Creates a copy of an object that is already stored in Amazon S3.
You can store individual objects of up to 5 TB in Amazon S3. You create a copy of
your object up to 5 GB in size in a single atomic action using this API. However,
to copy an object greater than 5 GB, you must use the multipart upload Upload Part
- Copy (UploadPartCopy) API. For more information, see Copy
Object Using the REST Multipart Upload API.
You can copy individual objects between general purpose buckets, between directory buckets, and between general purpose buckets and directory buckets.
Amazon S3 supports copy operations using Multi-Region Access Points only as a destination when using the Multi-Region Access Point ARN.
Directory buckets - For directory buckets, you must make requests for this
API operation to the Zonal endpoint. These endpoints support virtual-hosted-style
requests in the format https://bucket_name.s3express-az_id.region.amazonaws.com/key-name
. Path-style requests are not supported. For more information, see Regional
and Zonal endpoints in the Amazon S3 User Guide.
VPC endpoints don't support cross-Region requests (including copies). If you're using VPC endpoints, your source and destination buckets should be in the same Amazon Web Services Region as your VPC endpoint.
Both the Region that you want to copy the object from and the Region that you want to copy the object to must be enabled for your account. For more information about how to enable a Region for your account, see Enable or disable a Region for standalone accounts in the Amazon Web Services Account Management Guide.
Amazon S3 transfer acceleration does not support cross-Region copies. If you request
a cross-Region copy using a transfer acceleration endpoint, you get a 400 Bad Request
error. For more information, see Transfer
Acceleration.
All CopyObject
requests must be authenticated and signed by using IAM credentials
(access key ID and secret access key for the IAM identities). All headers with the
x-amz-
prefix, including x-amz-copy-source
, must be signed. For more
information, see REST
Authentication.
Directory buckets - You must use the IAM credentials to authenticate and authorize
your access to the CopyObject
API operation, instead of using the temporary
security credentials through the CreateSession
API operation.
Amazon Web Services CLI or SDKs handles authentication and authorization on your behalf.
You must have read access to the source object and write access to the destination bucket.
General purpose bucket permissions - You must have permissions in an IAM policy
based on the source and destination bucket types in a CopyObject
operation.
If the source object is in a general purpose bucket, you must have s3:GetObject
permission to read the source object that is being copied.
If the destination bucket is a general purpose bucket, you must have s3:PutObject
permission to write the object copy to the destination bucket.
Directory bucket permissions - You must have permissions in a bucket policy
or an IAM identity-based policy based on the source and destination bucket types in
a CopyObject
operation.
If the source object that you want to copy is in a directory bucket, you must have
the s3express:CreateSession
permission in the Action
element
of a policy to read the object. By default, the session is in the ReadWrite
mode. If you want to restrict the access, you can explicitly set the s3express:SessionMode
condition key to ReadOnly
on the copy source bucket.
If the copy destination is a directory bucket, you must have the s3express:CreateSession
permission in the Action
element of a policy to write the object to the
destination. The s3express:SessionMode
condition key can't be set to ReadOnly
on the copy destination bucket.
For example policies, see Example bucket policies for S3 Express One Zone and Amazon Web Services Identity and Access Management (IAM) identity-based policies for S3 Express One Zone in the Amazon S3 User Guide.
When the request is an HTTP 1.1 request, the response is chunk encoded. When the request
is not an HTTP 1.1 request, the response would not contain the Content-Length
.
You always need to read the entire response body to check if the copy succeeds.
If the copy is successful, you receive a response with information about the copied object.
A copy request might return an error when Amazon S3 receives the copy request or while
Amazon S3 is copying the files. A 200 OK
response can contain either a success
or an error.
If the error occurs before the copy action starts, you receive a standard Amazon S3 error.
If the error occurs during the copy operation, the error response is embedded in the
200 OK
response. For example, in a cross-region copy, you may encounter throttling
and receive a 200 OK
response. For more information, see Resolve
the Error 200 response when copying objects to Amazon S3. The 200 OK
status
code means the copy was accepted, but it doesn't mean the copy is complete. Another
example is when you disconnect from Amazon S3 before the copy is complete, Amazon
S3 might cancel the copy and you may receive a 200 OK
response. You must stay
connected to Amazon S3 until the entire response is successfully received and processed.
If you call this API operation directly, make sure to design your application to parse the content of the response and handle it appropriately. If you use Amazon Web Services SDKs, SDKs handle this condition. The SDKs detect the embedded error and apply error handling per your configuration settings (including automatically retrying the request as appropriate). If the condition persists, the SDKs throw an exception (or, for the SDKs that don't use exceptions, they return an error).
The copy request charge is based on the storage class and Region that you specify for the destination object. The request can also result in a data retrieval charge for the source if the source storage class bills for data retrieval. If the copy source is in a different region, the data transfer is billed to the copy source account. For pricing information, see Amazon S3 pricing.
Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com
.

This example shows how to copy an object from one bucket/key to a different bucket/key.
// Create a client AmazonS3Client client = new AmazonS3Client(); // Create a CopyObject request CopyObjectRequest request = new CopyObjectRequest { SourceBucket = "SampleBucket", SourceKey = "Item1", DestinationBucket = "AnotherBucket", DestinationKey = "Copy1", CannedACL = S3CannedACL.PublicRead }; // Issue request client.CopyObject(request);
