Immutable Backups
What problem does it target?
Immutable backup solutions address the risk of backup data being altered or deleted by ransomware, malicious insiders, or accidental actions. They ensure that backup copies cannot be changed or erased for a defined retention period.
What does this solution do?
Immutable backup platforms:
- Store backup data in a write-once, read-many (WORM) format
- Prevent modification or deletion of backups during retention
- Integrate with backup and disaster recovery workflows
- Support regulatory compliance and ransomware resilience
Who is this for?
- Organizations concerned about ransomware or insider threats
- Enterprises with compliance or data retention requirements
- IT and security teams managing critical data
Who might not benefit from this?
- Small businesses with minimal data protection needs
- Teams with alternative, effective backup strategies
Pitfalls and remedies
| Pitfall | Remedy |
|---|---|
| Misconfigured retention policies | Regularly review and test settings |
| Limited restore flexibility | Balance immutability with operational needs |
| Cost of storage | Use tiered storage and retention policies |
