CopyObject - Amazon Simple Storage Service
Request SyntaxURI Request ParametersRequest BodyResponse SyntaxResponse ElementsErrorsExamplesSee Also

CopyObject

Creates a copy of an object that is already stored in Amazon S3.

Note

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.

Note

  • 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-zone-id.region-code.amazonaws.com/key-name . Path-style requests are not supported. For more information about endpoints in Availability Zones, see Regional and Zonal endpoints for directory buckets in Availability Zones in the Amazon S3 User Guide. For more information about endpoints in Local Zones, see Available Local Zone for directory buckets 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 AWS 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 AWS Account Management Guide.

Important

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.

Authentication and authorization

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.

AWS CLI or SDKs handles authentication and authorization on your behalf.

Permissions

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.

    If the object is encrypted with SSE-KMS, you must also have the kms:GenerateDataKey and kms:Decrypt permissions in IAM identity-based policies and AWS KMS key policies for the AWS KMS key.

    For example policies, see Example bucket policies for S3 Express One Zone and AWS Identity and Access Management (IAM) identity-based policies for S3 Express One Zone in the Amazon S3 User Guide.

Response and special errors

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 AWS 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).

Charge

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.

URI Request Parameters

The request uses the following URI parameters.

Bucket

The name of the destination bucket.

Directory buckets - When you use this operation with a directory bucket, you must use virtual-hosted-style requests in the format Bucket-name.s3express-zone-id.region-code.amazonaws.com. Path-style requests are not supported. Directory bucket names must be unique in the chosen Zone (Availability Zone or Local Zone). Bucket names must follow the format bucket-base-name--zone-id--x-s3 (for example, DOC-EXAMPLE-BUCKET--usw2-az1--x-s3). For information about bucket naming restrictions, see Directory bucket naming rules in the Amazon S3 User Guide.

Note

Copying objects across different AWS Regions isn't supported when the source or destination bucket is in AWS Local Zones. The source and destination buckets must have the same parent AWS Region. Otherwise, you get an HTTP 400 Bad Request error with the error code InvalidRequest.

Access points - When you use this action with an access point, you must provide the alias of the access point in place of the bucket name or specify the access point ARN. When using the access point ARN, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.Region.amazonaws.com. When using this action with an access point through the AWS SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide.

Note

Access points and Object Lambda access points are not supported by directory buckets.

S3 on Outposts - When you use this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com. When you use this action with S3 on Outposts through the AWS SDKs, you provide the Outposts access point ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see What is S3 on Outposts? in the Amazon S3 User Guide.

Required: Yes

Cache-Control

Specifies the caching behavior along the request/reply chain.

Content-Disposition

Specifies presentational information for the object. Indicates whether an object should be displayed in a web browser or downloaded as a file. It allows specifying the desired filename for the downloaded file.

Content-Encoding

Specifies what content encodings have been applied to the object and thus what decoding mechanisms must be applied to obtain the media-type referenced by the Content-Type header field.

Note

For directory buckets, only the aws-chunked value is supported in this header field.

Content-Language

The language the content is in.

Content-Type

A standard MIME type that describes the format of the object data.

Expires

The date and time at which the object is no longer cacheable.

Key

The key of the destination object.

Length Constraints: Minimum length of 1.

Required: Yes

x-amz-acl

The canned access control list (ACL) to apply to the object.

When you copy an object, the ACL metadata is not preserved and is set to private by default. Only the owner has full access control. To override the default ACL setting, specify a new ACL when you generate a copy request. For more information, see Using ACLs.

If the destination bucket that you're copying objects to uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. Buckets that use this setting only accept PUT requests that don't specify an ACL or PUT requests that specify bucket owner full control ACLs, such as the bucket-owner-full-control canned ACL or an equivalent form of this ACL expressed in the XML format. For more information, see Controlling ownership of objects and disabling ACLs in the Amazon S3 User Guide.

Note

  • If your destination bucket uses the bucket owner enforced setting for Object Ownership, all objects written to the bucket by any account will be owned by the bucket owner.

  • This functionality is not supported for directory buckets.

  • This functionality is not supported for Amazon S3 on Outposts.

Valid Values: private | public-read | public-read-write | authenticated-read | aws-exec-read | bucket-owner-read | bucket-owner-full-control

x-amz-checksum-algorithm

Indicates the algorithm that you want Amazon S3 to use to create the checksum for the object. For more information, see Checking object integrity in the Amazon S3 User Guide.

