    Cloud Backup:Install a Cloud Backup client

    Last Updated:Mar 19, 2024

    Before you use Cloud Backup to back up files from an on-premises server or virtual machine (VM), you must install a Cloud Backup client on the server. Cloud Backup client supports Windows and Linux operating systems. You can select a Cloud Backup client based on your operating system.

    (Recommended) Create an AccessKey pair for a RAM user

    Resource Access Management (RAM) is an Alibaba Cloud service that allows you to manage user identities and control access to resources. RAM allows you to create and manage multiple identities for an Alibaba Cloud account, and grant multiple permissions to a single identity or a group of identities. This way, you can authorize different identities to access different Alibaba Cloud resources.

    An AccessKey pair is an identity credential and is required when you activate a Cloud Backup client. If you use the AccessKey pair of your Alibaba Cloud account, the AccessKey pair may be leaked and all cloud resources that belong to your account may be exposed to security risks. We recommend that you use the AccessKey pair of a RAM user to activate Cloud Backup clients. For more information, see Create a RAM user and Create an AccessKey pair.

    Usage notes

    • To achieve the optimal backup performance, we recommend that you run a Cloud Backup client on a host with the following configurations: 64-bit CPU with two or more cores and more than 8 GB available memory.

    • The volume of data that can be backed up depends on the available memory. For a host with 4 GB available memory, a maximum of one million files, up to 8 TB in total, can be backed up. If you want to back up tens of millions of files, we recommend that you configure 16 GB available memory.

    • Before you install and uninstall a Cloud Backup client, check the client installation path:

      • If a NAS file system is mounted to the installation path, run the umount command to unmount the NAS file system. This prevents the file system from being accidentally deleted.

      • If other important directories and files exist in the installation path, move them to another path. This prevents these directories and files from being accidentally deleted.

    • Before you use Cloud Backup, we recommend that you read the topics about the limits on Cloud Backup, the default backup speed, and the features available in each region. For more information, see Limits, Backup speed and recovery speed, Features, and Features available in each region.

    Related operations

    After the Cloud Backup client is installed, go to the Clients tab. Find the client and click the More icon in the Actions column, and then select the operation that you want to perform. The following table describes the operations.

    Operation

    Description

    Back Up

    Backs up files. For more information, see Back up files.

    Reactivate Client

    If the Cloud Backup client is abnormal, you can perform this operation. For more information, see How do I troubleshoot and handle the status exceptions on a Cloud Backup client?

    Delete Backup

    If you delete a backup point, all backup data generated by the Cloud Backup client is deleted and all backup and restore jobs that are being performed by the client fail.

    Important

    Before you delete a Cloud Backup client, make sure that you no longer need the backup data generated by the client and no backup or restore jobs are being performed by the client.

    Alert Settings

    Specifies the method that is used to send alert notifications if the Cloud Backup client, a backup job, or a restore job is abnormal.

    • Disabled: The Cloud Backup client does not send alert notifications.

    • Same as Backup Vault: The Cloud Backup client sends alert notifications by using the same method configured for the backup vault.

    • Notify Alibaba Cloud Account: The Cloud Backup client sends alert notifications to the owner of the Alibaba Cloud account by using emails.

    • Custom: If you select this option, you must select one or more alert contacts or alert contact groups. If an alert is triggered, the Cloud Backup client sends alert notifications to the selected alert contacts or alert contact groups. For more information, see Manage alert contacts.

    Client Settings

    Configures the Cloud Backup client. The following list describes the parameters:

    • Use HTTPS: specifies whether to use HTTPS to transmit encrypted data that is stored in a backup vault. If you use HTTPS to transmit data, the performance of data transmission is degraded. If you modify the setting of the Use HTTPS switch, the modification takes effect on the next backup or restore job.

    • Data Network: specifies the virtual private cloud (VPC) or public network over which data is transferred. If you have activated the VPC service in the region where the Cloud Backup client resides, we recommend that you select a VPC. This way, you can transmit data in a secure and reliable manner.

    • Maximum number of worker threads: specifies the maximum number of threads that can be run on the Cloud Backup client. A larger number of threads use more resources on the Cloud Backup client and have more negative impacts on the performance of the client. We recommend that you specify a suitable value based on your business scenario.

    • Maximum CPU Cores: specifies the maximum number of CPU cores that can be used on the Cloud Backup client. A larger number of CPU cores use more resources on the Cloud Backup client and have more negative impacts on the performance of the client. We recommend that you specify a suitable value based on your business scenario.

    • Data Network Proxy Mode: specifies the data network proxy mode. If you want to use a proxy, prepare the username, password, and IP address or endpoint of the proxy in advance.
