You can use Cloud Backup to archive data, and then search for and retrieve it as needed. Before you archive data, you must install a client on the source machine.
(Recommended) Use a RAM user's AccessKey
Resource Access Management (RAM) is an identity and access control service provided by Alibaba Cloud. RAM allows you to create and manage multiple identities under a single Alibaba Cloud account and assign different permissions to an identity or a group of identities. This ensures that different users have different levels of access to your resources.
Activating the backup client requires an AccessKey. Because a leaked AccessKey for your Alibaba Cloud account can compromise the security of all your resources, we strongly recommend that you use a RAM user's AccessKey. For more information about how to create a RAM user and an AccessKey, see Create a RAM user and Create an AccessKey.
Before you install or uninstall the client, check the installation path:
If a NAS directory is mounted on the installation path, you must use the
umountcommand to unmount the directory to prevent accidental deletion of NAS files.If other important directories or files exist in the installation path, move them to another directory to prevent accidental deletion.
