# Managing data transfers

After you [create](/object-storage/transfer/launch) a data transfer, you can modify certain parameters, stop and resume it, or delete it.

## Prerequisites

Make sure you are in a [group](/iam/authorization/groups/index) that has at least the `editor` role within your tenant; for example, the default `editors` group. You can check this in the [Administration → IAM](https://console.nebius.com/iam) section of the web console.

## How to modify a data transfer

You can modify certain parameters of an existing data transfer:

* Name
* [Credentials](/object-storage/transfer/access#credentials) and [object key prefixes](/object-storage/transfer/key-prefixes) for both the source and destination buckets
* [Transfer type or stop condition](/object-storage/transfer/stop-condition)
* Inter-iteration interval
* [Settings for handling destination objects](/object-storage/transfer/destination-objects)
* [Limits on request rate and bandwidth](/object-storage/transfer/limits)

Changes may require several minutes to take effect, during which the old settings could still be in use temporarily.

You cannot change the names or endpoints of the source and destination buckets of a data transfer.

To modify a data transfer:

  <Tab title="Web console">
    1. In the sidebar, go to <Icon icon="https://mintcdn.com/nebius-ai-cloud/1Ha0sWR6e1mnIaHS/_assets/sidebar/storage.svg?fit=max&auto=format&n=1Ha0sWR6e1mnIaHS&q=85&s=0a2dad6b48aea10e85f6f3e2343aee26" width="16" height="16" data-path="_assets/sidebar/storage.svg" /> **Storage** → **Data Transfer**.
    2. Open the page of the data transfer that you want to modify.
    3. Switch to the **Settings** tab.
    4. Modify the parameters and click **Save changes**.
  </Tab>

  <Tab title="CLI">
    1. To get the data transfer ID, get a list of data transfers:
       ```bash theme={null}
       nebius storage transfer list
       ```
       The data transfer ID is returned in the `.metadata.id` parameter.
    2. Update the data transfer. For example, to change credentials for the source bucket in Nebius AI Cloud, run the following command:

       ```bash theme={null}
       nebius storage transfer update <data_transfer_ID> \
         --source-nebius-access-key-access-key-id <access_key> \
         --source-nebius-access-key-secret-access-key <secret_key>
       ```

       For more information about the command parameters, see the [command reference](/cli/reference/storage/transfer/update).
  </Tab>

  <Tab title="Terraform">
    1. Modify the [nebius\_storage\_v1\_transfer](/terraform-provider/reference/resources/storage_v1_transfer) resource in your Terraform configuration.
    2. Check that the configuration is correct:
       ```bash theme={null}
       terraform validate
       ```
    3. Apply the changes:
       ```bash theme={null}
       terraform apply
       ```
  </Tab>
</Tabs>

## How to stop and resume a data transfer

When you stop a data transfer, all ongoing uploads of objects and their parts are canceled. When you resume a data transfer, it starts a new [iteration](/object-storage/transfer/overview#iterations).
