DISASTER RECOVERY PLAN By: Matthew Morrow

WHAT HAPPENS WHEN A DISASTER OCCURS  What happens to a business during a disaster?  What steps does a business take to protect their data from being destroyed?  What sort of disasters happen?

TYPES OF DISASTERS  Natural Disasters  Hurricanes  Tornadoes  Earthquakes  Tsunamis  Volcanoes  Etc.  Human Induced  Hackers  Terrorists  Etc.

HOW TO PREPARE FOR A DISASTER  Disaster Recovery Plan  Preventive Measures  Detective Measures  Corrective Measures  No one size fits all  Part of the Business Continuity Plan

RPO AND RTO  RPO - Recovery Point Objective  Represents the point in time of most recent backup prior to any failure  RTO – Recovery Time Objective  How long it can take for an application to come back online after a failure occurs

OTHER REQUIREMENTS FOR D.R.  Performance  Minimal impact on the performance of an application  Consistency  Application properly replicated and restored  Geographic Separation  Primary and backup sites are separated geographically

STRATEGIES FOR DATA PROTECTION  Back ups made into tape and sent off site  Back ups made into disk on-site, with either being automatically copied or sent directly to off site  Replication of data to an off-site location, Storage Area Network  Using Hybrid Cloud solutions

THE CLOUD  Stored in logical pools  A hosting company owns physical storage environment  Companies buy or lease storage capacity  Companies only pay for storage they actually use

TYPES OF BACKUP SITES  Hot  Provides minimal RTO and RPO  Uses synchronous replication  Most expensive

TYPES CONT.  Cold  Data replicated on a periodic basis.  RPO large  Servers not readily available  High RTO  Very low cost

TYPES CONT.  Warm  Can be synchronous or asynchronous  May take a few minutes to bring standby servers online  Cheaper than Hot

IMPORTANT REASONS TO HAVE A D.R. PLAN  For every $1 spent on a DR plan, society saves $4 in response and recovery costs.  If a major loss happened, 43% of businesses never reopen and 29% close within a year.

VIDEOS  

TO SUMMARIZE  Every business should have a plan  There is no one size fits all plan  Want a balance between low cost and low RPOs and RTOs
