Prepare for Cloud Backup data synchronization - Cloud Backup

Use Cloud Backup to synchronize data from File Storage NAS (NAS), HDFS, and Amazon S3 to Alibaba Cloud. Before synchronization, authorize Cloud Backup and install and activate a client.

(Recommended) Create an AccessKey pair for a RAM user

Resource Access Management (RAM) is Alibaba Cloud's identity and access management service. RAM lets you create multiple identities under one account and assign different permissions to users or groups, so each identity accesses only the resources it needs.

A Cloud Backup client requires an AccessKey pair for activation. If the AccessKey pair of your Alibaba Cloud account is leaked, all resources in the account are at risk. To reduce risk, use a RAM user's AccessKey pair to activate clients. For more information, see Create a RAM user and Create an AccessKey.

Warning

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

If a NAS file system is mounted to the installation path, run umount to unmount it. Otherwise, the file system may be accidentally deleted.
If important files or directories exist in the installation path, move them elsewhere to prevent accidental deletion.
