Back translation involves the use of monolingual data to generate more training data for MT task. A backward intermediate model is trained on the available corpora and then used to generate synthetic data, which is mixed together in the training data Measuring the Impact of Data Augmentation Methods for Extremely Low-Resource NMT explains further.
You're expected to write a script/class to generate additional training data for a given language using the back-translation technique.
