Backing up and recovering data is essential for business continuity, disaster recovery (DR), compliance, and ransomware defense. Cloud platforms like AWS, Azure, and GCP provide native services for implementing robust, automated backup strategies.
1. Backup Types
Data backup is a critical component of business continuity and disaster recovery (BCDR) strategies. There are several types of backups, each offering different trade-offs between time, storage requirements, and restore speed. Understanding these backup types helps design efficient and resilient backup plans tailored to specific organizational needs and RTO/RPO goals.
a. Full Backup
Definition
A full backup creates a complete copy of all selected data — including files, folders, databases, or systems — at a specific point in time, regardless of whether the data has changed since the last backup.
Pros
- Simplest to restore: Only one backup file is needed for recovery.
- Captures full system state: Often includes file metadata, application state, permissions, and system configuration (especially in VM or image-based backups).
