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 lists specific solutions for migrating local data to OBS. For details, see Best Practices for Migrating Local Data to OBS.

Migration Method

Data Volume

Requirement

Time Taken

Cost

Using OBS Tools to Migrate Data

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.

Using CDM to Migrate Data

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.

Using Disk-based DES to Migrate Data

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.

Using Teleport-based DES to Migrate Data

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 number of disks and the running duration. For details, see DES Pricing Details.

Using a Direct Connect Connection to Migrate Data

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 backup software to back up local data to OBS.

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

The following table lists specific solutions for migrating data from a third-party vendor to OBS. For details, see Best Practices for Migrating Data from Third-Party Cloud Service Vendors to OBS.

Using OMS to Migrate Data

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.

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.
