4D's backup and restoring settings are available as a separate XML file. 4D uses this file's data to display the options in the Settings dialog box, and whenever a backup or restore operation is launched.

It is possible to retrieve and modify backup parameters using 4D XML commands or via any XML editor.

The XML file storing the backup and restoring preferences is named backup.4DSettings. It is created automatically:

• in the Settings folder of the database (default structure settings),
• and in a Settings folder at the same level as the data file when the User settings mode is enabled.
  For more information on these files, please refer to the  Configuration and trace files section. 

Compatibility Note: The default backup.4DSettings file is named backup.xml and located in the Preferences folder in 4D versions prior to 4D v18. The file is automatically renamed and moved when the database is converted to 4D v18 or higher. 

This manual lists the XML keys used in the backup.4DSettings file. For each key, you will find a description, along with its equivalent option in the Settings dialog box (where applicable), the values accepted, as well as its default value.

For more information about a specific option, please refer to its description in the 4D Design Reference manual.
