Case Study - Disaster Recovery Plans & Services
Industry:
Non-Profit
Client:
Confidential
Project:
Off-Site Disaster Recovery
Problem:
This organization needed a major disaster
recovery plan that could restore their entire operation should
a major disaster occur at the main site. The plan needed to
support day-to-day business operations including all applications,
databases, email servers, domain servers, and operating systems.
As part of this overall plan, the IT department wanted to
develop a fail over box for their production system. The idea
was to be able to quickly recover from a failure by restoring
to a clean box only the mission critical systems such as the
operating system, the core database and certain applications.
The major challenge faced by the IT department was to be able
to restore the original applications and database without
having to go through the process of installation (which would
take much longer in the event of a failure). Specifically,
they needed to identify and tackle a large number of system
issues such as which processes to stop, which files to modify
and which steps to automate or perform manually at the time
of the recovery.
Business Solution:
After an extensive analysis of their
systems, Wellington was able to design, build, and implement
the required backup and recovery procedures. This Disaster
Recovery System now allows the client to: efficiently backup
application code and data; quickly recover the database, the
application or both; restore backup information either at
the local site or at remote site, all without extra consideration.
Architecture:
The core element to the recovery strategy
is undoubtedly the backup procedure. A daily process is setup
to tape a backup of the following system components: Oracle
Server, Oracle Web Server, Oracle Forms Server, Oracle Financial
Applications, Physical Database Files.
This tape is collected by the operator and sent to a remote
disaster recovery location. This tape is archived, and to
be used only if a disaster at the main site occurs.
In the event of a disaster, the last tape archived at the
disaster recover location is restored in a clean machine.
At this point the client has to follow a small set of instructions
that quickly configure and brings up the application and database
in their new environment.
Platform:
SUN Enterprise 3500, 4 Ultra SPARCs,
72 GB HDD, SUN Solaris 2.6, Oracle Server 8.0.5, Oracle Financials
11.03.
Benefit:
Now our client has a stable, fully
implemented, production tested Disaster Recovery system. This
gives them the peace of mind of knowing that, if something
terrible happens to the production system, they will be able
to recover their valuable information in a very short period
of time. This system also provides protection for non-fatal
failures like a disk or hardware failures unrelated to the
disaster recovery scheme. |
