Install a Cloud Backup client before backing up an on-premises NAS file system - Cloud Backup

You can use Cloud Backup to back up files from on-premises NAS file systems. Then, you can use the backup files to restore data based on your business requirements. This topic describes the operations that you need to perform before you back up data.

(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.

Warning

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.
