Power cuts have forced seven UK companies to activate disaster recovery plans in the past four weeks, according to SunGard Availability Services (AS).
Keith Tilley, managing director of SunGard AS Europe, said that, although the seven outages were unrelated, power failures are one of the main causes for companies falling back on disaster recovery services.
Downtime caused by software and hardware upgrades is the other main reason for businesses to activate plans.
Despite the increased awareness of disaster recovery since 11 September, Tilley explained that such attacks were not the main reason for putting a plan in place.
"The majority of our incidents are mundane," he said. "Seven in the last four weeks have been power related. [Because of disaster recovery plans] it's not front page news and their customers don't know that it is an issue."
But Tilley indicated that companies have been reassessing their plans since September.
"We've seen a surge in testing, which has identified shortfalls in things like the number of telephones, and a realisation of how many paper records there still are," he said.
"There's a peak where you need additional telephone capacity and that's something that we've learned. It's mundane stuff but it has an effect on business."
The company is in the process of acquiring Guardian IT, which Tilley said is going as planned. "We don't anticipate any problems," he confirmed.
SunGard AS president Jim Simmons said: "Guardian IT's assets are complementary. The customers I've spoken to in the UK are happy.
"Bigger is better because it gives them more choice for recovery, which makes for better planning.
"We have a large base of customers to share out our investments in technology and that will bring down costs for customers."
Simmons suggested that some companies' disaster recovery should be just another node on their network.
But for others disaster recovery is central to their day-to-day running, with some customers load balancing vital systems, such as online booking applications, between their own systems and SunGard's.
"The trend is towards shorter windows of downtime and there is an increase in the number of applications. We are moving up the chain," Simmons concluded.
