Move and rename buckets

This page describes how to move the contents of a bucket by copying objects from a source to a destination bucket.

Overview

When you create a bucket, some of the properties you set are permanent and cannot be changed, including the bucket's name and the project it is part of. However, you can effectively move or rename your bucket:

  • If there is no data in your old bucket, delete the bucket and create another bucket with the properties you want

  • If you have data in your old bucket, create a new bucket with the properties you want, copy data from the old bucket to the new bucket, and delete the old bucket and its contents. The steps on this page describe this process.

    • If you want your new bucket to have the same name as your old bucket, you must temporarily move your data to a bucket with a different name. This lets you delete the original bucket so that you can reuse the bucket name.

    • Moving data between locations incurs network usage costs. In addition, moving data might incur additional charges, depending on the storage classes of the source data and on the location of the destination bucket. For more information, see Cloud Storage pricing.

Required permissions

Console

In order to complete this guide using the Google Cloud console, you must have the proper IAM permissions. If the buckets you want to access exist in a project that you did not create, you might need the project owner to give you a role that contains the necessary permissions.

For a list of permissions required for specific actions, see IAM permissions for the Google Cloud console.

For a list of relevant roles, see Cloud Storage roles. Alternatively, you can create a custom role that has specific, limited permissions.

Command line

In order to complete this guide using a command-line utility, you must have the proper IAM permissions. If the buckets you want to access exist in a project that you did not create, you might need the project owner to give you a role that contains the necessary permissions.

For a list of permissions required for specific actions, see IAM permissions for gcloud storage commands.

For a list of relevant roles, see Cloud Storage roles. Alternatively, you can create a custom role that has specific, limited permissions.

Move data from one bucket to another

Console

Use the Storage Transfer Service from within Google Cloud console:

  1. If you don't have a destination bucket yet, create the bucket.

  2. Open the Transfer page in the Google Cloud console.

    Open the Transfer page

  3. Click Create transfer job.

  4. Follow the step-by-step walkthrough, clicking Next step as you complete each step:

    • Choose a source: Use Google Cloud Storage bucket as your source type, and either enter the name of the wanted bucket directly, or click Browse to find and select the bucket you want.

    • Choose a destination: Either enter the name of the wanted bucket directly, or click Browse to find and select the bucket you want.

    • Choose settings: Select the option Delete files from source after they're transferred.

    • Scheduling options: You can ignore this section.

  5. After you complete the step-by-step walkthrough, click Create.

    This begins the process of copying objects from your old bucket into your new one. This process may take some time; however, after you click Create, you can navigate away from the Google Cloud console.

    To view the transfer's progress:

    Open the Transfer page in the Google Cloud console.

    Open the Transfer page

    To learn how to get detailed error information about failed Cloud Storage operations in the Google Cloud console, see Troubleshooting.

  6. Once the transfer completes, you don't need to do anything to delete the objects from your old bucket if you selected the Delete source objects after the transfer completes checkbox during setup. You may, however, want to also delete your old bucket, which you must do separately.

Command line

  1. If you don't have one yet, create a destination bucket.

  2. To recursively copy the contents of your source bucket to your destination bucket, use the gcloud storage cp command with the --recursive option:

    gcloud storage cp --recursive gs://SOURCE_BUCKET/* gs://DESTINATION_BUCKET

    Where:

    • SOURCE_BUCKET is the name of your original bucket. For example, old-bucket.

    • DESTINATION_BUCKET is the name of the bucket you are moving your data to. For example, my-bucket.

    If your bucket uses managed folders and a flat namespace, you must include the flag --include-managed-folders in the command for the managed folders to be copied.

  3. To recursively delete the contents from the source bucket, along with the source bucket itself, use the gcloud storage rm command with the --recursive option:

    gcloud storage rm --recursive gs://SOURCE_BUCKET

    Where SOURCE_BUCKET is the name of your original bucket. For example, old-bucket.

    Alternatively, to delete the contents from the source bucket without deleting the source bucket itself, use the gcloud storage rm command with the --all-versions flag and ** wildcard:

    gcloud storage rm --all-versions gs://SOURCE_BUCKET/**

    Where SOURCE_BUCKET is the name of your original bucket. For example, old-bucket.
