You can use Hybrid Backup Recovery (HBR) to back up Apsara File Storage NAS files from Elastic Compute Service (ECS) instances. You can then restore these files if they are lost or damaged. This topic describes how to back up NAS files from an ECS instance.

Prerequisites

Preparations are completed.

Step 1: Install a backup client for ECS files

To create a file backup client for an ECS instance, perform the following steps:

  1. Log on to the HBR console.
  2. In the left-side navigation pane, choose Backup > ECS File Backup.
  3. In the top navigation bar, select the region where the ECS instance resides.
  4. In the upper-right corner of the ECS Instances tab, click Add ECS Instance.
  5. In the Add ECS Instance pane, select an existing backup vault. If you need to create a backup vault, click Create Vault. Then, select the ECS instance that you created in Preparations.
  6. Click Create.
    Wait for several minutes until the status of the ECS instance becomes Activated on the ECS Instances tab.

Step 2: Create a backup plan

After the backup client for ECS files is installed, perform the following steps to create a backup plan:

  1. On the ECS Instances tab, find the ECS instance, and click Back Up in the Actions column.
  2. In the Create Backup Plan pane, set the parameters and click OK.
    Notice Volume Shadow Copy Service (VSS) is not supported for backup of files from NAS file systems.

    The following table describes the parameters.

    Parameter Description
    Plan Name The name of the backup plan. By default, a random name is used.
    Source Paths The paths to the source files in the file system.
    Start Time The start time of the backup plan. The time is accurate to seconds.
    Backup Interval The interval at which data backup is performed. Unit: hours, days, or weeks.
    Retention Period The retention period of the backup data. Unit: days, weeks, months, or years.
    Throttle Bandwidth Specifies whether to throttle the bandwidth. You can throttle the bandwidth that is used for data backup during peak hours. This guarantees business continuity.
    Note If you select Yes, you must set the Throttling Period (Hour) and Max Bandwidth parameters. Then, click Add.

    After the backup plan is created, you can view the backup plan on the Backup Plans and Jobs tab. Backup jobs run based on the backup plan. You can also click Run Immediately to immediately run a backup job.

    You can view the progress of backup jobs on the Backup Plans and Jobs tab.
