Overview

Background

Conventional on-premises storage servers cannot meet the storage demands for massive amounts of data. The main reasons are as follows:

  • Storage capacity is subject to hardware devices. If the storage capacity becomes insufficient, you need to purchase disks and expand the capacity manually.
  • The initial deployment requires high investment and long construction period, but it quickly lags behind as enterprise services change so fast.
  • Network information vulnerabilities, technical vulnerabilities, and mis-operations may result in unbearable security risks.

In contrast, OBS provides massive, stable, and secure cloud storage capabilities. With OBS, you do not need to worry about the storage capacity because it can be expanded infinitely. OBS can store unstructured data of any type and size. OBS ensures high stability and security for your data, featuring a multi-level reliability architecture, server-side encryption, log management, and permission control. In terms of the cost, OBS is available upon service subscription, eliminating the need for the investment in physical server deployment and maintenance.

HUAWEI CLOUD provides migration solutions to help you migrate data from your on-premises storage servers to OBS in a cost-effective, secure, and efficient manner. You can select a suitable migration solution according to your data volume, time arrangement, and budget.

Migrating Through OBS Tools (online)

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 (online)

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)

Fees are charged based on CDM instance specifications and the running duration. For details, see CDM Pricing Details.

Migrating Through Disk-Based DES (offline)

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?

Fees are charged based on the number of disks and the running duration. For details, see DES Pricing Details.

Migrating Through Teleport-Based DES (offline)

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?

Fees are charged based on the data size and the running duration. For details, see DES Pricing Details.

Migrating Through Direct Connect (real-time)

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.
