AWS 推出了 S3 Object Lock,保護資料被刪除的可能性

AWS 推出了 S3 Object Lock,可以設定條件鎖住 S3 上的 object,以保護資料不被刪除:「AWS Announces Amazon S3 Object Lock in all AWS Regions」。

這個功能跟會計做帳的概念很像,也就是寫進去後就不能改,也不能刪除,保留一定時間後才移除掉:

You can migrate workloads from existing write-once-read-many (WORM) systems into Amazon S3, and configure S3 Object Lock at the object- and bucket-levels to prevent object version deletions prior to pre-defined Retain Until Dates or Legal Hold Dates.

AWS 提供有兩種模式,一個是 Governance mode,這個模式下可以設定某些 IAM 權限可以移除 S3 Object Lock。另外一個是 Compliance mode,這個模式下連 root account 都不能刪除:

S3 Object Lock can be configured in one of two modes. When deployed in Governance mode, AWS accounts with specific IAM permissions are able to remove object locks from objects. If you require stronger immutability to comply with regulations, you can use Compliance Mode. In Compliance Mode, the protection cannot be removed by any user, including the root account.
