You can use Hybrid Backup Recovery (HBR) to back up Apsara File Storage Network Attached Storage (NAS) files from Elastic Compute Service (ECS) instances and 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: Create an ECS file backup client

To create an ECS file backup client, follow these 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 to be backed up resides.
  4. On the ECS File Backup page, click the ECS Instance tab. On the ECS Instance tab, click Add ECS Instance in the upper-right corner.
  5. In the Add ECS Instance pane that appears, select an existing backup vault or select Create Vault to create one. Then, select the ECS instance that you created in preparations.
  6. Click Create.
    Wait for several minutes until the status of the target ECS instance becomes Activated on the ECS Instance tab

Step 2: Create a backup plan

After the ECS file backup client is created, follow these steps to create a backup plan:

  1. On the ECS Instance tab, find the target ECS instance and click Backup in the Actions column.
  2. In the Create Backup Plan pane that appears, set parameters as required and click OK.
    Notice You cannot use volume shadow copy service (VSS) to back up NAS files.

    The following table describes the parameters.

    Parameter Description
    Plan Name The name of the backup plan. If you do not specify this parameter, a random name is set by default.
    Source File Path The path of the mount point for the NAS file system.
    Start Time The start time of the backup plan. The time is accurate to seconds.
    Plan Run Interval The interval for backing up incremental data. Valid units: hours, days, and weeks.
    Retention The retention period of backup data. Valid units: days, weeks, months, and years.
    Using Flow Control Specifies whether to enable throttling. You can enable throttling to set bandwidth limits for backing up data from a directory during peak hours. This guarantees business continuity.
    Note If you set the value to Use, select a throttling period and enter the maximum bandwidth that can be used for backup during the throttling period based on business requirements. Then, click Add.

    After the backup plan is created, you can check it on the Backup Plan and Job tab. A NAS backup job starts based on the configured backup plan. You can also click Execute to run a backup job immediately.

    Then, you can check the progress of the backup job on the Backup Plan and Job tab.
