S3 Object Lock and Immutability Planning

Object Lock and immutability features are configuration-dependent and should be confirmed during provisioning. Where available and correctly configured, retention controls can reduce the risk of deletion or overwrite.

πŸ“‹ Prerequisites

  • Retention durations and compliance scope decided before provisioning
  • A restore-test plan with independent backups

Step-by-Step Instructions

1

Confirm availability during review

State Object Lock, retention mode and Veeam requirements in the provisioning request so the configuration can be confirmed.

2

Validate with a restore test

Test locked-object retention and restores before production cutover, alongside least-privilege access and credential isolation.

3

Keep independent backups

No storage control provides absolute protection from ransomware or data loss. Maintain independent verified backups and monitoring.

πŸ“Œ Important Notes

  • 3x data replication provides redundancy and resilience; it is not a substitute for tested backups.
