• What is a cold site?

  An empty building with no hardware or data
  it disaster_recovery
• What are the characteristics of a cold site?

  • Empty building
  • Requires backup tapes or equipment
  • Transport people to work at the site
  disaster_recovery cold_site
• What is a hot site?

  • Exact replica of the data center
  • Stocked with hardware: Constantly updated
  • Automated replication of applications and software
  disaster_recovery hot_site
• What are the benefits of a hot site?

  • Quick transition to disaster recovery
  • No installation of hardware or applications needed
  disaster_recovery hot_site
• What is a warm site?

  • Between cold and hot
  • Big room with rack space
  • You bring the hardware and software

• What is the purpose of tabletop exercises?

  • Analyze logistics without a full-scale drill
  • Gather key players for discussion
  disaster_recovery tabletop_exercises
• What are the characteristics of a warm site?

  • Infrastructure available
  • Power and racks present
  • Bring your own data to recover
  disaster_recovery warm_site
• What is a tabletop exercise?

  A meeting where key players simulate a disaster response process around a conference table.
  disaster_recovery exercise
• Why conduct validation tests?

  To ensure everyone knows their roles during an actual disaster event.
  disaster_recovery validation
• What should be avoided during validation tests?

  Touching the production systems.
  disaster_recovery safety
• How often should validation tests be conducted?

  Annually or semi-annually.
  disaster_recovery frequency
• What is the purpose of scheduled update sessions?

  To keep the disaster recovery plan current and effective.
  disaster_recovery updates
• What is essential for effective validation tests?

  Well-defined rules of engagement.
  disaster_recovery rules
• What is a key component of a validation test scenario?

  A specific situation that outlines the steps to follow.
  disaster_recovery scenario
• What should be documented after a validation test?

  What worked well and what needs improvement.
  disaster_recovery documentation
• What is a potential scenario for a validation test?

  A fire destroying the primary data center.
  disaster_recovery scenario
• What is the benefit of a tabletop exercise compared to a full test?

  It is less costly and time-consuming.
