Final answer:
The company should configure object lifecycle management to automate the transition of data older than 30 days to Coldline storage, thereby reducing manual intervention and costs.
Step-by-step explanation:
To minimize manual intervention when moving data older than 30 days to Coldline storage from Standard storage, the company should configure object lifecycle management.
This feature allows the company to set policies that will automatically transition their data to colder storage classes when the data reaches a certain age, such as 30 days. This automated approach is more efficient than writing custom code or using Cloud Scheduler to move the data manually. Object lifecycle management policies can handle large amounts of data seamlessly and ensure data older than 30 days is moved to a more cost-effective storage class without any manual effort.