When you copy an object, if the source object has a checksum, that checksum value will be copied to the new object by default. If the CopyObject request does not include this x-amz-checksum-algorithm header, the checksum algorithm will be copied from the source object to the destination object (if it's present on the source object). You can optionally specify a different checksum algorithm to use with the x-amz-checksum-algorithm header. Unrecognized or unsupported values will respond with the HTTP status code 400 Bad Request.

Note

For directory buckets, when you use AWS SDKs, CRC32 is the default checksum algorithm that's used for performance.

Valid Values: CRC32 | CRC32C | SHA1 | SHA256

x-amz-copy-source

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.

    Note

    • Amazon S3 supports copy operations using Access points only when the source and destination buckets are in the same AWS 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.

Note

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

Pattern: \/.+\/.+

Required: Yes

x-amz-copy-source-if-match

Copies the object if its entity tag (ETag) matches the specified tag.

If both the x-amz-copy-source-if-match and x-amz-copy-source-if-unmodified-since headers are present in the request and evaluate as follows, Amazon S3 returns 200 OK and copies the data:

  • x-amz-copy-source-if-match condition evaluates to true

  • x-amz-copy-source-if-unmodified-since condition evaluates to false

x-amz-copy-source-if-modified-since

Copies the object if it has been modified since the specified time.

If both the x-amz-copy-source-if-none-match and x-amz-copy-source-if-modified-since headers are present in the request and evaluate as follows, Amazon S3 returns the 412 Precondition Failed response code:

  • x-amz-copy-source-if-none-match condition evaluates to false

  • x-amz-copy-source-if-modified-since condition evaluates to true

x-amz-copy-source-if-none-match

Copies the object if its entity tag (ETag) is different than the specified ETag.

If both the x-amz-copy-source-if-none-match and x-amz-copy-source-if-modified-since headers are present in the request and evaluate as follows, Amazon S3 returns the 412 Precondition Failed response code:

  • x-amz-copy-source-if-none-match condition evaluates to false

  • x-amz-copy-source-if-modified-since condition evaluates to true

x-amz-copy-source-if-unmodified-since

Copies the object if it hasn't been modified since the specified time.

If both the x-amz-copy-source-if-match and x-amz-copy-source-if-unmodified-since headers are present in the request and evaluate as follows, Amazon S3 returns 200 OK and copies the data:

  • x-amz-copy-source-if-match condition evaluates to true

  • x-amz-copy-source-if-unmodified-since condition evaluates to false

x-amz-copy-source-server-side-encryption-customer-algorithm

Specifies the algorithm to use when decrypting the source object (for example, AES256).

If the source object for the copy is stored in Amazon S3 using SSE-C, you must provide the necessary encryption information in your request so that Amazon S3 can decrypt the object for copying.

Note

This functionality is not supported when the source object is in a directory bucket.

x-amz-copy-source-server-side-encryption-customer-key

Specifies the customer-provided encryption key for Amazon S3 to use to decrypt the source object. The encryption key provided in this header must be the same one that was used when the source object was created.

If the source object for the copy is stored in Amazon S3 using SSE-C, you must provide the necessary encryption information in your request so that Amazon S3 can decrypt the object for copying.

Note

This functionality is not supported when the source object is in a directory bucket.

x-amz-copy-source-server-side-encryption-customer-key-MD5

Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

If the source object for the copy is stored in Amazon S3 using SSE-C, you must provide the necessary encryption information in your request so that Amazon S3 can decrypt the object for copying.

Note

This functionality is not supported when the source object is in a directory bucket.

x-amz-expected-bucket-owner

The account ID of the expected destination bucket owner. If the account ID that you provide does not match the actual owner of the destination bucket, the request fails with the HTTP status code 403 Forbidden (access denied).

x-amz-grant-full-control

Gives the grantee READ, READ_ACP, and WRITE_ACP permissions on the object.

Note

  • This functionality is not supported for directory buckets.

  • This functionality is not supported for Amazon S3 on Outposts.

x-amz-grant-read

Allows grantee to read the object data and its metadata.

Note

  • This functionality is not supported for directory buckets.

  • This functionality is not supported for Amazon S3 on Outposts.

x-amz-grant-read-acp

Allows grantee to read the object ACL.

Note

  • This functionality is not supported for directory buckets.

  • This functionality is not supported for Amazon S3 on Outposts.

x-amz-grant-write-acp

Allows grantee to write the ACL for the applicable object.

