About exclusion and preservation The clone process reads the exclude and preserve lists from the source instance during the early stage of the clone. If you update the exclusion or preserver list before the clone starts, the clone honors those changes even if the clone does not take an on-demand backup.

You want the records on your target instance to remain the same.Scenario 2: Preserving and not excluding a table. You want records on your target Instance to remain the same and records for your source instance to be copied over.Scenario 3: Not preserving and excluding a table. You want records from your source instance not to be copied over and records on your target instance to be removed: The table is empty but usable after the clone.Scenario 4: Not preserving and not excluding a table. You want records from your source instance to replace records on your target instance. Test parameters The following parameters apply to all six scenarios: Source — The clone source (for example, a production instance)Target — The clone target (for example, a non-production instance)sys_temp — A custom table used to demonstrate preservation and exclusion behavior Configuration locations on the source instance: Data Preservers: System Clone > Preserve DataTable Exclusions: System Clone > Exclude Data Default clone settings: Exclude audit and log data — selectedExclude large attachment data — selectedExclude tables specified in Exclusion List — selected Important: If Exclude audit and log data is not selected, the list of table exclusions under Exclude Data is ignored.
