#replication_statusString (readonly)

Amazon S3 can return this header if your request involves a bucket that is either a source or destination in a replication rule.

In replication you have a source bucket on which you configure replication and destination bucket where Amazon S3 stores object replicas.

  • If requesting object from the source bucket — Amazon S3 will return the x-amz-replication-status header if object in your request is eligible for replication.

    For example, suppose in your replication configuration you specify object prefix \"TaxDocs\" requesting Amazon S3 to replicate objects with key prefix \"TaxDocs\". Then any objects you upload with this key name prefix, for example \"TaxDocs/document1.pdf\", is eligible for replication. For any object request with this key name prefix Amazon S3 will return the x-amz-replication-status header with value PENDING, COMPLETED or FAILED indicating object replication status.

  • If requesting object from the destination bucket — Amazon S3 will return the x-amz-replication-status header with value REPLICA if object in your request is a replica that Amazon S3 created.

#delete(options = {}) ⇒ Types::DeleteObjectOutput

Removes the null version (if there is one) of an object and inserts a delete marker, which becomes the latest version of the object. If there isn't a null version, Amazon S3 does not remove any objects.

To remove a specific version, you must be the bucket owner and you must use the version Id subresource. Using this subresource permanently deletes the version. If the object deleted is a delete marker, Amazon S3 sets the response header, x-amz-delete-marker, to true.

If the object you want to delete is in a bucket where the bucket versioning configurationis MFA Delete enabled, you must include the x-amz-mfa request header in the DELETE versionId request. Requests that include x-amz-mfa must use HTTPS.

For more information about MFA Delete, see Using MFA Delete. To see sample requests that use versioning, see Sample Request.

You can delete objects by explicitly calling the DELETE Object API or configure its lifecycle (PutBucketLifecycle) to enable Amazon S3 to remove them for you. If you want to block users or accounts from removing or deleting objects from your bucket you must deny them the s3:DeleteObject, s3:DeleteObjectVersion and s3:PutLifeCycleConfiguration actions.

The following operation is related to DeleteObject

Examples:

#exists?Boolean

Returns true if this Object exists. Returns false otherwise.

Returns:

  • (Boolean)

    Returns true if this Object exists. Returns false otherwise.

#get(options = {}) ⇒ Types::GetObjectOutput

Retrieves objects from Amazon S3. To use GET, you must have READ access to the object. If you grant READ access to the anonymous user, you can return the object without using an authorization header.

An Amazon S3 bucket has no directory hierarchy such as you would find in a typical computer file system. You can, however, create a logical hierarchy by using object key names that imply a folder structure. For example, instead of naming an object sample.jpg, you can name it photos/2006/February/sample.jpg.

To get an object from such a logical hierarchy, specify the full key name for the object in the GET operation. For a virtual hosted-style request example, if you have the object photos/2006/February/sample.jpg, specify the resource as /photos/2006/February/sample.jpg. For a path-style request example, if you have the object photos/2006/February/sample.jpg in the bucket named examplebucket, specify the resource as /examplebucket/photos/2006/February/sample.jpg. For more information about request types, see HTTP Host Header Bucket Specification.

To distribute large files to many people, you can save bandwidth costs by using BitTorrent. For more information, see Amazon S3 Torrent. For more information about returning the ACL of an object, see GetObjectAcl.

If the object you are retrieving is stored in the GLACIER or DEEP_ARCHIVE storage classes, before you can retrieve the object you must first restore a copy using . Otherwise, this operation returns an InvalidObjectStateError error. For information about restoring archived objects, see Restoring Archived Objects.

Encryption request headers, like x-amz-server-side-encryption, should not be sent for GET requests if your object uses server-side encryption with CMKs stored in AWS KMS (SSE-KMS) or server-side encryption with Amazon S3–managed encryption keys (SSE-S3). If your object does use these types of keys, you’ll get an HTTP 400 BadRequest error.

If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you GET the object, you must use the following headers:

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

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

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

For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys).

Assuming you have permission to read object tags (permission for the s3:GetObjectVersionTagging action), the response also returns the x-amz-tagging-count header that provides the count of number of tags associated with the object. You can use GetObjectTagging to retrieve the tag set associated with an object.

