Migrating Data Between OBS Buckets

Use Object Storage Migration Service (OMS) to migrate OBS data across accounts, across regions, or in the same region.

  • Cross-account migration: Data is migrated from a bucket in one HUAWEI CLOUD account to a bucket in another one.
  • Cross-region migration: Data is migrated from a bucket in one region to a bucket in another one.
  • Intra-region migration: Data is migrated between buckets in the same region.

About OMS

OMS is an online data migration service. It helps you migrate data from a third-party storage service to HUAWEI CLOUD OBS or migrate data between OBS buckets.

When using OMS, you need to specify only the source and destination OBS data information on the console, and then create a migration task or migration task group. For details about the differences between a migration task and a migration task group, see Application Scenarios of Migration Tasks and Migration Task Groups.

  • OMS is free until January 1, 2022. After the free trial expires, you will be billed only for data migrated by OMS. For details, see Product Pricing Details. During the migration, the APIs of the source and destination storage services are called to upload and download data. You will be billed for the API requests as well as data download and upload. For details about the fees, see Pricing Details.
  • During a cross-account migration, in addition to the fees for using OMS, the request fees and traffic fees will be also generated.
    1. Request fees: generated when OBS APIs are called. The fees are charged based on the number of requests, including PUT, POST, COPY, LIST, GET, and HEAD.
    2. Traffic fees: generated when data is downloaded from the source end. The traffic fees are charged by the source cloud service provider. Uploading data to HUAWEI CLOUD OBS is free.
  • OMS does not support the migration of objects of multiple versions.
