| Parameter Name                 | Default Setting | Required | Description                                                                                                                                                                                                                                                                                                        |
| ------------------------------ | --------------- | -------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| API Call Limit                 | Blank           | No       | Limits the maximum number of transactions (queries) to send to Salesforce. This option can help avoid exceeding your organizational limit for transactions per 24-hour period. CopyStorm will stop when this value is exceeded. Usually this parameter is only set for the initial load of the CopyStorm database. |
| API Threshold                  | Blank           | No       | Maximum starting API utilization. When CopyStorm is initializing the data copy, if the current Salesforce API usage is above the provided percentage, the copy job is not started.                                                                                                                                 |
| Maximum Runtime                | Blank           | No       | The maximum number of minutes CopyStorm will run before gracefully shutting down. Leave this blank to disable the time limit.                                                                                                                                                                                      |
| Production Database Protection | Checked         | No       | If Checked, CopyStorm will not allow a production Salesforce database to be overwritten by another Salesforce’s data.                                                                                                                                                                                              |
| Schema Only Backup             | Unchecked       | No       | If Checked, CopyStorm will back up the Salesforce schema, but Salesforce data will not be included. This option is typically used during Salesforce migrations.                                                                                                                                                    |
