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.

1.7 Changing Vault

Server backup vaults have two fi n 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 fi n of the associated vault from server backup to application-consistent backup. This section describes the detailed operations.

You can change the fi n of a vault from server backup to applicationconsistent backup, but not the other way around.

Procedure

Step 1 Log in to CBR Console.

1.Log in to the management console.

1.8 Replicating a Vault

CBR allows you to replicate a server backup vault, a hybrid cloud backup vault, or a fi system backup vault entirely to a replication vault in another region. Replicas of server backups in the destination region can be used to create images and provision servers. Replicas of fi system backups in the destination region can be used to create fi systems.

Two replication modes are available for replicating a vault.

●Select a backup vault and manually replicate it.

●	nfi	a replication policy to periodically replicate backups that have not
	been replicated or failed to be replicated to the destination region.

Constraints

●The replication rate of a single backup is about 80 MB/s. A maximum of eight backups can be replicated at a time.

● Data can be replicated to vaults in ff n destination regions. Creating replica will replicate all backups in the source vault to the destination vault.

●A server backup vault can be replicated only when it contains at least one backup that meets all the following conditions:

a.The backup is an ECS backup.

b.The backup contains system disk data.

c.The backup is in the Available state.

●Only vaults in the current region can be replicated. Replicas cannot be

replicated again but can be used to create images or fi systems.

● A backup vault can be replicated to ff n destination regions. The replication rule varies with the replication method:

–Manual replication: Backups can be replicated to the destination region as long as its replica is deleted from that region.

–Policy-driven replication: Once a backup has been successfully replicated to the destination region, it cannot be replicated to that region again, even if its replica has been deleted.

●Only regions with replication capabilities can be selected as destination regions.

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.