Note

  • This functionality is not supported for directory buckets.

  • This functionality is not supported for Amazon S3 on Outposts.

x-amz-metadata-directive

Specifies whether the metadata is copied from the source object or replaced with metadata that's provided in the request. When copying an object, you can preserve all metadata (the default) or specify new metadata. If this header isn’t specified, COPY is the default behavior.

General purpose bucket - For general purpose buckets, when you grant permissions, you can use the s3:x-amz-metadata-directive condition key to enforce certain metadata behavior when objects are uploaded. For more information, see Amazon S3 condition key examples in the Amazon S3 User Guide.

Note

x-amz-website-redirect-location is unique to each object and is not copied when using the x-amz-metadata-directive header. To copy the value, you must specify x-amz-website-redirect-location in the request header.

Valid Values: COPY | REPLACE

x-amz-object-lock-legal-hold

Specifies whether you want to apply a legal hold to the object copy.

Note

This functionality is not supported for directory buckets.

Valid Values: ON | OFF

x-amz-object-lock-mode

The Object Lock mode that you want to apply to the object copy.

Note

This functionality is not supported for directory buckets.

Valid Values: GOVERNANCE | COMPLIANCE

x-amz-object-lock-retain-until-date

The date and time when you want the Object Lock of the object copy to expire.

Note

This functionality is not supported for directory buckets.

x-amz-request-payer

Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. If either the source or destination S3 bucket has Requester Pays enabled, the requester will pay for corresponding charges to copy the object. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide.

Note

This functionality is not supported for directory buckets.

Valid Values: requester

x-amz-server-side-encryption

The server-side encryption algorithm used when storing this object in Amazon S3. Unrecognized or unsupported values won’t write a destination object and will receive a 400 Bad Request response.

Amazon S3 automatically encrypts all new objects that are copied to an S3 bucket. When copying an object, if you don't specify encryption information in your copy request, the encryption setting of the target object is set to the default encryption configuration of the destination bucket. By default, all buckets have a base level of encryption configuration that uses server-side encryption with Amazon S3 managed keys (SSE-S3). If the destination bucket has a different default encryption configuration, Amazon S3 uses the corresponding encryption key to encrypt the target object copy.

With server-side encryption, Amazon S3 encrypts your data as it writes your data to disks in its data centers and decrypts the data when you access it. For more information about server-side encryption, see Using Server-Side Encryption in the Amazon S3 User Guide.

General purpose buckets

  • For general purpose buckets, there are the following supported options for server-side encryption: server-side encryption with AWS Key Management Service (AWS KMS) keys (SSE-KMS), dual-layer server-side encryption with AWS KMS keys (DSSE-KMS), and server-side encryption with customer-provided encryption keys (SSE-C). Amazon S3 uses the corresponding KMS key, or a customer-provided key to encrypt the target object copy.

  • When you perform a CopyObject operation, if you want to use a different type of encryption setting for the target object, you can specify appropriate encryption-related headers to encrypt the target object with an Amazon S3 managed key, a KMS key, or a customer-provided key. If the encryption setting in your request is different from the default encryption configuration of the destination bucket, the encryption setting in your request takes precedence.

Directory buckets

  • For directory buckets, there are only two supported options for server-side encryption: server-side encryption with Amazon S3 managed keys (SSE-S3) (AES256) and server-side encryption with AWS KMS keys (SSE-KMS) (aws:kms). We recommend that the bucket's default encryption uses the desired encryption configuration and you don't override the bucket default encryption in your CreateSession requests or PUT object requests. Then, new objects are automatically encrypted with the desired encryption settings. For more information, see Protecting data with server-side encryption in the Amazon S3 User Guide. For more information about the encryption overriding behaviors in directory buckets, see Specifying server-side encryption with AWS KMS for new object uploads.

  • To encrypt new object copies to a directory bucket with SSE-KMS, we recommend you specify SSE-KMS as the directory bucket's default encryption configuration with a KMS key (specifically, a customer managed key). The AWS managed key (aws/s3) isn't supported. Your SSE-KMS configuration can only support 1 customer managed key per directory bucket for the lifetime of the bucket. After you specify a customer managed key for SSE-KMS, you can't override the customer managed key for the bucket's SSE-KMS configuration. Then, when you perform a CopyObject operation and want to specify server-side encryption settings for new object copies with SSE-KMS in the encryption-related request headers, you must ensure the encryption key is the same customer managed key that you specified for the directory bucket's default encryption configuration.

