enable

S3.BucketVersioning.enable(**kwargs)

Sets the versioning state of an existing bucket.

You can set the versioning state with one of the following values:

Enabled —Enables versioning for the objects in the bucket. All objects added to the bucket receive a unique version ID.

Suspended —Disables versioning for the objects in the bucket. All objects added to the bucket receive the version ID null.

If the versioning state has never been set on a bucket, it has no versioning state; a GetBucketVersioning request does not return a versioning state value.

In order to enable MFA Delete, you must be the bucket owner. If you are the bucket owner and want to enable MFA Delete in the bucket versioning configuration, you must include the x-amz-mfa request header and the Status and the MfaDelete request elements in a request to set the versioning state of the bucket.

Warning

If you have an object expiration lifecycle policy in your non-versioned bucket and you want to maintain the same permanent delete behavior when you enable versioning, you must add a noncurrent expiration policy. The noncurrent expiration lifecycle policy will manage the deletes of the noncurrent object versions in the version-enabled bucket. (A version-enabled bucket maintains one current and zero or more noncurrent object versions.) For more information, see Lifecycle and Versioning.

Request Syntax

response = bucket_versioning.enable(
    ChecksumAlgorithm='CRC32'|'CRC32C'|'SHA1'|'SHA256',
    MFA='string',
    ExpectedBucketOwner='string'
)

Parameters

• ChecksumAlgorithm (string) --

  Indicates the algorithm used to create the checksum for the object when using the SDK. This header will not provide any additional functionality if not using the SDK. When sending this header, there must be a corresponding x-amz-checksum or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request . For more information, see Checking object integrity in the Amazon S3 User Guide .

  If you provide an individual checksum, Amazon S3 ignores any provided ChecksumAlgorithm parameter.

• MFA (string) -- The concatenation of the authentication device's serial number, a space, and the value that is displayed on your authentication device.
• ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).

Returns

None
