2 Questions to the Audience

3 What is an IT Disaster What is an IT Disaster? Disaster – the unplanned interruption of normal business processes resulting from the interruption of the IT infrastructure components used to support them. Common Types 1 : 1.

5 Business Continuity versus Disaster Recovery These are not the same thing! Business Continuity (BC): Considers the academic, research and business functioning of the institution as a whole. Includes risk assessment, and plans for functional units and business processes. Potentially wider variety of scenarios to consider. Disaster Recovery (DR): IT activities to enable recovery to an acceptable condition after a disaster. BC includes DR. DR requires guidance from BC to direct priorities and set scope.

6 What is the York DR Plan? Review 2008 Plan Project start: January 2003 Sponsored by CIO and VP Finance and Administration Scope Systems: key information systems Scenarios: localized disaster or failure Intended to be a multi-phase, multi-year project

7 What is the York DR Plan? Engaged functional unit leaders and IT support areas Asked to identify maximum tolerable outage and data loss Surprise: >50% of business processes ranked critical Reality check based on observed impacts from lesser-scale outages VP and AVP consultations were the final step to confirm criticality

8 Risk Management Cost of Incidents Countermeasures Degree of Assurance OptimalCost/Benefit LowHigh

9 What is the York DR Plan? DR Threat Assessment Proximity to heavy industry – Oil depot across street Freight train corridor (chemical spill 1980) Near intersection of major highways (400 & 407) York main campus on flight path of two airports Main data centre in basement of old building with UPS but no generator High pedestrian traffic (Science Library and washrooms upstairs) directly overhead Worst case scenario chosen: Loss of building containing main data centre

10 What is the York DR Plan? By 2008 Secured Telus site for secondary site Identified 4 categories of information systems Recovery Point Objectives (RPO) Recovery Time Objectives (RTO) Strategy defined on style of recovery for each Business owners classified which systems belong in which categories Large infrastructure upgrades identified to meet the RTO/RPOs Planned to annually refresh DR plan

11 2012 DRP Refresh Its been 4 years Big upgrade on storage and core network Acquisition of second on-campus data centre IT department merger And …

20 Goals for 2012 Refresh 2012 Goals Focus on C1 business applications as of 2012 IT staff / office space not in scope Scenario is the loss of a single data centre (not both) Validate the categorization of information systems Gap Analysis for C1 information systems Table-top recovery scenario for supporting infrastructure

21 Methodology Produce the complete UIT-supported application inventory How hard can this be? The one list did not exist Categorize Applications and focus on 2012 C1 Applications Gap Analysis and Planning Tabletop Recovery of supporting infrastructure

22 DR Categories Categories and associated RTOs/RPOs CategorySummaryRecovery Time Objective (RTO) Recovery Point Objective (RPO) Category 1Vital Communications and Emergency Services <= 4 hours<= 15 minutes Category 2Critical Customer / Partner Interfaces and Emergency Systems <= 48 hours<= 15 minutes Category 3Critical Customer / Partner Interfaces and Emergency Systems <=7 days<= 24 hours Category 4Critical Internal Departmental Services and Non-Critical Customer Interface <= 14 days<= 48 hours

23 Application Categorization CIO/Business owners re-categorized the application list Result: information systems changed criticality 2008 C1 – 5 services; C2 – None 2012 C1 – 5 different services; C2 – 7 services

24 C1/C2 Applications Gap Analysis Table-top recovery scenario That is still in service, why?, That does what? When did that start? Documentation, documentation, documentation Update deployment and SOP for services

25 Example Normal Service

26 Example Recovered Service

27 DR of Supporting Infrastructure The Business focuses on applications Document infrastructure service dependencies Determine the services required by Infrastructure groups to complete a recovery ie: Monitoring, secure access, system inventory, recovery documentation, etc Some services are considered Category 0 services ie: storage, network, and power Tabletop recovery exercise

28 Lessons Learned RTOs and RPOs are set by the business not IT IT helps in getting to the real requirement Services evolve and RTOs change Infrastructure capabilities change Identify key technologies Continual Improvement DR is big.. Do it in small chunks DR is not Backup DR Planning can be used in more than just DR

29 Next Steps Review the DR plan for remaining services Asking the DR question up front Disaster RTO/RPO versus Operational RTO/RPO Bring staff space and equipment into scope

30 Questions Chris Russell Director of Information and Communication Technology Infrastructure, York University Rick Smith Lead Architect, York University
