Case Study: Daehan City Gas Company achieves continuous availability and rapid disaster recovery with Vision Solutions' Double-Take RecoverNow for AIX

Daehan City Gas Company - Customer Case Study

Daehan City Gas, a Seoul-based energy and safety management firm with about 400 employees and roughly $800M in 2008 revenue, needed uninterrupted access to its AIX-based GIS and other critical IT systems to keep underground gas supplies flowing and meet monthly billing deadlines for about one million customers. Any disruption could harm customers and cost the company up to $500,000 a day, so a reliable disaster recovery solution capable of supporting GIS and MIS applications was essential.

Daehan implemented Double-Take RecoverNow for AIX (running on an IBM pSeries 670 with backups on an IBM i550) to provide continuous replication, cloning without stopping mirroring, and point-in-time recovery. The solution delivered an RPO under one hour and full activation in under four hours, enabling fast dial-back of applications, minimal data loss, reversal of accidental or malicious changes, daily non-disruptive testing, and a significantly more robust disaster recovery and business continuity posture.
