Operating in China or using Tencent Cloud? RcloneView connects to Tencent COS via the S3 API and syncs your data to international clouds — bridging the gap between Chinese and global infrastructure.

Tencent Cloud Object Storage (COS) is one of the leading cloud storage services in China, widely used by businesses operating in the Chinese market. But syncing COS data to international providers like AWS S3 or Google Drive for global access, redundancy, or compliance typically requires custom scripts. RcloneView makes this visual and automated.

Why Sync Tencent COS to International Clouds?

Global accessibility — COS is optimized for China. International team members need data on S3 or Google Drive.
Multi-cloud redundancy — Storing data in both Chinese and international clouds protects against regional issues.
Compliance — Some regulations require data copies outside mainland China, or vice versa.
Migration — Moving workloads between Tencent Cloud and AWS/GCP.

Connecting Tencent COS

Tencent COS supports the S3 API:

Click Add Remote → select Amazon S3.
Choose Tencent COS from the S3 provider dropdown.
Enter your credentials:
- SecretId and SecretKey from Tencent Cloud console.
- Endpoint: Your regional endpoint (e.g., cos.ap-beijing.myqcloud.com).
- Region: Your bucket region (e.g., ap-beijing, ap-shanghai).
Save — your COS buckets are now browsable.

Browse COS Alongside International Clouds

View Tencent COS buckets side by side with AWS S3, Google Drive, or any other remote:

Sync Scenarios

Tencent COS → AWS S3 (China to Global)

Create a Sync job: COS bucket → S3 bucket.
Schedule daily for continuous replication.
International teams access data from S3.

Create a Copy job: COS → Google Drive folder.
Makes Chinese infrastructure data accessible to global Google Workspace users.

AWS S3 → Tencent COS (Global to China)

Create a Sync job in the reverse direction.
Ensure your Chinese operations have up-to-date data.

Performance Tip

Cross-border transfers between China and international regions can have higher latency. Recommendations:

Use 4–8 parallel transfers (not too aggressive due to cross-border latency).
Enable --fast-list for large buckets.
Schedule during off-peak hours for best throughput.
Consider bandwidth limits during business hours.
