In the last year alone, SMBs had to contend with a minimum of five outages, caused mainly by power outages, cyber attacks, upgrades, employee errors, on top of natural disasters, Goh said.

"Disaster preparedness is not just about preparing for the big ones; it's also for those that can occur anytime," he emphasized.

To get around the lack of manpower, Goh suggests SMBs should get all their employees involved in the process of drafting a disaster preparedness plan, so that everyone would know what to do when it strikes.

"It is also important to review your plan," he added. "The IT landscape changes frequently. What's not important last year may be very important to the business this year."
