For a restaurant, POS systems are very critical. They contain sales information, accounting management systems and handle inventory. In addition, purchasing, receiving and product transfers among locations is also stored there. These systems also link to information on sales and customer returns, sales trends and costs and profit analysis. Therefore the restaurant must have some backup and disaster recovery mechanism to be on the safer end from Ransomware attacks.
Usually, ransomware is taken as a regular malware attack. This is not true. A malware needs to present on the system for month in order for it to be really deadly but a ransomware only needs minutes to execute and all of the POS systems are brought down, leaving the business to an immediate halt.

Unless you do so, all your POS transactions will be stopped and for a restaurant that is the main source of revenue.
