Imprtance f a Plan Why have a Disaster Recvery Plan? Prtect yur data Mitigate risks and csts Prtect the rganizatin s reputatin
Disaster Recvery Scenaris What scenaris shuld an rganizatin plan fr? Weather events Hurricanes Trnades Flding Lightning Strikes Extended pwer utages Netwrk disruptin Facility failures/destructin Ransmware
Disaster Recvery Basics What yu must have Multiple player invlvement Executives IT Staff Applicatin Owners Multiple layers f prtectin Multiple iteratins f testing
Disaster Recvery Basics Wh are the players? Executives Ensures Funding Sets realistic expectatins & acceptable dwn-time Apprves data backup lcatins IT Staff Applicatin Owners Develps, tests and evaluates the plan Prpses disaster recvery site(s) Establishes budget & technlgy needs If needed, implements the plan Develps testing utline & gals Identify participants fr testing Perfrms actual testing Apprves the testing utcme
Disaster Recvery Basics DR Site What is a disaster recvery site? A place t cntinue peratins when yur primary site fails Where is it? On-campus Private/Public Clud C-lcatin Other end f the building Mtel 6 Why d yu need it? Because putting all yur eggs in ne basket.
Disaster Recvery Basics DR Site Ensuring Accessibility Can emplyees cnnect t the data frm a remte lcatin? Internet and electricity available? Did they take their equipment hme with them? Physical lcatin Is there internet and electricity available? Can emplyees drive there? Inclement weather Nn-passable rads Gas shrtages
Disaster Recvery Basics Clud Slutins What is Private/Public Clud? Clud almst always refers t virtual server r applicatins Private Clud: Yu mst likely already wn ne If yu have a virtual server and wn and maintain hardware Public Clud: Yu manage the applicatin Smene else manages and wns the hardware Open t anyne Yu cannt pint t a server and say my data lives here Wh wns the data? Security
Lake Cunty Clerk f Curts Where we were Lake Cunty Clerk s Office - 15 Years Ag: Single, nn-hardened server rm Backed-up physical servers t tape media Sent tapes ffsite t a vault in a building dwn the street Tested restres f a few servers yearly Had nly IT staff d the testing and apprval f the results
Lake Cunty Clerk f Curts Where we are tday Lake Cunty Clerk s Office - Last Eight Years: Multi-site server rms, with the primary being hardened Replicated data strage between server rms Backup data t disk arrays Backup disk arrays t an nsite and ffsite tape cpy Send tapes ffsite weekly Cntinuusly send encrypted backups f select data t nline backup vendr (CrashPlan) Cnduct annual disaster recvery testing with users at disaster recvery site
Lake Cunty Clerk f Curts Where we are ging Starting this year: Dedicated backup appliance High speed Able t munt virtual machines directly frm appliance Mving beynd tape 208 annual wrk hurs saved; r 5.5 weeks a year Semi-private clud strage vendr (Hayes Cmputing) VMware Site Recvery Manager Autmate DR testing and reduce recvery Virtual server strage snapshts Can rll back t previus versins quickly Quarterly disaster recvery testing with users
Lake Cunty Clerk f Curts Layers f Prtectin Current Layers f Prtectin: Dcumented plicies and prcedures Dcumented equipment cnfiguratins Trained staff Server rms at multiple sites Redundant netwrking Replicated data strage Onsite backup, ffsite backup Online backup Multiple wrk lcatins/dr carts
Lake Cunty Clerk f Curts - Testing Prerequisites: Wrk with applicatin wners t determine testing pririties and gals First year typically fcuses n cre prcesses Expand test gals each year Discuss ptential limitatins f the test envirnment Develp a testing sign-ff sheet with agreed-t testing functinality Agree n what a successful test lks like Determine a testing schedule
Lake Cunty Clerk f Curts - Testing Setup: Testing is perfrmed at the actual Disaster Recvery site, using the actual Disaster Recvery hardware Setup DR site: Testing setup is diagrammed fr easy setup by IT staff 20 laptps, fur Disaster Recvery carts, tw printers Testers bring their wn specific equipment and supplies IT staff is scheduled t be available t assist testers
Lake Cunty Clerk f Curts - Testing Actual Testing: Cnducted prir t hurricane seasn First week Administrative services and financial system Secnd week curts Testing in a bubble Simulates, as best we can, an actual disaster scenari in a virtual envirnment In a real event, the nly difference is, the bubble layer will be ppped.
Lake Cunty Clerk f Curts Testing Testing Outcmes: Have participants prvide feedback n the disaster recvery testing befre leaving the test Fllw up n the feedback by meeting with applicatin wners Evaluate and Imprve the plan: Technlgy and business prcesses are cntinually evlving, s yur plan must als Ensure the applicatin wners update their prcesses if needed, based n the test
Activating Yur Disaster Recvery Plan When d yu implement the Disaster Recvery Plan? Nt just fr hurricanes Pwer utages Temprary lss f cnnectivity Ransmware Hw lng d yu wait t take actin? May be different fr each scenari Ransmware Immediate actin Pwer and cnnectivity utages Immediate actin Alternate site activatin after 24 hurs
Summary Make sure yu have a well thught-ut plan Ensure everyne in the rganizatin understands the imprtance f having and testing a plan Disaster recvery testing ften reveals weaknesses in prcesses r the plan itself, s cntinually test yur plan t ensure yu learn frm it, and evlve it as necessary Set the cnditins fr when yu have t activate it, and be ready t activate it!
