# Instance Data Replication reference

These reference topics provide additional information about data privacy in Instance Data Replication \(IDR\) and domain separation.

-   **[Data privacy in Instance Data Replication](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/servicenow-platform/instance-data-replication-idr/data-privacy-consumers-idr.md)**  
The ability of replication sets to host multiple remote consumers in Instance Data Replication \(IDR\) means that there are potential data privacy issues to consider.
-   **[Adapter descriptions for Instance Data Replication](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/servicenow-platform/instance-data-replication-idr/adapter-descriptions.md)**  
Adapters modify the producer data before inserting the data on consumer instances in Instance Data Replication \(IDR\).
-   **[Excluded tables in Instance Data Replication](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/servicenow-platform/instance-data-replication-idr/IDR-excluded-tables.md)**  
You can't replicate certain tables in Instance Data Replication \(IDR\). Child tables of tables in the exclusion list are also excluded.
-   **[Domain separation and IDR](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/servicenow-platform/instance-data-replication-idr/instance-data-replication-domain-separation.md)**  
Instance Data Replication \(IDR\) functions at the data level, which means it does not explicitly support domain separation.
-   **[Instance Data Replication system properties](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/servicenow-platform/instance-data-replication-idr/instance-data-replication-properties.md)**  
These system properties control the behavior of the Instance Data Replication \(IDR\) application.
-   **[Instance Data Replication roles](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/servicenow-platform/instance-data-replication-idr/instance-data-replication-roles.md)**  
Instance Data Replication \(IDR\) is installed with these roles.