Valid Values: AES256 | aws:kms | aws:kms:dsse

x-amz-server-side-encryption-aws-kms-key-id

Specifies the AWS KMS key ID (Key ID, Key ARN, or Key Alias) to use for object encryption. All GET and PUT requests for an object protected by AWS KMS will fail if they're not made via SSL or using SigV4. For information about configuring any of the officially supported AWS SDKs and AWS CLI, see Specifying the Signature Version in Request Authentication in the Amazon S3 User Guide.

Directory buckets - If you specify x-amz-server-side-encryption with aws:kms, the x-amz-server-side-encryption-aws-kms-key-id header is implicitly assigned the ID of the AWS KMS symmetric encryption customer managed key that's configured for your directory bucket's default encryption setting. If you want to specify the x-amz-server-side-encryption-aws-kms-key-id header explicitly, you can only specify it with the ID (Key ID or Key ARN) of the AWS KMS customer managed key that's configured for your directory bucket's default encryption setting. Otherwise, you get an HTTP 400 Bad Request error. Only use the key ID or key ARN. The key alias format of the KMS key isn't supported. Your SSE-KMS configuration can only support 1 customer managed key per directory bucket for the lifetime of the bucket. The AWS managed key (aws/s3) isn't supported.

x-amz-server-side-encryption-bucket-key-enabled

Specifies whether Amazon S3 should use an S3 Bucket Key for object encryption with server-side encryption using AWS Key Management Service (AWS KMS) keys (SSE-KMS). If a target object uses SSE-KMS, you can enable an S3 Bucket Key for the object.

Setting this header to true causes Amazon S3 to use an S3 Bucket Key for object encryption with SSE-KMS. Specifying this header with a COPY action doesn’t affect bucket-level settings for S3 Bucket Key.

For more information, see Amazon S3 Bucket Keys in the Amazon S3 User Guide.

Note

Directory buckets - S3 Bucket Keys aren't supported, when you copy SSE-KMS encrypted objects from general purpose buckets to directory buckets, from directory buckets to general purpose buckets, or between directory buckets, through CopyObject. In this case, Amazon S3 makes a call to AWS KMS every time a copy request is made for a KMS-encrypted object.

x-amz-server-side-encryption-context

Specifies the AWS KMS Encryption Context as an additional encryption context to use for the destination object encryption. The value of this header is a base64-encoded UTF-8 string holding JSON with the encryption context key-value pairs.

General purpose buckets - This value must be explicitly added to specify encryption context for CopyObject requests if you want an additional encryption context for your destination object. The additional encryption context of the source object won't be copied to the destination object. For more information, see Encryption context in the Amazon S3 User Guide.

Directory buckets - You can optionally provide an explicit encryption context value. The value must match the default encryption context - the bucket Amazon Resource Name (ARN). An additional encryption context value is not supported.

x-amz-server-side-encryption-customer-algorithm

Specifies the algorithm to use when encrypting the object (for example, AES256).

When you perform a CopyObject operation, if you want to use a different type of encryption setting for the target object, you can specify appropriate encryption-related headers to encrypt the target object with an Amazon S3 managed key, a KMS key, or a customer-provided key. If the encryption setting in your request is different from the default encryption configuration of the destination bucket, the encryption setting in your request takes precedence.

Note

This functionality is not supported when the destination bucket is a directory bucket.

x-amz-server-side-encryption-customer-key

Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded. Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side-encryption-customer-algorithm header.

Note

This functionality is not supported when the destination bucket is a directory bucket.

x-amz-server-side-encryption-customer-key-MD5

Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

Note

This functionality is not supported when the destination bucket is a directory bucket.

x-amz-source-expected-bucket-owner

The account ID of the expected source bucket owner. If the account ID that you provide does not match the actual owner of the source bucket, the request fails with the HTTP status code 403 Forbidden (access denied).

x-amz-storage-class

If the x-amz-storage-class header is not used, the copied object will be stored in the STANDARD Storage Class by default. The STANDARD storage class provides high durability and high availability. Depending on performance needs, you can specify a different Storage Class.

Note

  • Directory buckets - For directory buckets, only the S3 Express One Zone storage class is supported to store newly created objects. Unsupported storage class values won't write a destination object and will respond with the HTTP status code 400 Bad Request.

  • Amazon S3 on Outposts - S3 on Outposts only uses the OUTPOSTS Storage Class.

