Subscription (resource plans) is a billing method that allows you to pay for resources before you use these resource plans. After you purchase resource plans, you can reserve resources that can be used at a later point in time. Also, the resource plans allow you to save costs through higher discount rates. This topic describes how to purchase Hybrid Backup Recovery (HBR) resource plans for different backup scenarios.

Before you purchase HBR resource plans, take note of the following information:

  • Resource plans can be used in all the applicable scenarios. For example, you can purchase resource plans for backup storage to deduct storage fees in all backup scenarios. You can also purchase resource plans for file backup license. This can be used to deduct the license fees in both local file backup and ECS file backup scenarios.
  • You cannot deduct traffic fees from the resource plans that you purchase. For more information about pay-as-you-go billing method, see Hybrid Backup Recovery (HBR) Pricing.
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 provides further details.
Note In the following table, the ✓ indicates that you must purchase the resource plan in the scenario. In the following table, the x indicates that you do not need to purchase resource plans in the scenario.
  • Scenarios where ECS-hosted databases are backed up

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

    Scenario Resource plan of warehouse 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 that you want to back up 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 you use exceeds the capacity of your resource plan, you can purchase a new resource plan to cover the excess.

    You are not required to purchase a resource plan for continuous log backup. 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.
