Type

Excessive Data Retention

## Explanation

Why the waste happens and who it affects.

Because backups accumulate over the retention window (and can grow quickly for high-change databases), excessive retention drives ongoing backup storage charges without improving practical recoverability.

## Billing model

The pricing dimensions that drive this cost.

Cloud SQL bills for backup storage ("Backups (used)") based on stored backup data over time. Longer retention increases stored backup volume and cost.

## How to detect

3 checks to find it in your estate.

- Review whether automated backup retention periods exceed documented recovery requirements

- Assess whether the retained window provides meaningful operational recovery value versus "just in case" storage

- Identify databases with high change rates where extended retention materially increases stored backup volume

## How to fix

2 ways to remove the waste.

- Reduce automated backup retention to the minimum that meets recovery and governance requirements

- Use a separate long-term retention approach for audit/compliance needs instead of extending operational backup retention indefinitely
