IBM Tivoli Data Protection (TDP) for Domino Basic Introduction and Features


IBM Tivoli Data Protection  (TDP) for Domino is an application that backs up and restores Lotus Domino databases and transaction logs. When archival logging is used on the Domino server, it archives transaction log files and retrieves them as required for a database recovery. Database backups and archived transaction log files are stored on Tivoli Storage Manager server. 
  • Data Protection for Domino communicates with a Tivoli Storage Manager server using the Tivoli Storage Manager application programming interface (API). 
  • Data Protection for Domino communicates with a Domino server using the Lotus Domino API.

How IBM Tivoli Data Protection for Lotus Domino works with Domino Server

Data Protection for Domino helps protect and manage Lotus Domino server data by allowing you to perform the following actions
  • Back up Lotus Domino NSF databases.
  • Back up DB2 enabled Notes databases when a DB2-enabled Domino server is available.
  • Restore DB2 enabled Notes databases when a DB2-enabled Domino server is available.
  • Maintain multiple backup versions of Domino databases.
  • Archive Lotus Domino transaction log files when archival logging is in effect.
  • Restore backup versions of a Lotus Domino database and apply changes since the last backup from the transaction log.
  • Restore Domino databases to a specific point in time.
  • Restore one or more archived transaction log files.
  • Expire database backups automatically based on version limit and retention period.
  • Expire archived transaction log files when no longer needed.
  • Obtain online context-sensitive, task, and conceptual help.
  • View online documentation for Data Protection for Domino.
  • Automate scheduled backups.
  • Restore Domino databases to an alternate server or partition.
  • Access Data Protection for Domino remotely using the Tivoli Storage Manager Web client.
  • Access Data Protection for Domino using the client GUI based on Oracle Javatm.
  • Access Data Protection for Domino using the command-line interface.

Backup only Domino NSF databases using TDP Domino

1) The backup and recovery API in Domino provides the capability to perform these tasks
  • Online full backups of individual databases.
  • Archives of the transaction log when archival logging is in effect.
2) Data Protection for Domino provides two types of database backups and an archive log function
  • Incremental Backup
  • Selective Backup
  • Archive Log Backup
3) The backup strategy you choose should be depending on your specific requirements regarding network traffic, backup window, and acceptable restore times. Your choice of strategy includes selecting the type of backup commands to use and the type of transaction logging to be done on the Domino server.

4) Data Protection for Domino can only back up transaction logs from a Domino server that has archival logging in effect. Transaction logs cannot be backed up from a Domino server that has circular or linear loop logging in effect.

5) Archival logging allows transaction log data to be archived on the Tivoli Storage Manager server so that changes to logged databases can be stored on the Tivoli Storage Manager server without having to perform a full backup. This allows a strategy with less frequent full database backups because changes to logged databases are available for restore in the archived transaction log files.

6) You can either take only Full backups or  Full backup plus regular transaction log archives as a backup plan according to your requirements and available storage resources.

Backup only DB2 enabled Notes databases using TDP Domino
1) The following list provides a brief overview of key DB2 enabled Notes database backup features
  • The entire Domino DB2 database or separate DB2 Groups can be backed up.
  • The backup can be restored to an alternate database.
  • In a disaster recovery situation, the backup can be restored to the original Domino DB2 database.
  • Individual DB2 enabled Notes databases are copied from the alternate DB2 database to the Domino DB2 database.
2) DB2 enabled Notes databases are stored in a DB2 database and managed by a DB2 server. Data Protection for Domino provides the ability to back up the Domino 8 DB2 database and DB2 Groups (table space). 

3) Note that a DB2 enabled Notes backup is significantly different than an NSF backup. An NSF database is backed up directly. A DB2 enabled Notes database is backed up indirectly as a DB2 Group. A DB2 Group (or DB2 table space) is really a collection of one or more DB2 enabled Notes databases.

4) DB2 provides a Tivoli Storage Manager Agent and a utility program (db2adutl) that interfaces with the DB2 Recovery API in order to manage Tivoli Storage Manager objects created on the DB2 server. Data Protection for Domino uses the DB2 Tivoli Storage Manager Agent through the DB2 Recovery API to back up and restore the Domino DB2 database and DB2 Groups (table space).

5) Data Protection for Domino provides three types of database backups:
  • DB2 Database Backup - Data Protection for Domino DB2 database backups create a selective backup image that can be used for disaster recovery of the Domino 8 DB2 database or for restoring individual DB2 enabled Notes databases. Only selective backup (db2selective) is provided for DB2 enabled Notes databases.
  • DB2 Group (table space) Backup - Data Protection for Domino DB2 Group backups create a selective table space backup image. This type of backup can only be performed after the DB2 database is enabled for roll-forward recovery.
  • Full DB2 Database and NSF Database Backup - Data Protection for Domino can perform a selective NSF database backup and a full Domino DB2 database backup in a single operation.
6) The following backup strategies can be used for DB2 enabled Notes database backup.
  • Full DB2 database backups only
  • Full DB2 database backups plus DB2 Group backups
Backup both NSF and DB2 enabled Notes databases using TDP Domino
Domino 8 environments that contain both NSF and DB2 enabled Notes databases can implement the following backup strategy
  • Perform full DB2 database backups and NSF selective backups on a regular basis.
  • Perform routine incremental backups of NSF databases to inactivate backup copies that have been deleted from the Domino server.
  • Perform regular DB2 Group backups if the DB2 database is enabled for rollforward recovery.
  • Perform routine archiving of the transaction log files if archival transaction logging is enabled on the Domino server.
  • Routinely inactivate the Domino server log file and routinely inactivate (and delete) DB2 objects from the Tivoli Storage Manager server.

Restoring NSF and DB2 enabled Notes databases using TDP Domino

Restoring NSF and DB2 enabled Notes databases using TDP Domino is a two-stage recovery process, RESTORE & ACTIVATION.

Restore
  • This is the first step you should do for a complete recovery of NSF and DB2 enabled Notes databases using TDP Domino. In this step it restores a single database or group of databases from Tivoli Storage Manager storage to the Domino server. 
  • You can restore the database to a different database file name or to a different Domino server. 
  • You can also restore a group of databases to a different directory and preserve existing file names. In addition, if you specify a point in time on the restore command, the most recent backup version prior to that time is restored. 
  • To restore a database without applying updates from the transaction log, the two steps can be combined into one step by specifying /activate=yes during the restore command.

Activation
  • This is the second step of the two stage recovery process. This function brings restored databases online for use by the Domino server. 
  • You can optionally apply transactions from the transaction log to update the database. Transactions can be applied up to a specific point in time or up through the most recent changes recorded in the transaction log. If archival logging is in effect, Data Protection for Domino automatically restores archived transaction log files as needed.
