Data Protector Lotus Integration
The Data Protector Lotus Integration Agent helps to protect and manage Domino Server data by
making it easy to perform the following actions:
• Online backup of the whole Lotus Notes/Domino Server or a specific database
• Centralized, online, full and incremental backup of Lotus Notes/Domino databases
• Restore without performing a recovery
• Restore of backup versions of a Lotus Notes/Domino database and application of changes
made since the backup from the transaction log
• Restore of Lotus Notes/Domino databases to a specific point in time or to the latest possible
consistent state
Lotus Integration concepts
The Data Protector Lotus Integration provides efficient online backup, restore and recovery of Lotus
Notes/Domino Server. It uses the Lotus C API to allow third-party applications to perform online
backups and restores.
The central component of the Data Protector Lotus Integration is the Data Protector ldbar.exe
executable, which is installed on the Lotus Notes/Domino Server system and which controls the
activities between Lotus Notes/Domino Server and Data Protector backup and restore processes.
From the perspective of Lotus Notes/Domino Server, Data Protector is seen as media management
software. On the other hand, the Lotus Notes/Domino Server is a Data Protector client from the
Data Protector Cell Manager’s point of view.
Refer the HP Data Protector Integrations Guide for Lotus Notes to know more about the
backup/restore possibilities.
What is DAOS? (source: IBM)
With the release of version 8.5, an IBM Lotus Domino server employs the Domino attachment and
object service to save significant space at the file level by sharing data identified as identical
between databases (applications) on the same server. Document attachments are the first
components to use the DAOS feature in Lotus Domino.
In databases that use DAOS, Lotus Domino no longer saves a separate and complete copy of
every document attachment. Instead, the server saves a reference to each attached file in an
internal repository, and it refers to the same file from multiple documents in one or more
databases on the same server. When an attached file is large and a message containing it is
broadcast to thousands of users, creating a separate copy of the message for each recipient could
require several gigabytes of disk space. Multiple copies of the same attachment often also
proliferated in mail threads with multiple replies. With DAOS enabled, disk space usage is
substantially reduced.
