How Do I Migrate Data to OBS?

Migration Scenarios

The migration scenarios include:

  • Migrating local data to OBS
  • Migrating data from a third-party vendor to OBS
  • Migrating data between OBS buckets across accounts or regions, or in the same region

Scenario 1: Migrating Local Data to OBS

The following table describes the migration solutions.

Migration Method

Data Volume

Requirement

Time Taken

Cost

Migrating Through OBS Tool

Not larger than 1 TB

Sufficient public network bandwidth; requiring manual operations on clients or scripts to start data upload.

About 1 day for 1 TB data with the bandwidth of 100 Mbit/s

Data transmission is offered for free. Fees are charged only for storage space used on OBS.

Migrating Through the CDM Service

Less than 8 TB at a time

Subscription to the CDM service is required.

1 TB to 8 TB each day (depending on the network condition and the read and write performance of the data source)

Billing is based on CDM instance specifications and the running duration. For details, see CDM Pricing Details.

Migrating Through Disk-Based DES

Less than 30 TB at a time

Disks need to be prepared.

For details, see How Long Does It Take to Migrate My Data to HUAWEI CLOUD After I Have Created a DES Order?

Billing is based on the number of disks and the running duration. For details, see DES Pricing Details.

Migrating Through Teleport-Based DES

Less than 500 TB at a time

Huawei data centers provide Teleports for data transmission.

For details, see How Long Does It Take to Migrate My Data to HUAWEI CLOUD After I Have Created a DES Order?

Billing is based on the data size and the running duration. For details, see DES Pricing Details.

Migrating Through Direct Connect

More than 100 TB data that needs real-time online transmission every month

Private lines need to be deployed.

Depends on the bandwidth of the private line.

Fees are charged based on the distance and bandwidth of the private line. For details, see Direct Connect Pricing Details.

You can also use the backup software to back up local data to OBS.

Scenario 2: Migrating Data from a Third-Party Vendor to OBS

The following table describes the migration solutions.

Migration Speed

Cost

Migrating Through OMS

Full or incremental migration of large-scale object data (less than 500 TB)

For details about the supported third-party cloud service vendors, see Creating a Migration Task.

10 to 20 TB per day

For billing details, see OMS Pricing Details.

Migrating Through CDM Service

Small-scale data (less than 10 TB) migration or periodic migration

For details about the supported third-party cloud service vendors, see Supported Data Sources.

5 to 10 TB per day

Billing is based on CDM instance specifications and running status. For details, see CDM Pricing Details.

Back to Source by Mirroring (OBT)

Scenarios where data is seamlessly migrated to OBS. That is, service data is stored on the origin server created by the user and needs to be migrated to OBS without interrupting services.

Origin servers created by users

N/A

The price is subject to the billing mode of third-party cloud service vendors on cloud data reading.

Scenario 3: 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.

For details, see Migrating Data Between OBS Buckets.
