To enable incremental copy job with the Data Mover command line, add XML tag enable_incremental_restore and set to "TRUE" after <log_to_event_table> xml tag.

There are a couple of optional parameters under <dsa_options> tag that must be left as UNSPECIFIED. (See Limitations and Caveats and Troubleshooting DELTA Execution Failures sections on when to apply these parameters):
Parameter Name Required Description
ir_allow_write No Used when incremental restore is enabled. Allow write for objects after incremental restore. The valid values are: UNSPECIFIED, TRUE, or FALSE.
ir_execution_type No Used when incremental restore is enabled. Incremental restore execution type. The valid values are: UNSPECIFIED or FULL.
The following example shows all the parameters added to the XML for a DSA incremental copy job:
