Database Backup:Backup fees

Last Updated:Feb 06, 2024

When you use Database Backup (DBS) to back up data, you are charged backup fees based on the volume of backup data.

Subscription

DBS supports various backup schedule specifications. The free quota for data backup, unit price, and backup and restoration performance vary based on backup schedule specifications. The backup and restoration performance is measured by the amount of time required for backup and restoration.

The following formula is used to calculate the backup fees for a subscription backup schedule: Backup fees = Configuration fees + (Actual backup data size - Free quota for data backup) × Unit price of the backup schedule type.

For example, Company A plans to perform a full backup for a 150-GB database four times each month. The estimated total backup volume in the current month is 600 GB. Company A can purchase a backup schedule of one of the following types. The price is applicable in the Chinese mainland.

  • Fees for the micro type: USD 5 + (600 GB - 40 GB) × USD 0.117/GB = USD 70.52

  • Fees for the small type: USD 22 + (600 GB - 400 GB) × USD 0.055/GB = USD 33

  • Fees for the medium type are USD 35. The actual backup data size is less than the free quota. No additional fees are charged.

Note

In this example, the small type has the lowest price. However, if you require better backup and restore performance, we recommend that you purchase a type with higher specifications.

The following table describes the specifications of backup schedule types.

Note
  • If the databases and tables that you want to back up involve issues such as unreasonable table schemas, large tables, or large fields, and you select a backup schedule of relatively low specifications, the resources of the backup schedule may be insufficient to back up the databases or tables and backup exceptions may occur.

    In this case, we recommend that you select a backup schedule type with high specifications when you purchase the backup schedule, or upgrade the backup schedule to a type with higher specifications if an exception occurs, and then try again. If the issue still exists, you can join the DBS DingTalk group (ID 35585947) for technical support.

  • The fees displayed on the buy page prevail.

  • Higher specifications offer higher backup and restoration performance at lower unit prices. For more information, see Performance tests on backup and restoration.

  • You can only upgrade a backup schedule. You cannot downgrade a backup schedule. For more information, see Upgrade a backup schedule.

  • Each calendar month, you are allocated a free quota for data backup. If you do not use up the free quota within a month, the remaining free quota does not roll over into the next month.

  • If the total amount of data that you back up during a month exceeds the free quota, the excess data is charged based on the corresponding unit price.
