A backup vault is a repository that Hybrid Backup Recovery (HBR) uses to store backup data in the cloud. You can create a remote mirror vault for a backup vault and back up data in the backup vault to the mirror vault to meet disaster recovery requirements. The data in the backup vault is automatically replicated to the mirror vault.

Prerequisites

A backup vault is created by using the backup feature of HBR. You can view all the created backup vaults on the Storage Vaults page of the HBR console. For more information, see Manage backup vaults

Background information

Before you use a mirror vault, take note of the following information:

  • You can create only one mirror vault for each backup vault.
  • You can back up data to a remote mirror vault and restore backup data from the mirror vault. However, you cannot create backup plans for the mirror vault.
  • HBR starts to synchronize historical data in a source backup vault to the mirror vault 90 minutes after the mirror vault is created.
  • A mirror vault contains all the backup data that is stored in the source backup vault when the mirror vault is created. The mirror vault also contains the data that is generated in the source backup vault after the mirror vault is created.

Procedure

  1. Log on to the HBR console.
  2. In the left-side navigation pane, click Overview.
  3. On the Overview page, select the region where you created the backup vault, for example, China (Hangzhou).
  4. Find the information card of the backup vault, and click Cross-Region Backup in the upper-right corner of the card.

  5. In the Create Mirror Vault panel, set the following parameters and click Create.
    Note
    • You can create only one mirror vault for each backup vault.
    • You can back up data to a remote mirror vault and restore backup data from the mirror vault. However, you cannot create backup plans for the mirror vault. The historical backup data stored in the source backup vault is synchronized to a mirror vault 90 minutes after the mirror vault is created
    • When a mirror vault is created, the mirror vault contains all the backup data that is stored in the source backup vault.

    Parameter Description
    Region Select the region where you want to create the mirror vault.
    Vault Name Enter the name of the mirror vault.
    Data Redundancy Type This parameter is required only if the Backup Vault parameter is set to Create Vault. This parameter specifies the type of data redundancy for the mirror vault. The data redundancy mechanism improves data reliability of the mirror vault.
    • Locally redundant storage

      If LRS is enabled, HBR stores the copies of each object on multiple devices of different facilities in the same zone. This way, HBR ensures data durability and availability even if hardware failures occur.

    • Zone-redundant storage

      If ZRS is enabled, HBR uses the multi-zone mechanism to distribute data across three zones within the same region. If a zone becomes unavailable, the data can still be accessed.

    For more information, see Storage vault types.

    Description Enter the description of the mirror vault.

    After you create a mirror vault, you can view the progress of data synchronization. When the progress reaches 100%, it indicates that all data in the source backup vault is synchronized to the mirror vault.

What to do next

  • Delete a mirror vault

    Before you can delete a source backup vault, you must delete its mirror vault. To delete a mirror vault, you can find the information card of the mirror vault, and choose Settings > Delete in the upper-right corner of the card.

  • Restore data from a mirror vault
    1. Log on to the HBR console.
    2. In the left-side navigation pane, select the data source from which you want to restore data. For example, you can select OSS Backup.
    3. Select the region where the mirror vault resides.
    4. In the upper-right corner of the Restore Jobs tab, click Create Restore Job.

      In the Source Vault field, select the mirror vault that you created. For other parameters, make sure the settings are the same as the settings that you configured when you created the backup job. After the restore job is completed, data is restored to the data source in the region where the mirror vault resides.
