Database Backup (DBS) provides subscription storage plans to help you reduce storage costs.

Background information

By default, backup storage, sandbox storage based on copy data management (CDM), and built-in DBS storage are billed on a pay-as-you-go basis. To store large amounts of data, we recommend that you use subscription storage plans because they are more cost-effective than pay-as-you-go storage. Storage plans of larger storage capacities provide larger discounts. For more information, see Comparison between storage plans and pay-as-you-go storage.

The following three types of storage plans are available in DBS.
  • Backup storage plans

    These storage plans can be used to offset the fees incurred for your account when you back up and store ApsaraDB RDS for MySQL, ApsaraDB RDS for PostgreSQL, ApsaraDB RDS for SQL Server, or ApsaraDB for MongoDB database data.

  • Sandbox storage plans

    These storage plans can be used to offset the fees incurred for your account when you use sandbox storage. For more information about the billing of sandbox storage, see DBS sandbox fees.

  • Backup instance storage plans

    You are charged for creating a pay-as-you-go backup instance and for storing backup data in built-in DBS storage. These storage plans can be used to offset the fees incurred for your account when you use built-in DBS storage.

Precautions

  • You can purchase and combine multiple storage plans. For example, two 1 TB storage plans are equivalent to one 2 TB storage plan.
  • After a backup storage plan is purchased, its specification cannot be changed.
  • If storage plans are exhausted, fees incurred by extra storage are charged on a pay-as-you-go basis.
  • Storage plans become invalid when they expire.
