It is recommended to create a backup of your whole D-Lab project after you finished your experiment. Find more information about backup methodes here.

However, analysis within D-Lab do not affect the original raw data. Analyzed data is saved as a layer on top of the original one. You always have access to it by changing the active folder (indicated in blue) by right click on the original folder in the Data Session Explorer under Dikablis Prof. → Field Data → Scene Cam  → Original.
