You can use the subscription billing method to pay for resources before you use these resources. After you purchase resource plans, you can reserve resources and obtain higher discount rates to reduce costs. This topic describes how to purchase Hybrid Backup Recovery (HBR) resource plans for different backup scenarios.

Usage notes

  • You can purchase HBR resource plans based on the total required capacity. For example, you need to purchase storage resource plan for database backup to back up databases that are hosted on Elastic Compute Service (ECS). You can purchase resource plans based on the total storage capacity of all ECS-hosted databases. You do not need to purchase a separate resource plan for each ECS-hosted database. You can also purchase resource plan for backup storage based on the total storage capacity of all databases in other backup scenarios.
  • You cannot purchase resource plans to deduct traffic fees because you are billed for traffic based only on the pay-as-you-go billing method. For more information, see Hybrid Backup Recovery (HBR) Pricing.

Scenarios in which ECS-hosted databases are backed up

HBR resource plans are divided into two categories. One category is used to back up ECS-hosted databases. The other category is used in other scenarios. The following table describes the details.
Note In the following table, the check mark (✓) indicates that you must purchase the resource plan in the scenario. The cross sign (×) indicates that you do not need to purchase resource plans in the scenario.
  • Scenarios in which ECS-hosted databases are backed up

    The scenarios include the backup of self-managed MySQL, Oracle, and SQL Server databases that are hosted on ECS instances. The backup of SAP HANA databases is not included.

    Scenario Resource plan of vault rental for database backup Storage resource plan for database backup Storage resource plan for continuous log backup
    Back up ECS-hosted databases

    Purchase only one resource plan for each region where the database resides.

    Purchase the resource plan based on the capacity of the database. The capacity of the resource plan is 1.5 times the capacity of the database. If the backup storage that you use exceeds the capacity of your resource plan, you can purchase a new resource plan to cover the excess usage.

    x

    If continuous log backup is not required, you do not need to purchase a resource plan of this type. If you require a resource plan for continuous log backup, purchase a resource plan based on the result of the following formula: Incremental data per day × Retention period.
