Subject: Exactly which product do you have?
IBM Tivoli Storage Manager for Mail is designed to take advantage of transaction logging to accomplish exactly what you are asking for… incremental backups. Home page is here,
“For Lotus Domino databases, this module exploits the “transaction logging” feature of Domino, enabling the capture of just the database changes for logged databases. Thus, full database backups are not required as frequently as in previous Domino releases.”
Data Protection for Lotus Domino helps protect and manage Lotus Domino Server data by making it easy to:
Implement centralized, online, selective and incremental backup of Lotus Domino databases Maintain multiple versions of Domino databases
Maintain multiple versions of Domino database backups
Archive Lotus Domino transaction log files, when archival logging is in effect
Restore backup versions of a Lotus Domino database and apply changes made since the backup from the transaction log
Restore Domino databases to a specific point in time
Recover to same or different Domino server
Expire database backups automatically based on version limit and retention period
Expire archived transaction logs when no longer needed
Obtain online context-sensitive, task, and conceptual help

Automate scheduled backups
Recover one or more archived transaction logs independent of a database recovery
Recover from the loss of the transaction log

Supports Lotus Domino “Individual Mailbox Restore”
Data Protection for Lotus Domino provides two types of database backup, incremental and selective, and a log archive function. Incremental backup provides a conditional backup function that creates a full online backup of Domino databases, when necessary. The specific conditions that determine when a new backup is necessary vary depending on whether the database is logged or not. Selective backup unconditionally backs up the specified databases, unless they are excluded from backup through exclude statements. When archival logging is in effect, changes to logged databases can be captured in between full backups, by archiving the transaction log.
