Specifies the number of database pages to be copied in one step.
property PagesPerStep: integer default - 1;
Set the PagesPerStep property to specify the number of database pages to be copied between the source and destination databases in one step of the backup process. If there are still more pages to be copied, then the OnProgress event is triggered, and the backup process continues. Otherwise, the backup process is finished. The copying process is described in detail in the Backup article.
The default property value is -1, which means that the entire database will be copied at once.
