copySource

Specifies the source object for the copy operation. The source object can be up to 5 GB. If the source object is an object that was uploaded by using a multipart upload, the object copy will be a single part object after the source object is copied to the destination bucket.

You specify the value of the copy source in one of two formats, depending on whether you want to access the source object through an access point:

• For objects not accessed through an access point, specify the name of the source bucket and the key of the source object, separated by a slash (/). For example, to copy the object reports/january.pdf from the general purpose bucket awsexamplebucket, use awsexamplebucket/reports/january.pdf. The value must be URL-encoded. To copy the object reports/january.pdf from the directory bucket awsexamplebucket--use1-az5--x-s3, use awsexamplebucket--use1-az5--x-s3/reports/january.pdf. The value must be URL-encoded.

• For objects accessed through access points, specify the Amazon Resource Name (ARN) of the object as accessed through the access point, in the format arn:aws:s3:<Region>:<account-id>:accesspoint/<access-point-name>/object/<key>. For example, to copy the object reports/january.pdf through access point my-access-point owned by account 123456789012 in Region us-west-2, use the URL encoding of arn:aws:s3:us-west-2:123456789012:accesspoint/my-access-point/object/reports/january.pdf. The value must be URL encoded. + Amazon S3 supports copy operations using Access points only when the source and destination buckets are in the same Amazon Web Services Region.

• Access points are not supported by directory buckets. Alternatively, for objects accessed through Amazon S3 on Outposts, specify the ARN of the object as accessed in the format arn:aws:s3-outposts:<Region>:<account-id>:outpost/<outpost-id>/object/<key>. For example, to copy the object reports/january.pdf through outpost my-outpost owned by account 123456789012 in Region us-west-2, use the URL encoding of arn:aws:s3-outposts:us-west-2:123456789012:outpost/my-outpost/object/reports/january.pdf. The value must be URL-encoded.

If your source bucket versioning is enabled, the x-amz-copy-source header by default identifies the current version of an object to copy. If the current version is a delete marker, Amazon S3 behaves as if the object was deleted. To copy a different version, use the versionId query parameter. Specifically, append ?versionId=<version-id> to the value (for example, awsexamplebucket/reports/january.pdf?versionId=QUpfdndhfd8438MNFDN93jdnJFkdmqnh893). If you don't specify a version ID, Amazon S3 copies the latest version of the source object.

If you enable versioning on the destination bucket, Amazon S3 generates a unique version ID for the copied object. This version ID is different from the version ID of the source object. Amazon S3 returns the version ID of the copied object in the x-amz-version-id response header in the response.

If you do not enable versioning or suspend it on the destination bucket, the version ID that Amazon S3 generates in the x-amz-version-id response header is always null.

Directory buckets - S3 Versioning isn't enabled and supported for directory buckets.
