Importing objects into a directory bucket

After you create a directory bucket in Amazon S3, you can populate the new bucket with data by using the import action. Import is a streamlined method for creating S3 Batch Operations jobs to copy objects from general purpose buckets to directory buckets.

Note

The following limitations apply to import jobs:

  • The source bucket and the destination bucket must be in the same Amazon Web Services Region and account.

  • The source bucket cannot be a directory bucket.

  • Objects larger than 5GB are not supported and will be omitted from the copy operation.

  • Objects in the Glacier Flexible Retrieval, Glacier Deep Archive, Intelligent-Tiering Archive Access tier, and Intelligent-Tiering Deep Archive tier storage classes must be restored before they can be imported.

  • Imported objects with MD5 checksum algorithms are converted to use CRC32 checksums.

  • Imported objects use server-side encryption with Amazon S3 managed keys (SSE-S3).

  • Imported objects use the Express One Zone storage class, which has a different pricing structure than the storage classes used by general purpose buckets. Consider this difference in cost when importing large numbers of objects.

When you configure an import job, you specify the source bucket or prefix where the existing objects will be copied from. You also provide an Amazon Identity and Access Management (IAM) role that has permissions to access the source objects. Amazon S3 then starts a Batch Operations job that copies the objects and automatically applies appropriate storage class and checksum settings.

To configure import jobs, you use the Amazon S3 console.

Using the Amazon S3 console

To import objects into a directory bucket

  1. Sign in to the Amazon Web Services Management Console and open the Amazon S3 console at https://console.amazonaws.cn/s3/.

  2. In the left navigation pane, choose Buckets, and then choose the Directory buckets tab. Choose the option button next to the directory bucket that you want to import objects into.

  3. Choose Import.

  4. For Source, enter the general purpose bucket (or bucket path including prefix) that contains the objects that you want to import. To choose an existing general purpose bucket from a list, choose Browse S3.

  5. For Permission to access and copy source objects, do one of the following to specify an IAM role with the permissions necessary to import your source objects:

    • To allow Amazon S3 to create a new IAM role on your behalf, choose Create new IAM role.

      Note

      If your source objects are encrypted with server-side encryption with Amazon Key Management Service (Amazon KMS) keys (SSE-KMS), don't choose the Create new IAM role option. Instead, specify an existing IAM role that has the kms:Decrypt permission.

      Amazon S3 will use this permission to decrypt your objects. During the import process, Amazon S3 will then re-encrypt those objects by using server-side encryption with Amazon S3 managed keys (SSE-S3).

    • To choose an existing IAM role from a list, choose Choose from existing IAM roles.

    • To specify an existing IAM role by entering its Amazon Resource Name (ARN), choose Enter IAM role ARN, then enter the ARN in the corresponding field.

  6. Review the information that's displayed in the Destination and Copied object settings sections. If the information in the Destination section is correct, choose Import to start the copy job.

    The Amazon S3 console displays the status of your new job on the Batch Operations page. For more information about the job, choose the option button next to the job name, and then on the Actions menu, choose View details. To open the directory bucket that the objects will be imported into, choose View import destination.