Permissions

You need the s3:GetObject permission for this operation. For more information, see Specifying Permissions in a Policy. If the object you request does not exist, the error Amazon S3 returns depends on whether you also have the s3:ListBucket permission.

  • If you have the s3:ListBucket permission on the bucket, Amazon S3 will return an HTTP status code 404 ("no such key") error.

  • If you don’t have the s3:ListBucket permission, Amazon S3 will return an HTTP status code 403 ("access denied") error.

Versioning

By default, the GET operation returns the current version of an object. To return a different version, use the versionId subresource.

If the current version of the object is a delete marker, Amazon S3 behaves as if the object was deleted and includes x-amz-delete-marker: true in the response.

For more information about versioning, see PutBucketVersioning.

Overriding Response Header Values

There are times when you want to override certain response header values in a GET response. For example, you might override the Content-Disposition response header value in your GET request.

You can override values for a set of response headers using the following query parameters. These response header values are sent only on a successful request, that is, when status code 200 OK is returned. The set of headers you can override using these parameters is a subset of the headers that Amazon S3 accepts when you create an object. The response headers that you can override for the GET response are Content-Type, Content-Language, Expires, Cache-Control, Content-Disposition, and Content-Encoding. To override these header values in the GET response, you use the following request parameters.

You must sign the request, either using an Authorization header or a presigned URL, when using these parameters. They cannot be used with an unsigned (anonymous) request.

  • response-content-type

  • response-content-language

  • response-expires

  • response-cache-control

  • response-content-disposition

  • response-content-encoding

Additional Considerations about Request Headers

If both of the If-Match and If-Unmodified-Since headers are present in the request as follows: If-Match condition evaluates to true, and; If-Unmodified-Since condition evaluates to false; then, S3 returns 200 OK and the data requested.

If both of the If-None-Match and If-Modified-Since headers are present in the request as follows: If-None-Match condition evaluates to false, and; If-Modified-Since condition evaluates to true; then, S3 returns 304 Not Modified response code.

For more information about conditional requests, see RFC 7232.

#put(options = {}) ⇒ Types::PutObjectOutput

Adds an object to a bucket. You must have WRITE permissions on a bucket to add an object to it.

Amazon S3 never adds partial objects; if you receive a success response, Amazon S3 added the entire object to the bucket.

Amazon S3 is a distributed system. If it receives multiple write requests for the same object simultaneously, it overwrites all but the last object written. Amazon S3 does not provide object locking; if you need this, make sure to build it into your application layer or use versioning instead.

To ensure that data is not corrupted traversing the network, use the Content-MD5 header. When you use this header, Amazon S3 checks the object against the provided MD5 value and, if they do not match, returns an error. Additionally, you can calculate the MD5 while putting an object to Amazon S3 and compare the returned ETag to the calculated MD5 value.

To configure your application to send the request headers before sending the request body, use the 100-continue HTTP status code. For PUT operations, this helps you avoid sending the message body if the message is rejected based on the headers (for example, because authentication fails or a redirect occurs). For more information on the 100-continue HTTP status code, see Section 8.2.3 of http://www.ietf.org/rfc/rfc2616.txt.

You can optionally request server-side encryption. With server-side encryption, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts the data when you access it. You have the option to provide your own encryption key or use AWS-managed encryption keys. For more information, see Using Server-Side Encryption.

Access Permissions

You can optionally specify the accounts or groups that should be granted specific permissions on the new object. There are two ways to grant the permissions using the request headers:

  • Specify a canned ACL with the x-amz-acl request header. For more information, see Canned ACL.

  • Specify access permissions explicitly with the x-amz-grant-read, x-amz-grant-read-acp, x-amz-grant-write-acp, and x-amz-grant-full-control headers. These parameters map to the set of permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview.

You can use either a canned ACL or specify access permissions explicitly. You cannot do both.

