Definition

DR, or Disaster Recovery, refers to the strategies and processes put in place to recover and protect a business IT infrastructure in the event of a disaster. This includes natural disasters, cyber-attacks, or any event that disrupts normal operations. Effective DR plans ensure that critical systems and data can be restored quickly and efficiently, minimizing downtime and data loss.
