How S3 Lifecycle interacts with other bucket configurations

In addition to S3 Lifecycle configurations, you can associate other configurations with your bucket. This section explains how S3 Lifecycle configuration relates to other bucket configurations.

S3 Lifecycle and S3 Versioning

You can add S3 Lifecycle configurations to unversioned buckets and versioning-enabled buckets. For more information, see Retaining multiple versions of objects with S3 Versioning.

A versioning-enabled bucket maintains one current object version, and zero or more noncurrent object versions. You can define separate lifecycle rules for current and noncurrent object versions.

For more information, see Lifecycle configuration elements.

Important

When you have multiple rules in an S3 Lifecycle configuration, an object can become eligible for multiple S3 Lifecycle actions on the same day. In such cases, Amazon S3 follows these general rules:

• Permanent deletion takes precedence over transition.

• Transition takes precedence over creation of delete markers.

• When an object is eligible for both a S3 Glacier Flexible Retrieval and S3 Standard-IA (or S3 One Zone-IA) transition, Amazon S3 chooses the S3 Glacier Flexible Retrieval transition.

For examples, see Examples of overlapping filters and conflicting lifecycle actions.

S3 Lifecycle configuration on MFA-enabled buckets

S3 Lifecycle configuration on multi-factor authentication (MFA)-enabled buckets isn't supported.

S3 Lifecycle and logging

Amazon S3 Lifecycle actions aren't captured by AWS CloudTrail object level logging. CloudTrail captures API requests made to external Amazon S3 endpoints, whereas S3 Lifecycle actions are performed by using internal Amazon S3 endpoints.

You can enable Amazon S3 server access logs in an S3 bucket to capture S3 Lifecycle-related actions, such as object transitions to another storage class and object expirations that result in permanent deletion or logical deletion. For more information, see Logging requests with server access logging.

If you have logging enabled on your bucket, Amazon S3 server access logs report the results of the following operations.

Operation log	Description
S3.EXPIRE.OBJECT	Amazon S3 permanently deletes the object because of the lifecycle Expiration action.
S3.CREATE.DELETEMARKER	Amazon S3 logically deletes the current version by adding a delete marker in a versioning-enabled bucket.
S3.TRANSITION_SIA.OBJECT	Amazon S3 transitions the object to the S3 Standard-IA storage class.
S3.TRANSITION_ZIA.OBJECT	Amazon S3 transitions the object to the S3 One Zone-IA storage class.
S3.TRANSITION_INT.OBJECT	Amazon S3 transitions the object to the S3 Intelligent-Tiering storage class.
S3.TRANSITION_GIR.OBJECT	Amazon S3 initiates the transition of the object to the S3 Glacier Instant Retrieval storage class.
S3.TRANSITION.OBJECT	Amazon S3 initiates the transition of the object to the S3 Glacier Flexible Retrieval storage class.
S3.TRANSITION_GDA.OBJECT	Amazon S3 initiates the transition of the object to the S3 Glacier Deep Archive storage class.
S3.DELETE.UPLOAD	Amazon S3 aborts an incomplete multipart upload.

Note

Amazon S3 server access log records are delivered on a best-effort basis and can't be used for a complete accounting of all Amazon S3 requests.