Server-Side- Encryption-Specific Request Headers

You can optionally tell Amazon S3 to encrypt data at rest using server-side encryption. Server-side encryption is for data encryption at rest. Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it when you access it. The option you use depends on whether you want to use AWS-managed encryption keys or provide your own encryption key.

  • Use encryption keys managed Amazon S3 or customer master keys (CMKs) stored in AWS Key Management Service (KMS) – If you want AWS to manage the keys used to encrypt data, specify the following headers in the request.

    • x-amz-server-side​-encryption

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

    • x-amz-server-side-encryption-context

    If you specify x-amz-server-side-encryption:aws:kms, but don't provide x-amz-server-side- encryption-aws-kms-key-id, Amazon S3 uses the AWS managed CMK in AWS KMS to protect the data.

    All GET and PUT requests for an object protected by AWS KMS fail if you don't make them with SSL or by using SigV4.

    For more information on Server-Side Encryption with CMKs stored in AWS KMS (SSE-KMS), see Protecting Data Using Server-Side Encryption with CMKs stored in AWS.

  • Use customer-provided encryption keys – If you want to manage your own encryption keys, provide all the following headers in the request.

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

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

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

    For more information on Server-Side Encryption with CMKs stored in KMS (SSE-KMS), see Protecting Data Using Server-Side Encryption with CMKs stored in AWS KMS.

Access-Control-List (ACL)-Specific Request Headers

You also can use the following access control–related headers with this operation. By default, all objects are private. Only the owner has full access control. When adding a new object, you can grant permissions to individual AWS accounts or to predefined groups defined by Amazon S3. These permissions are then added to the Access Control List (ACL) on the object. For more information, see Using ACLs. With this operation, you can grant access permissions using one of the following two methods:

  • Specify a canned ACL (x-amz-acl) — Amazon S3 supports a set of predefined ACLs, known as canned ACLs. Each canned ACL has a predefined set of grantees and permissions. For more information, see Canned ACL.

  • Specify access permissions explicitly — To explicitly grant access permissions to specific AWS accounts or groups, use the following headers. Each header maps to specific permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview. In the header, you specify a list of grantees who get the specific permission. To grant permissions explicitly use:

    • x-amz-grant-read

    • x-amz-grant-write

    • x-amz-grant-read-acp

    • x-amz-grant-write-acp

    • x-amz-grant-full-control

    You specify each grantee as a type=value pair, where the type is one of the following:

    • emailAddress – if the value specified is the email address of an AWS account

      Using email addresses to specify a grantee is only supported in the following AWS Regions:

      • US East (N. Virginia)

      • US West (N. California)

      • US West (Oregon)

      • Asia Pacific (Singapore)

      • Asia Pacific (Sydney)

      • Asia Pacific (Tokyo)

      • EU (Ireland)

      • South America (São Paulo)

      For a list of all the Amazon S3 supported regions and endpoints, see Regions and Endpoints in the AWS General Reference

    • id – if the value specified is the canonical user ID of an AWS account

    • uri – if you are granting permissions to a predefined group

    For example, the following x-amz-grant-read header grants the AWS accounts identified by email addresses permissions to read object data and its metadata:

    x-amz-grant-read: emailAddress="xyz@amazon.com", emailAddress="abc@amazon.com"

Server-Side- Encryption-Specific Request Headers

You can optionally tell Amazon S3 to encrypt data at rest using server-side encryption. Server-side encryption is for data encryption at rest. Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it when you access it. The option you use depends on whether you want to use AWS-managed encryption keys or provide your own encryption key.

  • Use encryption keys managed by Amazon S3 or customer master keys (CMKs) stored in AWS Key Management Service (KMS) – If you want AWS to manage the keys used to encrypt data, specify the following headers in the request.

    • x-amz-server-side​-encryption

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

    • x-amz-server-side-encryption-context

    If you specify x-amz-server-side-encryption:aws:kms, but don't provide x-amz-server-side- encryption-aws-kms-key-id, Amazon S3 uses the default AWS KMS CMK to protect the data.

    All GET and PUT requests for an object protected by AWS KMS fail if you don't make them with SSL or by using SigV4.

