This topic describes how to use Hybrid Backup Recovery (HBR) to back up data that is stored in Apsara File Storage NAS file systems. You can restore the data that is lost or damaged.

Prerequisites

  • A NAS file system is created. For more information, see Create a General-purpose NAS file system.
  • The backup service is activated. To activate the backup service, perform the following steps: Log on to the NAS console. In the left-side navigation pane, choose Data Service > File Backup. On the Welcome to NAS Backup Service page, activate the backup service as prompted.

  1. Log on to the NAS console.
  2. In the left-side navigation pane, choose Data Service > File Backup.
  3. Click Start to Backup File System.

    Note Each NAS file system enjoys a 60-day free trial for the first backup.

    1. Set the following basic parameters.
      Parameter Description
      File System The source NAS file system whose files you want to back up.
      Plan Name The name of the backup plan. By default, a random name is used.
      Start Time The start time of the backup plan. The time is accurate to the second.
      Continue Plan (Paid) Specifies whether to pay for the backup plan after its free trial ends.
    2. If you want to set the following advanced parameters, click Show Advanced Settings and click Switch to Paid Plan.
      Parameter Description
      Source File Path The path to the files that you want to back up, /nas/folder. You can enter a forward slash (/) to specify the root directory of the source NAS file system.
      Plan Run Interval The interval between two consecutive backup jobs. Unit: days or weeks.
      Backup Retention Policy The retention policy of the backup data. Valid values: Specify Retention Time or Forever.
      Retention The retention period of the backup data.

      If you select Specify Retention Time for the Backup Retention Policy parameter, you must set the Retention parameter. Unit: days, weeks, months, or years.

      Backup Vault Config The backup vault to store backup data. If backup vaults are available, set the value to Select Vault and select a backup vault from the Vault Name drop-down list. If no backup vaults are available, set the value to Create Vault and specify the Vault Name field. The name must be 1 to 64 characters in length.
      Note A backup vault is a repository where HBR stores data in the cloud. You can back up files from multiple NAS file systems to the same vault. You can select or create backup vaults only in the region where the file system resides.
      Vault Name The name of the backup vault.

      If you select Create Vault for the Backup Vault Config parameter, you must enter a vault name for the new backup vault.

What to do next

After the backup plan is created, files in the source NAS file system are backed up at the specified start time and at the specified intervals. You can perform the following operations on the backup plan:

  • On the Backup Plan tab, click Execute in the Actions column to start a backup job.
  • On the Backup Plan tab, choose More > Disable Plan in the Actions column to suspend the running backup job of the backup plan. To resume the paused backup job, choose More > Enable Plan in the Actions column.
  • On the Backup Plan tab, choose More > Delete Plan in the Actions column to delete the backup plan. After the backup plan is deleted, HBR no longer runs backup jobs for the plan but the backup data is retained.
  • On the Backup Plan tab, choose More > Backup History in the Actions column. You can view all the backups of the file system or the backups that are created over the last three months.
  • On the Backup Plan tab, click Edit in the Actions column to modify the backup plan.
    Note On the Backup Jobs tab, you can view the progress of backup jobs. After a backup job is completed, you can restore the backup data to the source file system or another file system.
