Is there incremental deployment module for Drupal 7?
There is no Drupal 7 version of Incremental Deploy. In fact, the Drupal 6 version is no longer supported.

You have several options to duplicate the functionality. The closest match is probably Data Export Import -  https://www.drupal.org/project/data_export_import

Other options are the Migrate module - https://www.drupal.org/project/migrate or migrate_d2d - https://www.drupal.org/project/migrate_d2d

Modules for migrating specific content types are also available. For example, for taxonomies, Taxonomy CSV import/export - https://www.drupal.org/project/taxonomy_csv
