You can use HBR to back up SMB NAS files and restore them when necessary. This topic describes the preparations that you need to make before backing up data.

Authorize roles

When using Hybrid Backup Recovery (HBR) to back up files from ECS instances, you must authorize two roles: AliyunHBRDefaultRole and AliyunECSAccessingHBRRole. After the authorization, HBR and ECS are accessible by each other. Proceed as follows:
  1. Log on to the HBR console.
  2. Choose ECS Backup > ECS File Backup.
  3. 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 SMB NAS file system. For more information about how to add a VPC-type mount point, see Create a mount point.

After adding the mount point, click Manage next to the file system in the Action column. On the File System Details page that appears, check the mount point path.

Create an ECS instance

Create an ECS instance in the VPC where the mount point for the NAS file system resides. For more information, see Create an instance by using the wizard.
Notice We recommend that you create an ECS instance in Windows 2012. In Windows 2016, you must run Alibaba Cloud HBR as the administrator due to operating system permission control.
