To ensure thorough data protection, TIS also sends an image of its data to the JOS DR site in Kwai Fong every few minutes. "In between the images, we test whether the image is successful, and JOS will advise if the image has any problems," Liu said. "Overall, we find the experience positive."
"Cloud-based DR does not bring direct benefits to the business," Liu concluded. "In normal situations, TIS IT leverages the most reasonable and affordable solution to support DR to protect information and data. If disaster strikes (if, for example, the entire building was consumed by fire), the biggest value we bring to the business is to shorten the site recovery time and continue the business—not just for one office location but the entire global Tesco group as a whole."
