A backup vault is a repository that Hybrid Backup Recovery (HBR) uses 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.
- 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:
- Log on to the HBR console.
- In the left-side navigation pane, click Overview.
- 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 the icon.
- In the Create Mirror Vault pane, select the region where you want to create the mirror
vault.Note To implement disaster recovery, do not select the region where the backup vault resides.
- Enter a vault name. The name must be 1 to 32 characters in length.
- Enter a description of the vault and click Create.
Restore an SQL Server database from a backup stored in a mirror vault
If you need to restore the backup of a database in SQL Server Cluster A to SQL Server Cluster B, you must log on to the HBR console on a server in SQL Server Cluster B and register the destination SQL Server instance in the HBR console. To a database in SQL Server Cluster A to SQL Server Cluster B, perform the following steps:
- Register the destination SQL Server instance. Note When you register the instance, select the mirror vault.
- Find the registered SQL Server instance in the HBR console and restore the database to the destination SQL Server instance.
