## Impact

This rule is checking to ensure that AWS RDS Aurora Clusters have a feature called "backtracking" enabled. Backtracking allows users to navigate through the changes made to their database and revert back to any previous state without using a backup. This can be incredibly useful in situations where mistakes have been made or data has been lost. Not having this feature enabled could potentially result in data loss, increased recovery time in the event of an error, or the inability to recover data if a backup has not been recently made.

## How to Fix

*Resource:* aws\_rds\_cluster

* *Arguments:* backtrack\_window

## To fix this issue, you need to enable backtracking on your RDS Aurora Clusters. You can do this by including the `backtrack_window` argument in your `aws_rds_cluster` resource. The `backtrack_window` parameter specifies the target backtrack window, in seconds. If not specified or set to 0, backtracking is disabled. \[source,go]

## resource "aws\_rds\_cluster" "example" { cluster\_identifier = "example" engine = "aurora" master\_username = "example" master\_password = "example" db\_subnet\_group\_name = aws\_db\_subnet\_group.example.name vpc\_security\_group\_ids = \[aws\_security\_group.example.id] skip\_final\_snapshot = true backtrack\_window = 43200 //set the value in seconds ... }

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/appsec-rules/iac-security/storage/appsec-aws-326.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
