Disaster Recovery is the process, policies and
procedures of restoring operations critical to
the resumption of business, including regaining
access to data (records, hardware, software,
etc.), communications (on campus, internet,
CANARIE, etc.), workspace, and other business
processes after a natural or human-induced
disaster.
Most large companies spend between 2 and 4 of
their IT budget on disaster recovery planning
this is intended to avoid larger losses. Of
companies that had a major loss of computerized
data, 43 never reopen, 51 close within two
years, and only 6 will survive long-term.

What critical systems and data to bring back
while rebuilding DR is not business as usual

Assumptions
  • Dealing only with centrally supported IT
    infrastructure and services
  • Based on the draconian scenario of a total loss
    of the computer room
  • Lesser disasters could make use of parts of the
    overall plan
  • The priorities are set according to University
    priorities - in the event of a disaster we will
    remain open and continue to teach

IST
Four phases
  • Criticality assessment
  • Recoverability assessment
  • Recovery scenarios
  • IT Recovery Plan

IST
Criticality Assessment
  • The purpose of this activity is to
  • Validate the critical functions / processes
  • Confirm the business recovery requirements for
    the critical business processes including
    Recovery Time and Recovery Point Objectives (RTO,
    RPO)
  • Confirm the critical Information Technology
    resource requirements such as hardware, software,
    network and procedures that are required to
    support the critical business processes.

Criticality Assessment
The University of Manitoba identified ten
business units to participate in the criticality
assessment

RTO
The recovery time objective (RTO) is the duration
of time and a service level within which a
business process must be restored after a
disaster in order to avoid unacceptable
consequences associated with a break in
continuity.
RPO
Recovery point objective (RPO) (RPO) describes
the amount of data lost measured in time.
Example If the last available good copy of data
upon an outage was from 18 hours ago, then the
RPO would be 18 hours.

Notes
  • RTO has to include the time to recover the core
    network, application and database servers and
    data as well as testing the recovered system
  • A triage or reality check is necessary - most
    business units will overestimate RTO
  • RTO estimates must be in the context of the
    business unit but also in the context of
    University priorities
  • We discovered that the critical applications are
    not the administrative systems - they are the web
    space, portal and learning management system

15
IST
Recoverability Assessment
The objective of this activity is to identify
gaps between the capability and the recovery
requirements identified by the business as part
of the criticality analysis.
16
IST
Recoverability Assessment
  • Template driven
  • Each group in IST reviewed their server
    infrastructure
  • Classified into core, required for disaster
    recovery and other
  • Application support
  • Desktop
  • Backups
  • Bannatyne campus
  • Database
  • Email
  • Facilities
  • Linux
  • Unix
  • Network
  • Novell
  • Storage
  • Telecommunications
  • Web services
  • Windows
