A backup vault is a cloud warehouse used by Hybrid Backup Recovery (HBR) to store backup data on the cloud. A mirror vault is the mirror of a backup vault. The two vaults reside in different regions. You can use a mirror vault for geo-disaster recovery and cross-region data restoration.

Note
  • After a mirror vault is created, backup data in the backup vault is synchronized to the mirror vault in real time. The historical backup data in the backup vault starts to be synchronized to the mirror vault 90 minutes after the mirror vault is created.
  • You can create only one mirror vault for each backup vault.
  • You can restore the backup data that is stored in a mirror vault but cannot back up the data in a mirror vault.
  • You must delete a mirror vault before you can delete the corresponding backup vault.
  • You can create a backup vault when you create a backup client.

Create a mirror vault

To create a mirror vault, perform the following steps:

  1. Log on to the HBR console.
  2. In the left-side navigation pane, click Overview.
  3. Find the card of the backup vault for which you want to create a mirror vault. In the upper-right corner of the card, click Cross-Region Backup.
  4. In the Create Mirror Vault panel, set the following parameters and click Create.
    Parameter Description
    Region Select the region where you want to create the mirror vault.
    Vault Name The name of the mirror vault. The name must be 1 to 64 characters in length.
    Description The description of the mirror vault.
    Note To implement disaster recovery, you cannot select the region where the backup vault resides.

Restore data from a backup stored in a mirror vault

After you create a mirror vault, you can use the mirror vault to restore backup data based on your business requirements. To restore data from a backup file stored in the mirror vault, perform the following steps:

  1. Log on to the HBR console.
  2. In the left-side navigation pane, choose Backup > CSG Backup.
  3. Select the region where the mirror vault resides and register a gateway for the mirror vault. For more information, see Procedure.
  4. Restore data to the gateway. For more information, see Restore shares of a gateway.
    Note In this step, set the Restore From parameter to Other Gateway.
