Bug: Incremental Synchronization Reads All Export_*.csv Files Instead of Target File

NIM SaaS & OnPrem 6.2

We’ve identified an issue with incremental synchronization, which does not behave as expected.

We declare a connection in the configuration using a specific identifier.
The agent is expected to:

  • Export the target system into a file located at
    Temp/ExportOutput/Export_"Connection_Name"_entries.csv

  • Import only the lines from this file into the database via the SyncTask

However, this is not what happens.

The ExportTask actually processes and exports lines from all files matching:
Temp/ExportOutput/Export_"Connection_Name"_entries.*.csv

How we reproduced the issue

  • We created a copy of an older version of the export file containing 5,000 lines

  • The original export file (Export_"Connection_Name"_entries.csv) was empty

  • Despite this, the ExportTask processed a total of 5,000 lines

Current impact

  • No illegitimate lines have been written to the database so far (good news)

  • However, the behavior is incorrect and prolongs computation, it could lead to unexpected results

Has anyone else encountered this behavior, or is there a known fix or configuration to limit the synchronization strictly to the main export file?

Thanks for the detailed write-up and for clearly outlining the reproduction steps and current impact. That level of detail is genuinely helpful.

Given the nature of the behavior you’re describing and the potential for unexpected side effects in synchronization, this would be best handled through the formal support process. That allows us to review logs, configuration specifics, and environment details properly, and to track the investigation through to a confirmed resolution or workaround.

I’d recommend opening a support ticket via the Netwrix Support Portal:

Once the ticket is open, the support team can engage engineering if needed and provide definitive guidance on whether this is a known issue, configuration-related, or something that requires a fix.

Appreciate you raising this, and looking forward to getting it properly sorted.
