Disaster Recovery Issues and Solutions
A White Paper
By Roselinda R. Schulman
Well-planned business continuity and disaster recovery solutions
are critical to organizations operating in 24/7 environments. Minimal
to zero disruption is the goal of today’s enterprises when
faced with planned or unplanned outages. This paper considers the
technological advances that can serve disaster recovery issues,
and the solutions, customer objectives and budgets, that contribute
heavily to the architecting of the most fitting business continuity
solution.
This paper does not address traditional tape backup technology or
its disk declination, but focuses on replication options. It familiarizes
readers with the jargon of software
copy alternatives and defines currently available remote copy techniques,
including network options for replication. In addition, characteristics
are outlined for flexibility, interoperability, and standards compliance
that are required for remote copy operations. This paper concludes
with a rationale for choosing unique, enterprisewide, simple, and
elegant Point-in-Time (PiT) copies and disaster recovery solutions
from Hitachi Data Systems—best-of-breed solutions that support
customers as they strive to reach their business objectives.
