A backup vault is a cloud warehouse used by Hybrid Backup Recovery (HBR) to store backup data on the cloud. You can create a mirror vault in a different region for a backup vault to meet disaster recovery requirements. When necessary, you can use the mirror vault for cross-region data restoration.

  • After a mirror vault is created, backup jobs that are running in the source vault are synchronized to the mirror vault in real time. The historical backups stored in the source vault start being synchronized to the mirror vault 90 minutes after the creation of the mirror vault.
  • You can create only one mirror vault for each backup vault.
  • You can restore backups from a mirror vault but you cannot back up data to a mirror vault.
  • You must delete a mirror vault before deleting its source vault.
  • A source vault is created when you create a backup client.

Create a mirror vault

Proceed as follows:

  1. Log on to the HBR console.
  2. In the left-side navigation pane, click Overview.
  3. Locate a vault for which you need to create a mirror vault, click the icon in the upper-right corner.
  4. In the Create Mirror Vault dialog box, select a region where the new mirror vault is located.
    Note For disaster recovery, we recommend that you do not select the same region where the source vault is located.
  5. Enter the Vault Name. The vault name must be a maximum of 32 characters in length.
  6. Enter the Vault Description as required, and click Create.

Use a mirror vault to restore an SQL Server database

As shown in the preceding figure, if you need to restore a database in SQL Server Cluster A to SQL Server Cluster B, you need to log on to the HBR console on the server where SQL Server Cluster B is deployed, and register SQL Server Cluster B as an SQL Server instance. The procedure for restoring an SQL Server database from a mirror vault is as follows:

  1. Register the destination SQL Server instance.
    Note Select the mirror vault as the backup vault when registering the instance.
  2. Find the newly registered SQL Server instance in the HBR console and restore the database to this SQL Server instance.
