Critical services should operate 100% of the time

Critical services should operate 100% of the time

Businesses must seek disaster recovery solutions that ensure their core systems experience as little downtime as possible, according to an industry expert.

Amanda Strassle, IT senior director of data center service delivery at data storage company Seagate Technology, said a company's most important systems need sophisticated protection. 

"It has been our experience that our most critical services (those application services that drive revenue or differentiate our business from our competitors) should operate at 100 per cent availability," she told Help Net Security.

"We utilize extremely high redundancy so failures do not result in an impact to the application service and zero recovery is actually needed."

Recent statistics from the Disaster Recovery Preparedness Benchmark 2014 revealed that 28 per cent of businesses claimed their databases had experienced a loss of functionality for weeks at a time in the last year.

Oracle database users hoping to achieve zero downtime can invest in standby databases, which will failover to a second database when disaster strikes.

This means companies can continue running crucial services when unforeseen circumstances risk bringing productivity to a standstill.

According to Ms Strassle, a well-designed disaster recovery plan should be in effect at every business, particularly as enterprises are collecting more data than ever before. 

"The amount of data we are dealing with today is significantly more. In fact, our business data centers are managing over 30 per cent more data than they were one year ago," she explained.

Delivering a comprehensive disaster recovery plan can be a challenge, but Ms Strassle claimed it is vital to ensure firms are as prepared as possible.

She advised businesses to run regular testing exercises to check whether back-up solutions work according to plan and recovery time objectives can be achieved.

Testing should account for failure scenarios of varying impacts, Ms Strassle suggested, including a "complete site disaster".
