Why and What are Data Movement Solutions for Continuous Business Roselinda R. Schulman, CBCPWorldwide Sales Storage Support
What is Business Continuity? • Continuous Business = Staying in Business • Business Continuity Planningis what companies do to ensure that they can continue operations in the face of planned and unplanned ‘events’. • Provisions for business continuity are driven by an understanding of… • Business impact: assessing the impact of ensuring continuous business • Business processes/risks: assessing the frequency and/or likelihood of planned and unplanned events • Data/availability protection is only one part of business continuity (don’t forget about business-critical processes, logistics, recovery execution plans, etc)
The DR Dynamics of Change • The early 1990s the best companies expected to recover their business operations in three days to within 24hrs of the disaster • Between 1997 and 2000 the best companies expected to recover within 24hrs with minimal loss of data at the point of disaster • The internet driven world has changed all this.. The best companies need to have near zero recovery times with no data loss….
WTC Bombing - 1993 • Fact - When the world Trade Centre was bombed in 1993 with relatively minor damage 150 companies went out of business….
What is expected from your business • If your business does not meet these expectations… • Financial loss will occur - $100K minimum per hour • Potential Asset loss - Information • Liability - Suppliers, Customers and Regulators • Customer Loss • Brand Name or Reputation damage • Investor/Stock Market confidence loss…. • Not all these can be measured financially but all will have an effect on the companies bottom line….

Other Considerations • Its not just Incidents on the scale of September 11th that can impact your business…. • ASX - Australian Stock Exchange - Failed Software Upgrade - 2 Hrs • Virus Attacks • Yahoo • eBay • CCN • AOL • London Stock Exchange - Human Error - Online trading system down all day
Your critical data needs to be protected from: • Human error or sabotage • Feb ‘00 - DDoS attacks against eBay, Amazon and Yahoo • Data corruption • Hardware failures • Sept 00’- Power Outage at an airlines main operations centre played havoc with computers that control air traffic, delaying or affecting 300-400 flights across the US. • Software glitches • Advanced Notice (Planned) Outages • Sudden (Rolling) Disasters • Lingering (Duration) Outages
Terminology • Risk Analysis • Identification of threats • Business Impact Analysis • Establish Value, identify critical resources, establish priority • Recovery Time Objective • Time within which Business Functions or Applications must be restored. • Includes time before disaster declared and time to perform tasks • Recovery Point Objective • The Point in time to which data must be restored to successfully resume processing • Often thought off as time between last backup and when outage occurred
Where Are You Today • Have you recently conducted • BIA, Risk Analysis, Critical records analysis • Correlate Cost vs. Risk • Cost • Cost of Re-Creating data and transactions • Cost of Technologies - storage, network, platforms • Re-engineering costs associated with infrastructure refresh • Risk • Likelihood of event • Cost of downtime ( monetary and reputation) • regulatory/legal penalties for non-compliance • Competitive (dis)advantages
Some Considerations to Start • Solution must meet your goals and objectives • Realistic Expectations need to be set • The Business need will be defined by things like the BIA and Risk Analysis • Subject expertise • What groups/departments are involved • Network, Auditing, Business line • Look at educating different groups within your organization so they better understand some of the issues

Advanced Disaster Recovery • Electronic Vaulting • Files transmitted on a regular basis • Remote Journaling • Remote Mirroring • Real-Time Remote Copy • Hot Standby Site • Active/Active Sites (Clustering, GDPS)
Some More terminology • Real Time Copy • Refers to the mirroring of data, • Should provide an IO consistent copy of that data. • Every Update is Replicated • Point-in-Time Copy (PiT) • refers to a copy of data that that is taken at a specific point in time. Ideally this copy should be IO consistent. • PiT copies are used in many ways including backups and checkpoints. • More recently PiT copies are used as part of architected disaster recovery solutions. • NanoCopy
Disaster Recovery Tiers: Definitions • Tape Back-Up – A Point-in-Time back-up is made to tape and sent off-site. • Available System – System must be available at time of incident • Remote Logging – Either to Tape or Disk • Active System – System is available and software is loaded, ready to run and is often required to run software such as HXRC • Recovery Time Objective (RTO)– Time to resume operation at secondary IT facility… this is the duration of the service interruption. • Recovery Point Objective(RPO) – Worst case time between last back-up and interruption time.
Different Types of Data Require Different Levels of Protection Data Audit Required to Assess Business Criticality, and Cost to Recover Diversity in Data Protection Requirements Completely Duplicated/ Interconnected hot-site Remote Disk Mirroring More Disk Mirroring Shared Disk Disk Consolidation Single Disk Copy Electronic Vaulting Importance of Data Tape On-site Tape Back-up Off-site (trucks) More Amount of Data Less Immediate Recovery Time Less Delayed
Recovery Tiers – What is the right one • There is no wrong one • More important is meeting the objectives • Have you other options other than Real-Time replication • If you have a 24 hour RPO you may not need it • The higher the tier, typically the greater the cost and complexity • Combinations or hybrids may be appropriate
Considerations when Architecting Continuous Business Solutions • Planning, Planning Planning • Document, Document, Document • Solutions must accommodate multiple environments and Businesses • What is the right solution • software, hardware, real-time, PiT, multiple • Careful analysis is required • Application types, amount of data • Performance requirements, remote site location • Transmission capability/cost • What are the future requirements
Solution Design • Detailed Assessment Typically Required • Questionnaire/Interviews • Planning Session • Performance data • Data Analysis • How Much, Where, Placement • Current Infrastructure • Will need to match goals and objectives along the the cost • Customers may have to consider reengineering of applications or placement of data • May take a couple of iterations and customer feedback before final design
Real-Time Mirroring Technologies • Options for Consideration • Synchronous Remote Copy • Asynchronous Remote Copy • Hardware based • Software Based • Log Replication • Application Level Copy • All are Viable • Depends on Many Factors • Performance, Cost, type of data, platform etc.
And it doesn't end there • Make sure you have a Baseline • Change control is critical • Impact must be carefully considered • Procedures need to be up to date • Ongoing monitoring of environment • Network • Subsystem response time • Disaster Recovery Testing • Frequency • Document and fix
