● A server backup vault stores backups of common servers.

● An application-consistent backup vault stores backups of database servers.

Vault Capacity (GB)

Vault capacity, which displays the capacity of the vault and the capacity used by backups in the vault.

For example: If 20/100 is displayed, 20 GB has been used out of the 100 GB vault capacity.

Associated Servers/ File Systems/Disks

Number of servers/le systems/disks associated with the vault. You can click the number to view details of an associated resource.

Step 3 On any backup page, click the Vaults tab and set lter criteria to view the vaults.

● Select a value from the status drop-down list to query vaults by status. Table

intermediat e state

An intermediate state when a capacity expansion, billing mode change, or specications change operation is in progress.

In this state, you cannot expand the vault capacity, change the billing mode, or change the

specications. However, you can perform

vault other operations, such as applying a policy and associating servers, le systems, or disks. After the capacity expansion, billing mode change, or specications change operation is complete, the vault status becomes Available.

Description

An intermediate state when a vault is being deleted.

In this state, a progress bar is displayed indicating the deletion progress. If the progress bar remains unchanged for an extended time, an exception has occurred. Contact customer service.

If your resources enter a pending deletion period in the case that your subscription has expired or your account is in arrears, or if the resources do not meet security requirements, your vault is put in the Frozen state.

If the resources are frozen due to arrears, the state will become Available after your account is topped up. Resources can then be used normally. If you do not top up your account in time, the system automatically deletes the frozen resources after the retention period expires. If the resources are frozen due to security reasons, contact customer service.

Error A stable

state

A vault enters the Error state when an exception occurs during task execution.

You can click Tasks in the navigation tree on the left to view the error cause. If the error persists, contact customer service.

● Search the vault by its name or ID.

● Click Search by Tag in the upper right corner to search for vaults by tag.

1.2 Deleting a Vault

You can delete unwanted vaults to reduce storage space usage and costs.

All backups stored in the vault will be deleted once you delete a vault.

Only pay-per-use vaults can be deleted. Yearly/monthly vaults need to be unsubscribed by following instructions in How Do I Unsubscribe from a Vault?.

Prerequisites

● At least one vault exists.

● The vault is in the Available or Error state.

● A hybrid cloud backup vault can be deleted only after you clear the corresponding backups both on-premises and in the cloud.

1.3 Dissociating a Resource

If you no longer need to back up an associated resource, dissociate it from the vault.

After a resource is dissociated from a vault, the automatic backup policies of the vault no longer have any automatic backups of the resource will be deleted. The deleted backup cannot be used for data restoration. Exercise caution when performing this operation.

1.4 Migrating a Resource

Migrating a resource means that you dissociate a resource from a vault and then associate it to another vault. All backups of the resource will be migrated to the destination vault.

Constraints and Limitations

● The source and destination vaults for resource migration must be in the Available state.

● The source and destination vaults for resource migration must be of the same

specications.

● The remaining capacity of the destination vault must be greater than the size of resource backups to be migrated.

Procedure

Step 1 Log in to CBR Console.

1. Log in to the management console.

2. Click in the upper left corner and select your region and project.

3. Choose Storage > Cloud Backup and Recovery. Select a backup tab from the left navigation pane.

Step 2 On any backup page, locate the destination vault and click the vault name. In this

example, we will be using the Cloud Server Backup page to illustrate the process.

Step 3 Click the Associated Servers tab. Find the target server and click Migrate in the

Operation column. See Figure 1-3.

Step 4 Select the destination vault and click Yes.

Step 5 View the migration progress on the Tasks page. If Status changes to Successful,

the resource has been migrated.

Cloud Backup and Recovery User Guide 1 Vault Management

Auto Capacity Expansion

If you want a vault to be automatically expanded when its capacity is used up, enable auto capacity expansion.

If this function is enabled, the vault size will be automatically expanded to 1.25x the capacity of the original vault when the maximum size limit has been reached.

Step 1 Log in to CBR Console.

1. Log in to the management console.

2. Click in the upper left corner and select your region and project.

3. Choose Storage > Cloud Backup and Recovery. Select a backup tab from the left navigation pane.

Step 2 On any backup page, click the name of the vault you wish to expand.

Step 3 On the vault details page, enable Auto Capacity Expansion.

Step 4 (Optional) Disable Auto Capacity Expansion if you no longer need this.

----End

1.6 Changing the Billing Mode from Pay-per-Use to Yearly/Monthly

● Yearly/monthly is a prepaid billing mode. You are billed based on the subscription duration you specify. This mode provides lower prices and is ideal when the resource use duration is predictable.

● Pay-per-use is a postpaid billing mode. You are billed based on your resource usage. With this mode, you can increase or delete resources at any time. Fees are deducted from your account balance.

If you want to use a vault for a long time, you can change its billing mode from pay-per-use to yearly/monthly to reduce cost. For details about the operations, see this section.

Prerequisites

A vault is in the pay-per-use billing mode.

Procedure

Step 1 Log in to CBR Console.

1. Log in to the management console.

1.7 Changing Vault

Server backup vaults have two specications: those for server backups and those for application-consistent backups.

● Server backups are backups of common servers.

● Application-consistent backups are backups of servers with databases.

If you need to back up a server that contains a database, change the of the associated vault from server backup to application-consistent backup. This section describes the detailed operations.

You can change the specications of a vault from server backup to applicationconsistent backup, but not the other way around.

1.8 Replicating a Vault

CBR allows you to replicate a server backup vault, a hybrid cloud backup vault, or a le system backup vault entirely to a replication vault in another region.
