This topic describes how to restore files across regions by using a mirror vault. A mirror vault is a repository where Hybrid Backup Recovery (HBR) stores backup data in the cloud. To meet the requirements for backup and disaster recovery, you can create a remote mirror vault for a backup vault. You can use a remote mirror vault to restore data across regions.

Prerequisites

Files are backed up. For more information, see Back up files.
Note
  • You are charged for mirror vaults based on the storage usage.
  • After a mirror vault is created, incremental data in the backup vault is synchronized to the mirror vault in real time. The historical backup data that is stored in the backup vault is 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 data that is stored in a mirror vault. You cannot back up the data in a mirror vault.
  • Before you delete a backup vault, you must delete the mirror vault of the backup vault.
  • You can create a backup vault when you create a backup client.

Create a mirror vault

  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, configure the parameters and click Create. The following table describes the parameters.
    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. 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.
    • 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 a name for 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 the 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 a description for the mirror vault.

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

Restore data from the mirror vault

To restore data from the remote mirror vault, perform the following steps:

  1. Log on to the HBR console.
  2. In the left-side navigation pane, click On-Premises File Backup.
  3. In the top navigation bar, select the region where the mirror vault resides.
  4. Install the backup client for the server in the destination region.
    For more information, see Prepare for a data backup.
  5. 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. For more information, see Restore files.
    After the restore job is complete, data is restored to the data source in the region where the mirror vault resides.
