9 Top 5 Myths About DR I backup my data, that should suffice. Less than half of SMBs back up their data weekly or more frequently, and only 23% backup daily. 41% of the SMBs surveyed said that putting together a Disaster Recovery plan never occurred to them.!

10 Top 5 Myths About DR I ve tested my plan once, so I can safely say that 60% of the time, we ll failover every time. 10 Thumbs up!, 2011 Kristian Niemi, kressen, used under CC BY-NC-ND 2.0 license

11 Top 5 Myths About DR I don t need a DR plan. My company can weather the storm or survive whatever disruption may lie ahead. 11

My company can weather the storm or survive whatever disruption may lie ahead. Factoid: 93% of companies that lost their data for 10 days or more filed for bankruptcy within one year of the disaster, and 50% filed for bankruptcy immediately Source: National Archives and Records Administration in Washington 12

13 What We ve Heard from our Customers I know I need DR, but I m not really sure what that should be. Many firms think that a backup of their data is enough Goal of a backup is to enable data restoration A DR plan helps quickly restore operations 13

14 What is Disaster Recovery? DR is a holistic strategy for restoring IT systems that powers business ops Includes: process, policies, people, technology 14 Can t Fail Cafe, 2006 Thomas Hawk, used under CC BY-NC 2.0 license

16 How to Make DR a Goal for 2013 I ve tried to socialize the need for a DR plan, but it isn t considered a priority by senior leadership. How do I convince my boss that the additional cost of resiliency tools are justified? 16

17 Knowing The Impact of Downtime Show your boss that downtime equals dollars lost. The average cost of downtime for an SMB company is about $42,000 per hour. Source: Gartner Research" 17 Burning Money, 2006 Purple Slog, purpleslog, used under CC BY 2.0 license

18 Two Metrics That Help Quantify Impact RPO = Recovery Point Objective How old your data is once it s been restored Über Cool for School! Example: Necktorious, Inc. Retail store located in Hollywood with an ecomm site Selling scarves to the stars Goal: minimize customer transaction data loss Low RPO of 15 minutes 18 ultra super cool, 2006 Malingering used under CC BY-NC-ND 2.0 license

19 Two Metrics That Help Quantify Impact RTO = Recovery Time Objective How long it takes until your users are able to continue normal operations Pretty in Pashmina! Necktorious, Inc. Example Continued: Site downtime equals a loss of $10k+ per hour Ecomm platform on virtualized servers Replicates business-critical VMs every 4 hours Minimize RTO 19 La mi inseparable Pashmina, 2008 Mareluna, used under CC BY-NC-ND 2.0 license

23 VM Replication Quick Overview Helps protects and recover business-critical VMs when disaster strikes Offers geographic redundancy by replicating VMs between Rackspace DCs 23

24 Solving Real-World Problems VM Replication solution was designed by working closely with our beta customer, Virtual, Inc. We had the opportunity to provide feedback on the early-stage replication product and talk through the options that best met our customer s needs. I felt that Rackspace listened carefully to our feedback and even anticipated how we intended to use and implement the solution. - Russell Kuhl, V.P. of Technology at Virtual! 24

25 Common Hurdles with Replication Tools Failover Testing Cost Complexity 25

26 Failover Testing Cost Host-Based vs. Guest-Based Complexity Host-Based Replication Occurs at the hypervisor layer Replication process controlled by VA Replicated VMs are inactive Guest-Based Replication Occurs at the VM layer Replication process controlled by VMs Replicated VMs in target DC are active 26

28 Failover Testing Cost VM Replication is Host-Based Complexity It s Cost-Effective. Replicated VMs in the target site remain off Only pay for the replicated VMs when they are powered on after failover Replicated VMs are powered down once you failback to the source site 28

29 Failover Testing Cost Infrastructure Costs Complexity Redundant infrastructure represents a significant cost. Repurpose redundant hypervisor in secondary DC (e.g. test/dev environment) Downsize the server footprint in the target site to accommodate just critical VMs Consider using less powerful servers, if degraded performance is acceptable 29

31 Failover Testing Cost VM Replication Allows Different Hardware Complexity It reduces the hardware costs related to redundancy. No need to replicate entire source environment simply select specific VMs Heterogeneous storage options are available for target site (e.g. dsan to local) While replicated VMs are powered down, repurpose redundant server 31

32 Failover Testing Cost Lack of Expertise & Assistance Complexity Companies may not have the expertise or manpower, or both. What do I need? Who s going to design it? Who s going to manage and monitor it? Who s going to assist with the failover? Who s going to push the button for failover? Who owns the overall DR strategy? 32

35 Failover Testing Cost Failover Testing Complexity Companies don t test their failover plan enough. Some replication services charge per test expensive The failover/failback process can be risky in production The risk requires extensive planning around every test 35

36 Failover Testing Cost VM Replication - Testing via Snapshot Complexity No disruption to replication during test! VM 2 Snapshot VM 2 VM 1 Replication Continues VM 2 (Powered Off)! Hypervisor 1 Host 1 Hypervisor 2 Host 2 Rackspace DC 1! Rackspace DC 2! 17 36

37 VM Replication Simplifies Failover Testing Failover Testing Cost Complexity Failover testing that s fast, free, and frequent. No charge for failover testing It s quick to setup and doesn t require planning Testing is done in a sandbox environment 37
