Google Cloud Storage and Databases Explained

This was really helpful & informative.

Actually I have 1TB firestore data that keeps growing with some fresh data everytime, that needs to be backed up every 3 hours in cloud storage. I dont want to keep more than three versions of same object. Want to have minimal cost incurred. was thinking of puting data in coldline storage with Age policy to 1 day meaning delete if data is 1 day old. Please can you suggest how to do

I recommend you to take a look to a Decentralized cloud storage... a storages that keeps your data yours... for example, Internxt.
