Restores an archived copy of an object back into Amazon S3
This functionality is not supported for Amazon S3 on Outposts.
This action performs the following types of requests:
select - Perform a select query on an archived object
restore an archive - Restore an archived object
For more information about the
S3 structure in the request body, see the following:
Managing Access with ACLs in the Amazon S3 User Guide
Protecting Data Using Server-Side Encryption in the Amazon S3 User Guide
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
in the request body to
USE, you can specify headers in the query. (If you set
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
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 configuration.
You can issue more than one select request on the same Amazon S3 object. Amazon S3 doesn't duplicate 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
To use this operation, you must have permissions to perform the
action. 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 S3 User Guide.
Objects that you archive to the S3 Glacier Flexible Retrieval Flexible Retrieval or S3 Glacier Deep Archive storage class, and S3 Intelligent-Tiering Archive or S3 Intelligent-Tiering Deep Archive tiers, are not accessible in real time. For objects in the S3 Glacier Flexible Retrieval Flexible Retrieval or S3 Glacier Deep Archive storage classes, you must first initiate a restore request, and then wait until a temporary copy of the object is available. If you want a permanent copy of the object, create a copy of it in the Amazon S3 Standard storage class in your S3 bucket. To access an archived object, you must restore the object for the duration (number of days) that you specify. For objects in the Archive Access or Deep Archive Access tiers of S3 Intelligent-Tiering, you must first initiate a restore request, and then wait until the object is moved into the Frequent Access tier.
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.
When restoring an archived object, 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 S3 Glacier Flexible Retrieval Flexible Retrieval storage class or S3 Intelligent-Tiering
Archive tier when occasional urgent requests for restoring archives are required.
For all but the largest archived objects (250 MB+), data accessed using Expedited
retrievals is 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 objects stored in the S3
Glacier Deep Archive storage class or S3 Intelligent-Tiering Deep Archive tier.
Standard - Standard retrievals allow you to access any of your archived objects
within several hours. This is the default option for retrieval requests that do not
specify the retrieval option. Standard retrievals typically finish within 3–5 hours
for objects stored in the S3 Glacier Flexible Retrieval Flexible Retrieval storage
class or S3 Intelligent-Tiering Archive tier. They typically finish within 12 hours
for objects stored in the S3 Glacier Deep Archive storage class or S3 Intelligent-Tiering
Deep Archive tier. Standard retrievals are free for objects stored in S3 Intelligent-Tiering.
Bulk - Bulk retrievals free for objects stored in the S3 Glacier Flexible
Retrieval and S3 Intelligent-Tiering storage classes, enabling you to retrieve large
amounts, even petabytes, of data at no cost. Bulk retrievals typically finish within
5–12 hours for objects stored in the S3 Glacier Flexible Retrieval Flexible Retrieval
storage class or S3 Intelligent-Tiering Archive tier. Bulk retrievals are also the
lowest-cost retrieval option when restoring objects from S3 Glacier Deep Archive.
They typically finish within 48 hours for objects stored in the S3 Glacier Deep Archive
storage class or S3 Intelligent-Tiering Deep Archive tier.
For more information about archive retrieval options and provisioned capacity for
Expedited data access, see Restoring
Archived Objects in the Amazon S3 User Guide.
You can use Amazon S3 restore speed upgrade to change the restore speed to a faster speed while it is in progress. For more information, see Upgrading the speed of an in-progress restore in the Amazon S3 User Guide.
To get the status of object restoration, you can send a
HEAD request. Operations
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 S3 User 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 S3 User Guide.
A successful action returns either the
200 OK or
202 Accepted status
If the object is not previously restored, then Amazon S3 returns
in the response.
If the object is previously restored, Amazon S3 returns
200 OK in the response.
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
Cause: 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 S3 Standard or Bulk retrievals.)
HTTP Status Code: 503
SOAP Fault Code Prefix: N/A

public virtual RestoreObjectResponse RestoreObject( String bucketName, String key, Int32 days )
The bucket name containing the object to restore. 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 Amazon Web Services 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. 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 Amazon Web Services 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.
