Title: State Data Center Disaster Recovery Overview

State Data CenterDisaster Recovery Overview
Presented to Disaster Recovery Coordinators
Meeting Date 3/19/2009

SDC Service Continuity View
SDC partially usable
SDC not usable
SDC can be used
Operational Recovery Restoration of normal
service is part of standard rates
Disaster Recovery additional costs apply
Grey area - Expected time to return equipment to
normal service will determine whether DR is
invoked
Impact to service delivery
Outage Impact
Normal Operations
Severity 4
Severity 3
Severity 2
Severity 1
Disaster
Bug or minor issue where application is still
functioning
Major issue with high impact equipment not
usable

Successful DR Requires Cooperation
  • Participating Agency
  • Plans DR based on business needs and priorities
  • Acquires DR services for out-of-scope IT
  • Funds DR planning, backup recovery
  • Prioritizes recovery sequence within agency
  • Tests agency DR plans
  • Determines scope and declares disaster for
    out-of- scope IT
  • Arranges for backups of data and applications
  • Keeps vendor informed of changes
  • SDC
  • Plans internal continuity of service delivery if
    infrastructure must relocate
  • Contracts with DR vendor to provide
    infrastructure environment in case of SDC
    disaster
  • Determines scope and declares SDC disaster to DR
    vendor
  • Coordinates Cross-Agency priority sequencing
  • Tests SDC DR plans
  • Coordinates movement of people, backup
    resources, and communications connectivity
  • Keeps vendor informed of changes
  • Disaster Recovery Vendor
  • Provides environment for disaster recovery and
    testing (hot sites and portable sites)
  • Hosts DR tests
  • May provide consulting and operations support as
    contracted

What BCP Coordinators need to know
  • Who is your DR coordinator?
  • Has your agency done DR planning?
  • What applications are needed to support critical
    business functions?
  • Where are those applications hosted?
  • What are the disaster recovery time objective
    (RTO) and recovery point objective (RPO) for each
    of those applications?
  • Are the applications and their data backed up
    frequently enough to meet RPO?
  • Is the recovery option and grouping of back ups
    for each application reasonable for the RTO?
  • Will the agencys budget planning support the
    cost associated with meeting the desired RTO and
    RPO level?

5
What DR Coordinators need to know
  • Answers to all the questions in What do BCP
    Coordinators need to know, plus
  • Who is your BCP coordinator?
  • What agency infrastructure will need to be
    recovered before recovered applications and data
    will be accessible to users? (e.g., DNS, LDAP,
    Active Directory, networks)
  • What communications vehicles are expected to be
    available during a disaster? (e.g., email,
    blackberry, IM)
  • What are the recovery procedures for agency
    infrastructure, communications, applications, and
    data?
  • What are DR testing plans?
  • What are the procedures for keeping all of this
    up to date?

6
SDC DR Project Actions
  • Develop DR planning framework and templates with
    SunGard
  • Identify, scope and develop backup and recovery
    for SDC core infrastructure and infrastructure
    needed to support agency recovery requirements
  • Assist agencies with identifying and scoping DR
    requirements for their infrastructure,
    applications and data
  • Develop and implement tiered DR strategies
  • Develop DR test plans and execute initial tests
  • Develop and implement DR maintenance process

7
Working with the SDC on DR Planning
  • Submit request for DR planning and preparation
    through normal agency procedures
  • Provide initial information on DR requirements
  • Once potential solutions are scoped and priced,
    get agency approval to proceed
  • Provide detailed planning information
  • Plan agency testing

8
Key data for DR Planning
Needed for getting to more detail
Needed for planning the best recovery strategy
Needed for planning the best backup strategy
  • Needed for
  • estimating cost
  • aggregating need

Definitions for Recovery Timeline
  • MAD Maximum Allowable Downtime the maximum
    amount of time the business can suffer an
    inoperable business process before significant
    negative consequences are felt. Also called
    Maximum Acceptable Outage (MAO), Maximum
    Allowable Outage (MAO), Maximum Acceptable
    Downtime (MAD), Maximum Tolerable Downtime (MTD),
    Maximum Tolerable Outage (MTO), and Maximum
    Tolerable Period of Disruption (MTPD).
  • RPO Recovery Point Objective the amount of IT
    systems data or transaction loss that can be
    tolerated by the business process
  • RTO Recovery Time Objective the time IT
    organizations have to recover their systems to an
    agreed upon operational state so that workers may
    then recover the lost time of the outage to bring
    the business process back to acceptable service
    levels.
  • Work Recovery The work time required to recover
    the lost transactions of the RPO time plus the
    backlog of work created during the system outage.
    Lost transactions must be recovered manually and
    procedures should be in place to accomplish this
    work.
  • Restoration time Time to bring the business
    process back to a state of full business
    continuity protection. Basically this is backing
    up the recovered system and restoring redundancy
    capabilities.
