1. Approaches to Disaster Recovery in Schools Maurice Cummins, Monte and Ian Ralph, SCEGGS

2. This session: 3 Parts: – Some time to complete our survey – SCEGGS’ DR journey so far – Review of the survey results Aims – Broaden understanding of DR – Source the wisdom of crowds

3. 10 Minutes to complete Survey http://www.surveymonkey.com/s/KZ5J9L3

4. Some Scenarios & Consequences Scenarios – A/C failure – Earthquake – Fire – Plane Crash – Disease outbreak Consequences – Devices fail – Inability to access site – Key staff gone/unavailable

5. Where we would like to be Initially (1 day or less) – Website – Communications (parent portal e-mail, SMS, LMS) – School Admin system online (contacts, payroll etc) After a few days – 1 week (users have devices) – Files – Remote access – Other systems – e.g. Mahara

6. Where SCEGGS is now Tapes Offsite Purchase bare metal Rebuild Restore Reconnect Weeks of labour-intensive effort

7. New technologies – new opportunities Enabling Technologies  VMs  Cloud based VMs  SANs  SAN to SAN replication  iSCSi  External Bandwidth – 1Gbps – 10Gbps  VOIP/SIP trunking for VOIP redundancy  Virtual Apps and or Virtual Desktops for key users in DR  Cloud Storage  Virtual Networking – software defined networking (e.g virtual firewalls  Cluster capable servers for redundancy

8. Considerations for all options Monitoring – is your DR solution online? Access to competent 3 rd parties to advise and minimise risk Make sure that 3 rd party knows your system before accepting a proposal Test regularly – you only know if your backup works when you try a restore Think DR for future purchases

9. Options – On Site Physically remote server room Replicate Hardware AC + UPS Redundant diverse path connectivity FC tape backup in remote location – doing now PlusesMinuses  Least Cost  High speed connectivity  Easily accessible  Vulnerable  Connectivity issues if site destroyed  Access issues cf. Christchurch  Power issues

10. On Site physical separation

11. Tape backup

12. Diverse Connectivity

13. Remote server space

14. Off-site – rack space at other school Assumes – Rack space + AC + UPS + High Speed connectivity Sufficiently remote Replicate hardware Reciprocate PlusesMinuses  Low ongoing costs  Safe location(?)  Connection setup complex  Not School’s core business  Shared connection or purchase independently (adds to cost)  Physical/data security

15. How much rack space?

16. Off-site – rack space commercial facility E.g. Global Switch $1695/Month for 40RU Physically remote server room Replicate Hardware PlusesMinuses  Physically Secure  High availability power and cooling  Core business  Good/redundant connectivity  Low ongoing costs  Safe location(?)  Connectivity could be complex  Access for contractors could be tricky  Need to keep 2 sets of hardware up to date

17. Off-site – 3 rd Party replication Integrator like Netstrategy/Sommerville/ASI Physically remote server room Replicate our Hardware Partner certified on your hardware/software PlusesMinuses  End to end solution  Complexity for integrator to sort  Physically Secure  High availability power and cooling  Core business  Good/redundant connectivity  Specify annual DR test  Integrator staff/documentation to step in if needed  Cost – but expense not cap-ex

18. Off-Site – Cloud E.g AWS Redundant Data Centres PlusesMinuses  Low costs until system used  Physically Secure  High availability power and cooling  Core business  Good/redundant connectivity  Data replicated  Complexity of setup related to addressing/interoperability  No native support of vSphere  Partner definitely required  Costs grow depending on data usage/storage/VM Specs  Complexity of address space  Potential issues of data sovereignty

19. Off-site – cloud for some services Google Docs Office 365 PlusesMinuses  Relatively inexpensive/FTE option  Simple well understood  Physically secure  High availability  Core business  Good/redundant connectivity  Data replicated  Applications also cloud based  Generous storage allowance  Limited scope of solution  Risk 3 rd party ceases to operate  Potential issues of data sovereignty  Some interoperability issues  Complexity for more than simple workloads  Latency when data centre offshore  If LDAP used what happens when AD disappears?

20. Hybrid E.G. Cloud (Google docs/Office 365) + On Site PlusesMinuses  Best of both worlds  Lowers requirements for H/W on site Connectivity Cost  In theory - no interruption to Cloud services  Same issues with Cloud as already mentioned  Same issues with On Site as already mentioned

21. How to choose? Resilience – will the solution survive a catastrophe? Recovery Time – how quickly can we be back online Complexity Connectivity Flexibility Support Cost

22. A selection Matrix Weighted scores Each school needs to develop weights