You can use the CopyObject action to change the storage class of an object that is already stored in Amazon S3 by using the x-amz-storage-class header. For more information, see Storage Classes in the Amazon S3 User Guide.

Before using an object as a source object for the copy operation, you must restore a copy of it if it meets any of the following conditions:

  • The storage class of the source object is GLACIER or DEEP_ARCHIVE.

  • The storage class of the source object is INTELLIGENT_TIERING and it's S3 Intelligent-Tiering access tier is Archive Access or Deep Archive Access.

For more information, see RestoreObject and Copying Objects in the Amazon S3 User Guide.

Valid Values: STANDARD | REDUCED_REDUNDANCY | STANDARD_IA | ONEZONE_IA | INTELLIGENT_TIERING | GLACIER | DEEP_ARCHIVE | OUTPOSTS | GLACIER_IR | SNOW | EXPRESS_ONEZONE

x-amz-tagging

The tag-set for the object copy in the destination bucket. This value must be used in conjunction with the x-amz-tagging-directive if you choose REPLACE for the x-amz-tagging-directive. If you choose COPY for the x-amz-tagging-directive, you don't need to set the x-amz-tagging header, because the tag-set will be copied from the source object directly. The tag-set must be encoded as URL Query parameters.

The default value is the empty value.

Note

Directory buckets - For directory buckets in a CopyObject operation, only the empty tag-set is supported. Any requests that attempt to write non-empty tags into directory buckets will receive a 501 Not Implemented status code. When the destination bucket is a directory bucket, you will receive a 501 Not Implemented response in any of the following situations:

  • When you attempt to COPY the tag-set from an S3 source object that has non-empty tags.

  • When you attempt to REPLACE the tag-set of a source object and set a non-empty value to x-amz-tagging.

  • When you don't set the x-amz-tagging-directive header and the source object has non-empty tags. This is because the default value of x-amz-tagging-directive is COPY.

Because only the empty tag-set is supported for directory buckets in a CopyObject operation, the following situations are allowed:

  • When you attempt to COPY the tag-set from a directory bucket source object that has no tags to a general purpose bucket. It copies an empty tag-set to the destination object.

  • When you attempt to REPLACE the tag-set of a directory bucket source object and set the x-amz-tagging value of the directory bucket destination object to empty.

  • When you attempt to REPLACE the tag-set of a general purpose bucket source object that has non-empty tags and set the x-amz-tagging value of the directory bucket destination object to empty.

  • When you attempt to REPLACE the tag-set of a directory bucket source object and don't set the x-amz-tagging value of the directory bucket destination object. This is because the default value of x-amz-tagging is the empty value.

x-amz-tagging-directive

Specifies whether the object tag-set is copied from the source object or replaced with the tag-set that's provided in the request.

The default value is COPY.

Note

Directory buckets - For directory buckets in a CopyObject operation, only the empty tag-set is supported. Any requests that attempt to write non-empty tags into directory buckets will receive a 501 Not Implemented status code. When the destination bucket is a directory bucket, you will receive a 501 Not Implemented response in any of the following situations:

  • When you attempt to COPY the tag-set from an S3 source object that has non-empty tags.

  • When you attempt to REPLACE the tag-set of a source object and set a non-empty value to x-amz-tagging.

  • When you don't set the x-amz-tagging-directive header and the source object has non-empty tags. This is because the default value of x-amz-tagging-directive is COPY.

Because only the empty tag-set is supported for directory buckets in a CopyObject operation, the following situations are allowed:

  • When you attempt to COPY the tag-set from a directory bucket source object that has no tags to a general purpose bucket. It copies an empty tag-set to the destination object.

  • When you attempt to REPLACE the tag-set of a directory bucket source object and set the x-amz-tagging value of the directory bucket destination object to empty.

  • When you attempt to REPLACE the tag-set of a general purpose bucket source object that has non-empty tags and set the x-amz-tagging value of the directory bucket destination object to empty.

  • When you attempt to REPLACE the tag-set of a directory bucket source object and don't set the x-amz-tagging value of the directory bucket destination object. This is because the default value of x-amz-tagging is the empty value.

Valid Values: COPY | REPLACE

x-amz-website-redirect-location

If the destination bucket is configured as a website, redirects requests for this object copy to another object in the same bucket or to an external URL. Amazon S3 stores the value of this header in the object metadata. This value is unique to each object and is not copied when using the x-amz-metadata-directive header. Instead, you may opt to provide this header in combination with the x-amz-metadata-directive header.

Note

This functionality is not supported for directory buckets.
