You can use HBR to back up NFS NAS files and restore them when necessary. This topic describes the preparations that you need to make before backing up data.
Authorize roles
- Log on to the HBR console.
- Choose .
- Authorization pages appear one by one, which require you to confirm the authorization of these roles.
Install Cloud Assistant
An ECS backup client must work with Cloud Assistant. By default, Cloud Assistant clients are installed on ECS instances that are created after December 1, 2017. To back up ECS instances that you bought before December 1, 2017, you must install the Cloud Assistant client.
Add a mount point
In the NAS console, add a VPC-type mount point for the created NFS NAS file system. For more information about how to add a VPC-type mount point, see Create a mount point.

Create an ECS instance
Create an ECS instance in the VPC where the mount point for the NAS file system resides. The CentOS operating system is used in this example. For more information, see Create an instance by using the wizard.

Mount the NFS NAS file system to the ECS instance
- Run the sudo yum install nfs-utils command to install the NFS client. The CentOS operating system is used in this example. For more information about how to install the NFS client in another Linux operating system, see Step 1: Install an NFS client.
- After installing the NFS client, mount the NFS file system. For more information, see Mount an NFS file system in Linux.
