When a primary system goes down — whether from a power outage, natural disaster or cyberattack — the question is never “will we be affected?” but “how long will it take to recover?” DC-DR is the answer to that question.


What Is DC-DR?

DC-DR stands for Data Center – Disaster Recovery: a model that pairs a primary data center (Primary DC) with a dedicated disaster recovery site (DR Site). When the primary DC experiences a serious failure, operations are switched — automatically or manually — to the DR Site, ensuring services are not completely interrupted.

The Two Most Important Metrics in DC-DR

When designing a DC-DR solution, there are two key technical indicators every organization must understand:

  • RTO (Recovery Time Objective) — the maximum acceptable time from the moment of failure to the moment systems are back online. For banks, RTO requirements typically range from a few minutes to a few hours.
  • RPO (Recovery Point Objective) — the maximum amount of data loss an organization can tolerate, measured in time. The lower the RPO, the more frequently data must be synchronized between sites.

These two metrics drive every architectural decision and cost consideration in a DR solution.

Why It Matters Most for Financial Institutions

The State Bank of Vietnam and financial regulators require institutions in the sector to maintain clear, regularly tested disaster recovery plans. Even a few hours of banking system downtime can trigger serious consequences — direct financial losses, erosion of customer trust and regulatory exposure.

Operating without a DR Site means the entire business depends on the continued availability of a single location. That is not a risk strategy — it is the absence of one.
