Backup strategies
Disaster Recovery (DR) Planning Explained
DR planning is critical for ensuring business continuity, minimizing downtime, protecting data, and establishing accountability. It involves risk assessment, identifying critical systems, defining backup strategies, developing recovery plans, and conducting regular testing.
