Business Continuity & Disaster
Planning Requirements Defined
Business
Continuity and Disaster Planning require data
consistency with the synchronous replication of
data over long-distances and / or journal replication to protect
against local and wide-area disasters. This
technology provides other benefits, including:
-
Maintaining more efficient data currency.
Using synchronous replication over a short
distance in a campus or metropolitan area
cluster provides the highest level of data
currency without undue impact to application
performance.
-
Permitting swift recovery. A
campus/metropolitan cluster implementation
allows for fast automated failovers after a
local area disaster with minimal to no
transaction loss.
-
Permitting recovery even when a disaster
exceeds traditional regional boundaries. A
wide-area disaster could disable both data
centers 1 and 2, but with some manual
interaction, operations can be shifted to
data center 3 and continue after the
disaster.
-
Shifting to staffing outside the disaster
area. A wide-area disaster also affects
people located within the disaster area,
both professionally and personally. By
moving operations out of the region to a
remotely located recovery data center,
operational responsibilities shift to people
not directly affected by the disaster.
Janco has defined a Template with a Backup and
Backup Retention policy that is a complete
policy which can be implemented immediately.
The document is provided in both Word 2003 and
Word 2007 format and is easily modified. This
policy is included in the Disaster Recovery /
Business Continuity Template.
Below is a table from the policy.

26% of All Firms Faced Disaster in Last 5
Years |
|
Janco has found that more than a 26% of its client firms
have faced some sort of a disaster over the past
five years. CIOs need to convince executives in
their enterprise to invest in business
continuity and disaster recovery systems. CIO's
need to effectively communicate that business
continuity and disaster recovery planning is not
just an insurance policy.
CIOs know their systems are vulnerable and they want to do
something about it. In these tough economic
times, it is hard to get funding for business
continuity and disaster recovery. CIOs who tie
business continuity and disaster recovery
planning to mandated compliance needs are more
successful in obtaining the necessary funding.
Many of these same companies consider disaster recovery
investment as a rolling upgrade that
consistently augments existing infrastructure
and application investments rather than a
one-time event that can be delayed.
In one research study by another firm many CIOs
blamed disasters on non-natural disruptions and
incidents. The data shows that 42% of the firms
surveyed said power failure was the most common
cause of
declared disasters and downtime, while 32% cited
hardware failure, and 21% cited network failure.
