Questionnaires are versioned during on-line operations. This allows tracking all changes made in the questionnaire during subsequent publishing.

Questionnaire versions are stored in the Administration -> Project backups. section. In order to limit disk space usage, versions are saved without audio and video files. Additionally, these files are automatically deleted after 2 months.