    For more information on Server-Side Encryption with CMKs stored in AWS KMS (SSE-KMS), see Protecting Data Using Server-Side Encryption with CMKs stored in AWS KMS.

  • Use customer-provided encryption keys – If you want to manage your own encryption keys, provide all the following headers in the request.

    If you use this feature, the ETag value that Amazon S3 returns in the response is not the MD5 of the object.

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

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

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

    For more information on Server-Side Encryption with CMKs stored in AWS KMS (SSE-KMS), see Protecting Data Using Server-Side Encryption with CMKs stored in AWS KMS.

Storage Class Options

By default, Amazon S3 uses the Standard storage class to store newly created objects. The Standard storage class provides high durability and high availability. You can specify other storage classes depending on the performance needs. For more information, see Storage Classes in the Amazon Simple Storage Service Developer Guide.

Versioning

If you enable versioning for a bucket, Amazon S3 automatically generates a unique version ID for the object being stored. Amazon S3 returns this ID in the response using the x-amz-version-id response header. If versioning is suspended, Amazon S3 always uses null as the version ID for the object stored. For more information about returning the versioning state of a bucket, see GetBucketVersioning. If you enable versioning for a bucket, when Amazon S3 receives multiple write requests for the same object simultaneously, it stores all of the objects.

#restore_object(options = {}) ⇒ Types::RestoreObjectOutput

Restores an archived copy of an object back into Amazon S3

This operation performs the following types of requests:

  • select - Perform a select query on an archived object

  • restore an archive - Restore an archived object

To use this operation, you must have permissions to perform the s3:RestoreObject and s3:GetObject actions. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources in the Amazon Simple Storage Service Developer Guide.

Querying Archives with Select Requests

You use a select type of request to perform SQL queries on archived objects. The archived objects that are being queried by the select request must be formatted as uncompressed comma-separated values (CSV) files. You can run queries and custom analytics on your archived data without having to restore your data to a hotter Amazon S3 tier. For an overview about select requests, see Querying Archived Objects in the Amazon Simple Storage Service Developer Guide.

When making a select request, do the following:

  • Define an output location for the select query's output. This must be an Amazon S3 bucket in the same AWS Region as the bucket that contains the archive object that is being queried. The AWS account that initiates the job must have permissions to write to the S3 bucket. You can specify the storage class and encryption for the output objects stored in the bucket. For more information about output, see Querying Archived Objects in the Amazon Simple Storage Service Developer Guide.

    For more information about the S3 structure in the request body, see the following:

  • Define the SQL expression for the SELECT type of restoration for your query in the request body's SelectParameters structure. You can use expressions like the following examples.

    • The following expression returns all records from the specified object.

      SELECT * FROM Object

    • Assuming that you are not using any headers for data stored in the object, you can specify columns with positional headers.

      SELECT s.1, s.2 FROM Object s WHERE s._3 > 100

    • If you have headers and you set the fileHeaderInfo in the CSV structure in the request body to USE, you can specify headers in the query. (If you set the fileHeaderInfo field to IGNORE, the first row is skipped for the query.) You cannot mix ordinal positions with header column names.

      SELECT s.Id, s.FirstName, s.SSN FROM S3Object s

For more information about using SQL with Glacier Select restore, see SQL Reference for Amazon S3 Select and Glacier Select in the Amazon Simple Storage Service Developer Guide.

When making a select request, you can also do the following:

  • To expedite your queries, specify the Expedited tier. For more information about tiers, see "Restoring Archives," later in this topic.

  • Specify details about the data serialization format of both the input object that is being queried and the serialization of the CSV-encoded query results.

The following are additional important facts about the select feature:

  • The output results are new Amazon S3 objects. Unlike archive retrievals, they are stored until explicitly deleted-manually or through a lifecycle policy.

  • You can issue more than one select request on the same Amazon S3 object. Amazon S3 doesn't deduplicate requests, so avoid issuing duplicate requests.

  • Amazon S3 accepts a select request even if the object has already been restored. A select request doesn’t return error response 409.

