vs. Archiving and Backup
Disaster Recovery
Archiving Backup Disaster Recovery
moving data that is no longer ac:vely used to a separate data storage device for long-‐
term reten:on
making copies of data which may be used to restore the original aHer loss, dele:on,
or corrup:on
the process, policies and procedures related to
preparing for recovery or con:nua:on of technology infrastructure aHer a natural or human-‐induced disaster

a hot topic for businesses worldwide
Examples of Disasters
Flooding and cyclone in Australia Mudslides Rio de Janeiro
Earthquake in New Zealand Tsunami and flooding in Japan Tornados and flooding in USA
Flooding in Taiwan
…and of course, human error…

DR is part of a wider set of policies and controls: Business Con=nuity
What is Disaster Recovery?
Recovery Time Objec:ve (RTO)
How quickly you need this assets to be
recovered? e.g. 1min? 15min? 1hr? 4hrs? 1day?
Recovery Point Objec:ve (RPO)
How ‘fresh’ the recovery must be for the
asset? e.g. zero data loss, 15mins out of date?
