Configure a proxy server for the host of a backup client

Step 1: Prepare a proxy server

1. Prepare a server that has the Internet access.
2. Install Microsoft Visual C++ Redistributable for Visual Studio 2015-2019.
   VC_redist.x64.exe

   VC_redist.x86.exe

3. Download and decompress the package of Apache HTTP Server 2.4.
4. Modify the configuration file named Apache24\conf\httpd.conf.
   Note Change the path in Define SRVROOT "\Apache24" to the installation directory of Apache. For example, if Apache is installed in the root directory of the D drive, you can change the path to D:\Apache24.

   • Load modules.

     LoadModule proxy_module modules/mod_proxy.so
     LoadModule proxy_connect_module modules/mod_proxy_connect.so
     LoadModule proxy_ftp_module modules/mod_proxy_ftp.so
     LoadModule proxy_http_module modules/mod_proxy_http.so

   • Specify the listening port, for example, Listen 8888.
   • Set access permissions.

     ProxyRequests On
     ProxyVia On
     <Proxy *>
     Require all granted
     </Proxy>

5. Double-click Apache24\bin\httpd.exe to start the proxy service.

Step 2: Create a backup client

1. Log on to the HBR console.
   If the host runs a Linux operating system without a graphical user interface (GUI), use an intermediate host with a GUI as an agent to log on to the HBR console.
2. In the left-side navigation pane, choose Backup > On-Premises Backup > File.
3. In the top navigation bar, select the region where you want to store backup data.
   Note

   • If you use a virtual private cloud (VPC), select the region of the VPC. This guarantees a high backup speed.
   • If you do not use a VPC and you need to achieve optimal backup performance, select a region that is close to the location of the data that you want to back up.
   • If you do not use a VPC and you need to implement disaster recovery, select a region that is distant from the location of the data that you want to back up.
4. In the upper-right corner of the On-Premises Backup page, click Add Client.
5. In the Add Client pane, set the parameters.

   Parameter	Description
   Backup Vault	The backup vault where you want to store the backup data. A backup vault is a repository that HBR uses to store backup data. You can use a single vault to store backup data that is received from multiple backup clients. Backup vaults reside in different regions. You can select or create only a backup vault in the current region. If you have created backup vaults, click Select Vault, and select a backup vault from the Vault Name drop-down list. If you have not created backup vaults, click Create Vault and specify the Vault Name field. The name must be 1 to 64 bytes in length.
   Backup Client	The backup client that you want to add. You can select an activated client or create a client.
   Client Name	The name of the backup client. The name must be 1 to 64 bytes in length.
   Software Platform	The operating system that is running on the host from which you want to back up data. Valid values: Windows 32-bit Windows 64-bit Linux 32-bit Linux 64-bit
   Network Type	Virtual Private Cloud (VPC): Select this option if the host from which you want to back up data resides in a VPC and the VPC is in the same region as the backup vault. Public Network: Select this option if no VPCs are available.
   Use HTTPS	Specifies whether to use HTTPS for encrypted data transmission. Note that HTTPS compromises the performance of data transmission. Data that is stored in the backup vault is encrypted, regardless of the setting of this switch. If you modify the setting of this parameter, the modification takes effect on the next backup or restore job.

6. Click Create. Then, click Download Client.
   Note The backup client is used to connect the host to HBR. You can also download the backup client from the client list.
7. Click Download Certificate.

Step 3: Install the backup client

Step 4: Activate the backup client

After the backup client is installed, you can use the following methods to activate the backup client.

• Recommended. Activate the backup client in the HBR console.
  1. Log on to the HBR console.
  2. On the On-Premises Backup page, click File. Find the backup client and choose More > Activate Client in the Actions column. In the Activate Client step of the Add Client pane, set the following parameters.

     Parameter	Required	Description
     Client IP Address	Yes	The IP address of the backup client that your current host can access. You can specify an internal IP address or an Internet IP address. For example, the IP address can be 127.0.0.1 (default), 12.34.56.78:8011, or 87.65.43.21:8443. Note The IP address must be reachable from your browser in use.
     AccessKey Id	Yes	The AccessKey ID and AccessKey secret of the RAM user that is used to access HBR. For more information, see Create an AccessKey for a RAM user.
     AccessKey Secret	Yes
     Client Password	Yes	The password that is used to log on to the backup client. The password must be at least six characters in length
     Data Network Proxy	No	The information of the proxy server that is used to transmit backup data. Specify the information if a proxy server is used for data transmission. Note You can configure a data network proxy only for a backup client whose version is 1.11.11 or later.
     Control Network Type	No	The type of the network that is used to call the HBR API.
     Control Network Proxy	No	The information of the proxy server that is used to call the HBR API.
     Message Channel Network Type	No	The type of the network that is used to send messages from HBR to the backup client.

  3. Click Activate Client.

     The page of the backup client for files appears. You can then use the backup client to back up data. If the activation of a backup client fails, you can reactivate the client. For more information, see How can I reactivate a file backup client?

• Activate the backup client on the host
  1. Enter the URL of the backup client in a browser to log on to the backup client. The URL is in the format of http://<Client IP address>:<Port number>, for example, http://10****:8011.
  2. On the Register page that appears, set the following parameters and click Register.

     Parameter	Required	Description
     Certificate File	Yes	The certificate of the backup client. Upload the certificate that you downloaded in Step 2: Create a backup client.
     AccessKey Id	Yes	The AccessKey ID and AccessKey secret of the RAM user that is used to access HBR. For more information, see Create an AccessKey for a RAM user.
     AccessKey Secret	Yes
     Backup Data Network	No	The type of the network over which backup data is transferred. You can select Public Network or Alibaba Intranet.
     Control Network Proxy	No	The information of the proxy server that is used to call the HBR API. The information includes the username, password, IP address, and listening port number of the proxy server. If identity authentication is not required, leave the username and password unspecified.
     Data Network Proxy	No	The information of the proxy server that is used to transmit backup data. Specify the information if a proxy server is used for data transmission. The information includes the username, password, IP address, and listening port number of the proxy server. If identity authentication is not required, leave the username and password unspecified.
     Control Network Type	No	The type of the network that is used to call the HBR API.
     Message Channel Network Type	Yes	The type of the network that is used to send messages from HBR to the backup client.

After the backup client for files is activated, you can use it to back up files.