Restoring Archives

Objects in the GLACIER and DEEP_ARCHIVE storage classes are archived. To access an archived object, you must first initiate a restore request. This restores a temporary copy of the archived object. In a restore request, you specify the number of days that you want the restored copy to exist. After the specified period, Amazon S3 deletes the temporary copy but the object remains archived in the GLACIER or DEEP_ARCHIVE storage class that object was restored from.

To restore a specific object version, you can provide a version ID. If you don't provide a version ID, Amazon S3 restores the current version.

The time it takes restore jobs to finish depends on which storage class the object is being restored from and which data access tier you specify.

When restoring an archived object (or using a select request), you can specify one of the following data access tier options in the Tier element of the request body:

  • Expedited - Expedited retrievals allow you to quickly access your data stored in the GLACIER storage class when occasional urgent requests for a subset of archives are required. For all but the largest archived objects (250 MB+), data accessed using Expedited retrievals are typically made available within 1–5 minutes. Provisioned capacity ensures that retrieval capacity for Expedited retrievals is available when you need it. Expedited retrievals and provisioned capacity are not available for the DEEP_ARCHIVE storage class.

  • Standard - Standard retrievals allow you to access any of your archived objects within several hours. This is the default option for the GLACIER and DEEP_ARCHIVE retrieval requests that do not specify the retrieval option. Standard retrievals typically complete within 3-5 hours from the GLACIER storage class and typically complete within 12 hours from the DEEP_ARCHIVE storage class.

  • Bulk - Bulk retrievals are Amazon Glacier’s lowest-cost retrieval option, enabling you to retrieve large amounts, even petabytes, of data inexpensively in a day. Bulk retrievals typically complete within 5-12 hours from the GLACIER storage class and typically complete within 48 hours from the DEEP_ARCHIVE storage class.

For more information about archive retrieval options and provisioned capacity for Expedited data access, see Restoring Archived Objects in the Amazon Simple Storage Service Developer Guide.

You can use Amazon S3 restore speed upgrade to change the restore speed to a faster speed while it is in progress. You upgrade the speed of an in-progress restoration by issuing another restore request to the same object, setting a new Tier request element. When issuing a request to upgrade the restore tier, you must choose a tier that is faster than the tier that the in-progress restore is using. You must not change any other parameters, such as the Days request element. For more information, see Upgrading the Speed of an In-Progress Restore in the Amazon Simple Storage Service Developer Guide.

To get the status of object restoration, you can send a HEAD request. Operations return the x-amz-restore header, which provides information about the restoration status, in the response. You can use Amazon S3 event notifications to notify you when a restore is initiated or completed. For more information, see Configuring Amazon S3 Event Notifications in the Amazon Simple Storage Service Developer Guide.

After restoring an archived object, you can update the restoration period by reissuing the request with a new period. Amazon S3 updates the restoration period relative to the current time and charges only for the request-there are no data transfer charges. You cannot update the restoration period when Amazon S3 is actively processing your current restore request for the object.

If your bucket has a lifecycle configuration with a rule that includes an expiration action, the object expiration overrides the life span that you specify in a restore request. For example, if you restore an object copy for 10 days, but the object is scheduled to expire in 3 days, Amazon S3 deletes the object in 3 days. For more information about lifecycle configuration, see PutBucketLifecycleConfiguration and Object Lifecycle Management in Amazon Simple Storage Service Developer Guide.

Responses

A successful operation returns either the 200 OK or 202 Accepted status code.

  • If the object copy is not previously restored, then Amazon S3 returns 202 Accepted in the response.

  • If the object copy is previously restored, Amazon S3 returns 200 OK in the response.

Special Errors

    • Code: RestoreAlreadyInProgress

    • Cause: Object restore is already in progress. (This error does not apply to SELECT type requests.)

    • HTTP Status Code: 409 Conflict

    • SOAP Fault Code Prefix: Client

    • Code: GlacierExpeditedRetrievalNotAvailable

    • Cause: Glacier expedited retrievals are currently not available. Try again later. (Returned if there is insufficient capacity to process the Expedited request. This error applies only to Expedited retrievals and not to Standard or Bulk retrievals.)

    • HTTP Status Code: 503

    • SOAP Fault Code Prefix: N/A
