Background
For users utilizing Tencent Cloud Object Storage (COS), if you need to migrate data from one bucket to another within the same COS service, we recommend using the following migration methods:
Online Migration: 1. Migration Service Platform (MSP)
Online migration: Cross-bucket replication
Migration Practices
Migration Service Platform
MSP is a platform that integrates various migration tools and provides a visual interface, helping users easily monitor and manage large-scale data migration tasks. The "File Migration Tool" within MSP assists users in migrating data from various public clouds and data source sites to COS.
The steps are as follows:
1. Log in to the MSP console.
2. Click Object Storage Migration on the left sidebar.
3. Click Create Task to create a task and configure it as needed.
4. Start the task.
During data migration, how fast the source data can be read depends on the network, and selecting a higher QPS concurrence when creating a file migration task will speed up the migration.
Cross-bucket replication
Bucket replication is a configuration feature provided by Tencent Cloud COS for buckets. By setting up replication rules, you can automatically and asynchronously copy incremental objects between buckets in different regions. Once bucket replication is enabled, COS will precisely replicate the object content (such as object metadata and version ID) from the source bucket to the target bucket, ensuring that the replicated object copies have completely consistent attributes.
Additionally, operations performed on objects in the source bucket, such as uploading or deleting objects, will also be replicated to the target bucket. For more information and instructions, please refer to Bucket Replication.
