Data stored on Apsara File Storage NAS file systems cannot be directly backed up. You need to use Hybrid Backup Recovery (HBR) to back up Apsara File Storage NAS data.

You can back up Apsara File Storage NAS data in the Apsara File Storage NAS console and restore backups as needed.
Note Apsara File Storage NAS backups do not take up space within the current file system.

Prerequisites

A NAS file system that complies with the network file system (NFS) or Server Message Block (SMB) protocol is created for backup. For more information, see Mount a file system on a Linux ECS instance and Mount a file system on a Windows ECS instance.

  1. Log on to the Apsara File Storage NAS console.
  2. Choose Data Service > File Backup and click Apply HBR Service.
  3. Activate the HBR service as prompted on the page.
