My last few posts were centred around Backup. It makes sense to revisit the 3-2-1 backup Rule, a golden Backup Rule.
The 3-2-1 Backup Rule is a time-tested and widely adopted best practice for ensuring data protection and disaster recovery resilience.
Living in a dynamic, ever-changing technical world, the 3-2-1 Backup Rule has been adapted. One worth mentioning is the 3-2-1-1-0 Rule for mission-critical environments.
Table 2: 3-2-1-1-0 Backup Rule
No matter your Backup considerations, the vendor chosen, or deployment strategy and implementation, the bedrock of the 3-2-1 Backup Rule is resilient data protection. Crucial for a defence against:
- Ransomware
- Hardware failure
- Human error
- Natural disasters
- Cyber sabotage or insider threats
