) and transaction logs • Key management service databases and transaction logs • Site replication service databases and transaction logs
