This topic describes how to upgrade the public bandwidth for a file gateway in the Cloud Storage Gateway (CSG) console.

Background information

When you create a file gateway, the public bandwidth is not configured by default. However, if you need to upload data from a file gateway to an Object Storage Service (OSS) bucket that resides in a different region, you must configure a high public bandwidth to ensure the efficiency of data transmission. The higher the public bandwidth, the faster the data is transferred.
  • Only the public bandwidth of the file gateways that are deployed on Alibaba Cloud can be upgraded.
  • You can configure the public bandwidth when you create a file gateway. The default value is 5 Mbit/s.
  • You can upgrade the public bandwidth of a file gateway on the Gateways page.
  • This section describes the billing items of the public bandwidth feature.
    1. You are charged by Cloud Storage Gateway for configuring the public bandwidth feature. For more information, see Billable items and billing methods.
    2. You are also charged by OSS for accessing OSS resources. For more information, see Traffic fees.


  1. Log on to the .
  2. In the upper-left corner, select the region where the file gateway resides.
  3. In the left-side navigation pane, click Gateways. On the Gateways page, find the file gateway and choose More > Upgrade Network Bandwidth in the Actions column.
  4. In the Upgrade Network Bandwidth dialog box, configure the public bandwidth.
    Note The value of the public bandwidth must be greater than the current value and cannot exceed 200 Mbit/s. The default value is 5 Mbit/s.
  5. You can also configure the public bandwidth when you create a file gateway. In the Gateway Configurations wizard of the Create Gateway dialog box, select Public Network Bandwidth. For more information, see Create a file gateway.
    Note If you select Public Network Bandwidth, the default minimum value is 6 Mbit/s and the maximum value is 200 Mbit/s.
