Mounting COS to Windows Server as Local Drive

Terakhir diperbarui:2021-06-22 10:22:53


    COS can be used on Windows mainly with APIs, COSBrowser, or COSCMD.

    However, users using Windows Server can only use COSBrowser as cloud storage, which is not friendly to run programs or perform operations. In this case, you can mount the cost-effective COS to Windows Server as local drive by reading this guide.


    Examples given in this document apply only to Windows 7 or Windows Server 2012 and later.


    Download and installation

    The following installation procedure is for your reference. You can perform the installation according to your OS:

    • Go to GitHub to download Winfsp.
      You can then install it with the default options.
    • Go to Git or GitHub to download Git.
      Git-2.31.1-64-bit.exe is downloaded as an example. You can then install it with the default options.
    • Go to Rclone or GitHub to download Rclone.
      rclone-v1.55.0-windows-amd64.zip is downloaded as an example. Note that you only need to decompress it to any directory named in English (decompressing to a path containing Chinese characters might cause an error). In this example, the package is decompressed to the E:\AutoRclone.

    If GitHub cannot be opened or offers a low download speed, you can find another way for the download.

    Rclone configuration

    1. Right-click This PC and then select Properties. Then, click Advanced system settings > Environment Variables > System variables > Path. Then, click New.
    2. In the pop-up window, enter the path where Rclone is decompressed (E:\AutoRclone) and then click OK.
    3. Open Windows PowerShell and run the rclone --version command to see whether Rclone is installed successfully.
    4. If Rclone is installed successfully, run the rclone config command in Windows PowerShell.
    5. In Windows PowerShell, enter n and then press Enter to create a New remote.
    6. In Windows PowerShell, enter the name of the disk (for example, myCOS) and then press Enter.
    7. From the options that are displayed, enter 4 (the one that contains Tencent Cloud) and then press **Enter.
    8. From the options that are displayed, enter 11 (the one that contains Tencent Cloud COS) and then press Enter.
    9. When env_auth> is displayed, press Enter.
    10. When access_key_id> is displayed, enter the SecretId of COS and then press Enter.

      Using sub-account permissions is recommended. You can go to Manage API Key to view your SecretId and SecretKey.

    11. When secret_access_key> is displayed, enter the SecretKey of COS and then press Enter.
    12. Choose the region of the bucket according to the gateway addresses of the Tencent Cloud regions that are displayed.
      The Guangzhou region is used as an example herein. Therefore, you can enter 4 (cos.ap-guangzhou.myqcloud.com) and then press Enter.
    13. Select the object permission (private or public-read) as needed, which takes effect only for objects that are uploaded later. public-read is used as an example herein. Therefore, you can press 2 and then press Enter.
    14. Select the storage class for your objects uploaded to COS. Default is used as an example herein. Therefore, you can press 1 and then press Enter.
      • Default: default option
      • Standard storage class: STANDARD
      • Infrequent access storage mode: Standard_IA
      • Archive storage mode: ARCHIVE

        To use the INTELLIGENT TIERING or DEEP ARCHIVE storage class, please use the modifying the configuration file method and then set the value of storage_class to INTELLIGENT_TIERING or DEEP_ARCHIVE.

    15. When Edit advanced config? (y/n) is displayed, press Enter.
    16. After confirming the information, press Enter.
    17. Enter q to complete the configuration.

    Modifying the configuration file

    After performing the configuration above, the Rclone configuration file, vrclone.conf, can be found in the C:\Users\Username\.config\rclone directory. You can directly modify the file to update the Rclone configuration.

    Mounting COS as local drive

    1. Open the installed Git CMD and run one of the following commands as needed:
      • Mount COS as a shared drive on a LAN (recommended):
        rclone mount myCOS:/ Y: --fuse-flag --VolumePrefix=\server\share --cache-dir E:\temp --vfs-cache-mode writes &
      • Mount COS as local drive:
        rclone mount myCOS:/ Y: --cache-dir E:\temp --vfs-cache-mode writes &
        • myCOS: Replace it with the user-defined disk name.
        • Y: Replace it with the drive letter you want to assign to the drive. Ensure that it does not overlap with other drive letters.
        • E:\temp: local cache directory, which can be configured as needed
      If “The service rclone has been started” is displayed, the mount is successful.
    2. Enter exit to close the terminal.
    3. Find the myCOS(Y:) drive in This PC.
      If you open this drive, you can see all buckets in the Guangzhou region. You can upload, download, create, delete files, and do more via the drive as needed.

      • If any error is reported during the process, you can view the error messages from Git Bash.
      • If you delete a bucket from the drive, the bucket will be deleted, regardless of whether there are objects stored in the bucket or not.
      • If you change the name of a bucket from the drive, the bucket name in COS will also be changed.

    Running the mounted drive automatically at startup

    The mounted drive will disappear after the server is restarted. Therefore, you can perform the following operations to set the drive to auto-run at startup.

    1. Create the startup_rclone.vbs and startup_rclone.bat files in the E:\AutoRclone directory.

    2. In startup_rclone.bat, write the following mount command:

      • If COS is mounted as a shared drive on a LAN, run the following command:

        rclone mount myCOS:/ Y: --fuse-flag --VolumePrefix=\server\share --cache-dir E:\temp --vfs-cache-mode writes &
      • If COS is mounted as a local drive, run the following command:

        rclone mount myCOS:/ Y: --cache-dir E:\temp --vfs-cache-mode writes &
    3. In startup_rclone.vbs, write the following code:

      CreateObject("WScript.Shell").Run "cmd /c E:\AutoRclone\startup_rclone.bat",0

      Please replace the path with the actual one.

    4. Cut the startup_rclone.vbs file to the %USERPROFILE%\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup directory.

    5. Restart the server.

    Relevant Operations

    Using a third-party tool to mount COS to a Windows server as local drive is also available. The following shows the mounting procedure using the TntDrive tool:

    1. Download and install TntDrive.
    2. Open TntDrive and then click Account > Add New Account to create an account.

      Main parameters are described as follows:
      • Account Name: user-defined account name
      • Account Type: account type. As COS is compatible with S3, you can select Amazon S3 Compatible Storage.
      • REST Endpoint: region of your bucket. For example, if your bucket resides in the Guangzhou region, set this parameter to cos.ap-guangzhou.myqcloud.com.
      • Access Key ID: the value of SecretId, which can be created/obtained at Manage API Key.
      • Secret Access Key: the value of SecretKey
    3. Click Add new account.
    4. In the TntDrive window, click Add New Mapped Drive to create a mapped drive.

      Main parameters are described as follows:
      • Amazon S3 bucket: path or name of the bucket. You can click the icon on the right to select a bucket. In this example, the bucket residing in the Guangzhou region that is set in step 2 is selected (mapping a bucket as a single network drive).
      • Mapped drive letter: drive letter of the mapped drive, which cannot overlap with existing drive letters
    5. Click Add new drive.
    6. Find the drive in This PC. If you want to map all buckets to the Windows server, repeat the steps above.
