Data Backup & Disaster Recovery
Data Backup & Disaster Recovery (BDR) in IT services involves creating secure copies (Backups) of data and having a plan (Disaster Recovery) to restore IT systems and operations after incidents like cyberattacks or failures, ensuring business continuity and minimizing downtime using strategies like cloud replication and failover for resilience against data loss. Backup is the copying process, while DR is the broader strategy to get everything running again, often using the 3-2-1 rule (3 copies, 2 media, 1 offsite) for robust protection.
