You can also back up File Storage NAS file systems using the ECS file backup feature. For more information, see Back up NFS file systems using the ECS file backup feature and Back up SMB file systems using the ECS file backup feature.
For the regions or NAS file systems that do not support ECS file backup, you can use on-premises NAS backup to back up file systems. For more information, see Back up NFS file systems using the on-premises file backup feature and Back up SMB file systems using the on-premises file backup feature.
