AppleInsider, and Apple itself, strongly suggest users don't install betas on to 'mission-critical' or primary devices, due to the potential for data loss or other issues. It is instead recommended to install betas onto secondary or non-essential devices, and to ensure there are sufficient backups of important data beforehand.
