This topic describes how to restore files across regions by using a mirror vault. A mirror vault is a repository where Cloud Backup 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
The files on the on-premises server are backed up. For more information, see Back up on-premises files.
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. However, 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
Log on to the Cloud Backup console.
In the left-side navigation pane, click Overview.
On the Overview page, select the region where you created the backup vault, for example, China (Hangzhou).
Find the information card of the backup vault and click Cross-Region Backup in the upper-right corner of the card.
In the Create Mirror Vault panel, configure the parameters and click Create. The following table describes the parameters.
NoteYou 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.
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.
To maximize the redundancy of your backup data, Cloud Backup uses zone-redundant storage (ZRS)-enabled backup vaults by default in regions that support ZRS-enabled backup vaults. For regions that support only locally redundant storage (LRS)-enabled backup vaults, Cloud Backup uses LRS-enabled backup vaults. You do not need to manually select a backup vault type.
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.
