Introduction
Interpharm requires that no data is to be
outsourced or transmitted over shared
bandwidth.
A disused bomb shelter has been
purchased for use as an emergency site.
This recovery ‘cold site’ site has a
dedicated Ethernet over First Mile Point
to Point connection with Berkley Vale
Office.
File server needs to be running
continuously so data stored on
Interpharm’s File Servers is continuously
replicated to the server at the Emergency
Site.
XenServer needs to be installed on the
physical servers so the hard-drives
storing the backup of the virtual servers
at Berkley Vale can be plugged into the
physical servers quickly.
Maximum tolerable outage / Recovery Time Objective
Diagram 1 – MTO and RTO
This plan achieves a recovery time objective (RTO) of 2.5 hours. The maximum tolerable outrage
is 5 hours. Specific Disaster Recovery instructions are specified on page

Level of Protection
(Gould, 2001)
The DR plan will give us between tier 5 and tier
4 recovery times, with no loss of data. This is
the best option for Interpharm.
 It gives Interpharm total control over the
security.
 It provides an off-site location where all
important data can be replicated
instantly. So there is no-chance of losing
important data.
 Equipment is there if needed, but not
running continuously.

Policy Statement
Corporate management has approved the following policy statement
The company shall develop a
comprehensive IT disaster recovery plan.
A formal risk assessment shall be
undertaken to determine the
requirements for the disaster recovery
plan.
The disaster recovery plan should cover
all essential and critical infrastructure
elements, systems and networks, in
accordance with key business activities.
The disaster recovery plan should be
periodically tested in a simulated
environment to ensure that it can be
implemented in emergency situations
and that the management and staff
understand how it is to be executed.
All staff must be made aware of the
disaster recovery plan and their own
respective roles.
The disaster recovery plan is to be kept
up to date to take into account changing
circumstances.
Staff Responsibilities
Staff must report any problems with
connecting with the company network /
Internet and hardware/software faults
with workstations to IT staff members
immediately.
If possible, Disaster Recovery should
only be implemented after IT recovery
officers determine that IT operations
cannot be resumed within the MTO
(Maximum Tolerable Outage).

Disaster Definitions
Key trigger issues at headquarters that would
lead to activation of the DRP are:
• Total loss of all communications
• Total loss of power
• Flooding of the premises
• Loss of the building
When an incident occurs the Emergency
Response Team (ERT) must be activated.
The ERT will then decide the extent to which
the DRP must be invoked. All employees
must be issued a Quick Reference card
containing ERT contact details to
be used in the event of a disaster.
Responsibilities of the ERT are to:
• Respond immediately to a potential
disaster and call emergency services;
• Assess the extent of the disaster and its
impact on the business, IT network, etc.;
• Establish and manage disaster recovery
team to maintain vital services and return
to normal operation;
Ensure employees are notified and allocate
responsibilities and activities as required

Disaster Recovery Implementation
Steps for Disaster Plan
Step 1 Declare Disaster
Before implementing this plan, ensure a disaster has been declared by ERT staff listed it this table
below. Or if the one of the key triggers listed in the disaster definitions occurs.
If none of these people are on-site at the time attempt to contact them in the order listed. One of
the IT staff will contact the CIO and CEO.
