TECHNICAL GUIDE: CA ARCserve® Backup
Agent for Lotus Domino
CA ARCserve® Backup Agent for Lotus Domino supports Lotus Domino server versions 7.0, 8.0 and 8.5, including the backup and
recovery of the Lotus Domino Attachment and Object service (DAOS) of IBM’s Lotus Domino 8.5. Lotus Domino 32 bit and 64 bit
Windows server platforms are also supported.
The Lotus Domino DAOS feature helps minimize redundant file attachments by utilizing a separate repository on the Lotus
Domino server for attachments. With DAOS enabled, disk space usage is substantially reduced as Lotus Domino does not save a
separate copy of the attachment. Instead, it saves a reference to each attached file and refers to the same file from multiple
documents in one or more databases on the same server. CA ARCserve Backup Agent for Lotus Domino provides you with the
ability to recover your Lotus Domino server quickly and efficiently in the event of any disaster using the disaster recovery option.
CA ARCserve Backup Agent for Lotus Domino supports backup of all Lotus Domino DAOS supporting files to enable a thorough
recovery of the data. The agent also supports non-DAOS enabled Lotus Domino environments to efficiently backup and restore
Lotus Domino data. The CA ARCserve Backup Agent for Lotus Domino lets you select and submit backup and restore jobs with
ease. You can backup and restore a complete Lotus Domino server or individual objects (database files and trans-action log files)
within the Lotus Domino server.
OVERVIEW
BENEFITS
The CA ARCserve Backup Agent for Lotus Domino provides
services that allow the CA ARCserve Backup Agent for Lotus
Domino to back up and restore databases. It also enables you
to select and restore the Lotus Domino DAOS folder if you
have the DAOS folder on a separate disk from the main Lotus
Notes database.
CA ARCserve Backup Agent for Lotus Domino lets you select
an incremental or a differential backup method and schedule
repeating jobs. It provides the capability to restore databases
and transaction log files to either their original location or to
an alternate location.
When you select a Lotus Domino server to back up data, you
will not see the DAOS objects in the Source tab. However, the
CA ARCserve Backup Agent backs up the referenced DAOS
objects with the databases that contain the corresponding
references.

Enables you to backup any online or offline Lotus Domino
database. When you use online backup, you do not have to
replicate the database, and do not have to stop the Lotus

Frequently Asked Questions

Q:
A:
Can I configure CA ARCserve Backup Agent for Lotus Domino to receive additional debugging information?
Yes, you can enable the debug option and set the corresponding parameter values using the Registry Editor. When you
enable the debug option, the program will generate trace files. The trace file is named as [email protected],
where server name is the name of the selected Lotus Domino server.
Q:
A:
Can I expand the DAOS object folder to view the contents of the folder?
No, you cannot expand the DAOS objects folder, because when there is a large number of NLO files, expanding the
folder to view all of the files affects the performance of CA ARCserve Backup. You cannot restore a specific NLO file,
because the NLO file name is just an ID, which does not help you know the contents of the file.
