Data Replication Service (DRS) helps you migrate databases online and synchronize data in real time. It is stable, efficient, cost-effective, and easy to use.

  • Migration is free in certain scenarios.

Product Advantages
  • Easy to Use

    You can use this service for database migration and synchronization without professional technical knowledge.

  • Fast Set-up

    Migration tasks can be set up within minutes, in stark contrast to conventional database migration methods which can take days or months.

  • Low Costs

    DRS saves your manpower and hardware costs. You only pay for the resources used during the migration process.

  • Low Risks

    DRS is resilient and self-healing. It improves migration success rates through a variety of functions.

Application Scenarios
  • Migration to the Cloud

  • Cloud Data Redundancy

Migration to the Cloud

Migration to the Cloud

DRS online migration uses incremental migration technology. Source databases remain operational during migration, minimizing downtime and impact.


Optimal Performance

Parallel data export and import improve data migration speed.

Support for DDL

You can perform Data Definition Language (DDL) statements on the source database.

Minimal Downtime

DRS helps you migrate your databases with minimal or even no downtime.

Cloud Data Redundancy

Cloud Data Redundancy

DRS supports the local Internet Data Center (IDC) as a service center and HUAWEI CLOUD as a data redundancy center for recovery without too much investment on infrastructure.


Support for DDL

You can perform DDL statements on the source database.

Massive Capacity

DRS can easily monitor synchronization delays and compare data consistency.

Highly Resilient

If interrupted, synchronization can automatically continue from where it was halted to ensure data consistency.
