Running a survey safely
From LimeSurvey Manual
Once you have activated a survey and started to receive responses it is worthwhile considering the following:
- Export the survey as survey archive immediately and save the .lsa file on a safe location.
- Try not to make changes to the survey. There are some parts of the survey that can still be changed after it has been activated, and while these shouldn't cause problems, it's better to be safe than sorry. Fully test your survey before you activate it and then try to leave it exactly as it is.
- If you are a superadministrator, you can also export the whole database (MySQL only) by choosing the related option from the configuration menu.
