Each time Database Backup (DBS) performs a backup based on a backup schedule, a backup set is generated. This topic describes how to manually delete a backup set that you no longer need in the DBS console to reduce the storage costs.
Prerequisites
Three full backup sets exist for the backup schedule that you want to manage.
If this prerequisite is not met, you cannot delete a backup set for a backup schedule.
Limits
You can delete only a single backup set at a time. You cannot delete multiple backup sets at a time.
You can delete only full backup sets. You cannot delete incremental backup sets.
To ensure the continuity of the restored data, you can delete only the earliest backup set.
Procedure
Log on to the Database Backup (DBS) console.
In the left-side navigation pane, click Backup Schedules. In the top navigation bar, select a region.
Find the backup schedule that you want to manage and click its ID. In the left-side navigation pane of the page that appears, choose
Find the backup set that you want to delete and click Delete Backup Set.
In the message that appears, click OK.
WarningYou cannot recover a deleted backup set. Proceed with caution.

If a large amount of data needs to be stored during a backup, we recommend that you purchase subscription DBS storage plans to offset the storage fees. For more information, see Use storage plans. Storage plans are more cost-efficient than the pay-as-you-go billing method.
You can configure the lifecycle of backup sets. DBS dumps and clears backup sets based on the lifecycle rules that you specify. For more information, see How do I manage the lifecycle rules of backup sets?
