What is Disaster Recovery as a Service

Disaster Recovery as a Service (DRaaS) is the act of maintaining functionality of critical IT systems in the event of a disaster as offered by a business in exchange for compensation. Disaster recovery is the part of business continuity planning that focuses on IT. DRaaS usually includes, not only data restoration in the event of a disaster, but also planning, testing, reporting, analysis and documentation.

Examples of Disasters

Disasters that could incapacitate critical IT systems include both natural and man-made occurrences. Some examples are listed below:

Natural

  • Tornado
  • Flood
  • Hurricane
  • Wildfire
  • Sinkhole
  • Landslide

Man-Made

  • IT virus/bug
  • Failed Change Implementation
  • Explosion
  • Terrorism
  • Riot
  • Vandalism
  • Hazardous Spills

Common Strategies

Disaster Recovery strategies have become more instantaneous as new technology is developed. The following are common strategies for copying data to a location separate from where central systems are housed, starting with the simplest and ending with the most advanced.

  • Backups made to tapes and physically taken to an offsite location.
  • Backups made to a boot disk and automatically copied to an off site disk.
  • Data is replicated to an off-site location.
  • Private Cloud solutions.
  • Hybrid cloud solutions.
  • High availability systems.
