Migrating large amount of data across regions is very demanding in terms of costs and time. In order to migrate OBS objects from Region_A to Region_B, we have the following solutions
- Object Storage Migration Service (OMS) – is an online data migration service that helps you quickly, easily, and securely move object data to Huawei Cloud Object Storage Service (OBS).
- obsutil – Command line tool for accessing and managing OBS on Huawei Cloud.
- Data Express Service (DES) – TB-scale data transmission service. It provides physical storage devices (such as Teleport, external USB hard disks, SATA disks, and SAS disks) to transmit terabytes of data to Huawei Cloud
- Software development kits (SDKs) – Developers can directly use API functions provided by OBS SDKs to obtain the OBS service capabilities
- Cross Region OBS Migration Solution – This document presents a solution used by HWC customers that are interested on reducing the migration cost & time by compressing files before migrating
| Argument Command | Value | Default | Description |
|---|---|---|---|
| -h, --help | None | False | Show this help message and exit |
| execution_type | execution_type | None | Use 'source' if script runs on ECS in same region as Source Bucket. Use 'destination' if runs on ECS in same region as Destination Bucket ["source", "destination", "source_and_destination"] |
| --clean_mode | clean_mode | False | True if you want to delete intermediate compressed files that have been successfully migrated, once migration finish |
| --thread_mode | thread_mode | True | True if you want to use multiple threads to speed up (high CPU usage) |
| --has_encrypted_bucket | has_encrypted_bucket | True | If source or destination buckets are encrypted, we can NOT compare the MD5 using ETAG, therefore, we can only compare with size |
| --display_statistics | display_statistics | True | Show migration statistics (estimation) |
| --max_files_transfer | max_files_transfer | 0 | Maximum files to transfer (mostly used for testing purposes). Zero (0, default) means all |
