A backup vault is a Hybrid Backup Recovery (HBR) warehouse used to store backup data on the cloud. You can create a remote mirror vault for a backup vault to meet disaster recovery requirements. You can also use a mirror vault for geo-disaster recovery or cross-region data restoration.

Note
  • After a mirror vault is created, data that is being backed up by a backup job in the source vault is synchronized to the mirror vault in real time. The historical backups stored in the source vault start being synchronized to a mirror vault 90 minutes after the creation of the mirror vault.
  • You can only create one mirror vault for each backup vault.
  • You can restore backups stored in a mirror vault but 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, select Overview.
  3. Locate a vault for which you want 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, you cannot select the region where the source vault is located.
  5. Enter the Vault Name. The name must be a maximum of 32 characters in length.
  6. Enter the Vault Description as required, and click Create.

Restore data from a backup stored in a mirror vault

If you attempt to restore data from a backup stored in a remote mirror vault, log on to the Hybrid Backup Recovery (HBR) console on an ECS instance that is located in the target region. Proceed as follows:
  1. Install a backup client on an ECS instance.
    Note Select the target mirror vault when selecting a vault.
  2. Locate the ECS instance in the HBR console, and then use the ECS instance to restore data from a backup.
    Note In the Restore Source field, select From Other ECS or From Local Client as required.
