CloudSync

CloudSync is a cloud drive synchronization application that allows rapid and secure data synchronization between the TNAS and cloud drives. CloudSync is a very practical and efficient one-stop cloud drive disaster recovery solution, which integrates a variety of cloud drive synchronization functions, including Google Drive, OneDrive, Amazon S3, Dropbox, Backblaze, Yandex disk, Aliyun, etc., providing two-way and one-way multiple cloud drive synchronization strategies and synchronization log monitoring functions.

1. Quick Start

Step 1. Create a Cloud Connection

1. Go to CloudSync > Connections;
2. Click the Create Connection button in the top right corner;
3. Select the target cloud service;
4. Enter credentials (Access Key/Secret Key or account password);
5. After successful verification, the connection will appear in the Connections list.

Step 2. Create a Sync Task

1. Go to Tasks > Add Task;
2. Configure the following parameters: Connection: Select the created cloud connection; Name: Enter a task name; Local Directory: Select the folder to be synced; Cloud Directory: Select the target cloud folder; Sync Mode: 1.Two-way Sync: Keep local and cloud in sync; 2.Download Only: Cloud → Local; 3.Upload Only: Local → Cloud (Supports encrypted upload); Conflict Policy: Overwrite / Rename; Filter Rules: Filter by file size and type;
3. Confirm and save the task.

Note

Sync mode:

1. Bidirectional Synchronization Mode: Real-time bidirectional synchronization between the local directory and the cloud directory ensures that the files in both directories are the same. Any modification (deletion, renaming, modification, addition) of files and folders at either end is thus synchronized to the other end.
2. Only download remote files: Download the files and folders from a cloud disk directory to the local directory. Files and folders under the local directory will not be uploaded to the cloud disk. The newly added files on the cloud disk will be synchronized to a local directory. The modified and renamed files on the cloud disk will overwrite the local files.
3. Only upload local files: This uploads the files and folders from a local directory to the cloud while preventing files and folders from being downloaded locally. The newly added local files are also synchronized to the cloud, so that the modified and renamed local files overwrite those on the cloud disk.

Encryption: In the upload-only tasks, the system will encrypt the selected synchronization files in advance to ensure their security before uploading them to the cloud. Additionally, in the same upload-only tasks, when files need to be downloaded from the cloud, the system will automatically decrypt them, ensuring that the local data remains unencrypted at all times.

2. Advanced Settings

• Polling Interval: Set the interval at which CloudSync checks for file changes;
• Bandwidth Limit: Restrict upload/download speeds to avoid consuming all bandwidth;
• Concurrency: Set the number of files to transfer simultaneously to improve transfer efficiency.

Note

Polling Cycle: The polling cycle refers to how often Cloud Sync polls the public cloud for changes and synchronizes those changes to the local folder. If you set the polling cycle to one hour, Cloud Sync will connect to the public cloud every hour and search for file changes. The maximum polling cycle is one day (86,400 seconds).

3. Task Management

On the Tasks page, you can perform the following operations:

• Enable / Disable: Start or pause a task;
• Edit Task: Modify file filter rules, conflict policies, file restrictions, etc.;
• Delete Task: Permanently remove a task;
• Settings: Configure polling interval and bandwidth limits.

4. Logs & Monitoring

• View Logs: Supports filtering by task and searching by keyword;
• Refresh: Update log content in real-time;
• Export: Save log files for troubleshooting;
• Delete: Clear all logs or logs for specific tasks;
• Retention Policy: Set rules for automatic log cleanup.
