The following types of Lotus Notes NSF Files can be backed up incrementally:
Table: NSF files that can be backed up incrementally
When a file is backed up incrementally, there is no progress indicator in the Desktop Agent Status view, and only one revision is retained.
Lotus Notes must already be installed before the Desktop Agent is installed. If Lotus Notes is installed after the Desktop Agent, you must run the Desktop Agent installer again to repair the installation. Additionally, if Lotus Notes is open during the Desktop Agent installation, Lotus Notes must be restarted.
Lotus Notes email files can only be backed up incrementally with DLO if the emails have been archived. Once emails are archived, the resulting archive file can be backed up incrementally. See the Lotus Notes documentation for information on archiving emails.
Deleted Lotus Notes email files are not backed up.
See Configuring the Desktop Agent for incremental backup of Lotus Notes files.
