# Manage Cloud Storage Lifecycle Policy using gcloud storage (Solution)

## Overview

* Labs are timed and cannot be paused. The timer starts when you click **Start Lab**.
    
* The included cloud terminal is preconfigured with the gcloud SDK.
    
* Use the terminal to execute commands and then click **Check my progress** to verify your work.
    

## Challenge scenario

You are managing a Cloud Storage bucket named `qwiklabs-gcp-01-cb18e338debe-bucket`. This bucket serves multiple purposes within your organization and contains a mix of active project files, archived documents, and temporary logs. To optimize storage costs, you need to implement a lifecycle management policy that automatically aligns the storage classes of these files with their access patterns.

* Design a lifecycle management policy with the following objectives:
    
    * **Active Project Files**: Files within the `/projects/active/` folder modified within the **last 30 days** should reside in **Standard** storage for fast access.
        
    * **Archives**: Files within `/archive/` modified within the **last 90 days** should be moved to **Nearline** storage. **After 180 days**, they should transition to **Coldline** storage.
        
    * **Temporary Logs**: Files within `/processing/temp_logs/` should be automatically deleted **after 7 days**.
