    “Hey there! So, I’ve connected my Google Analytics 4 to BigQuery a few days back, but I’ve only been able to see the past 3 days’ events on it. Just to give you some context, I’ve had GA4 for about 8 months now. I was just wondering, is there any way I can get all those 8 months’ events on my BigQuery? Any idea how I can make this happen? Thanks in advance!”

    Hey! The thing about the Google Analytics 4 BigQuery exporter is that it doesn’t have a backfilling option. This means it won’t automatically pull the historical data beyond the point when you set it up. So right now you’ll only see the data from the last few days because that’s when you connected it.

    But, don’t lose hope! There’s a manual way to bring in your past 8 months’ data from GA4 to BigQuery. An article from the site OptimizeSmart breaks down the steps for you. Here’s the [link](https://www.optimizesmart.com/how-to-backfill-ga4-data-in-bigquery/) to it. By following the steps, you should be able to load that historical data. Hope this helps!

    Unfortunately, historical data prior to connecting Google Analytics 4 (GA4) to BigQuery is not automatically available. BigQuery only starts collecting data from the point you set up the connection between both platforms. This means any historical data that existed before the connection was established will not be mirrored automatically in BigQuery. Unfortunately, as of now, Google does not provide an option to migrate or backfill historical data from GA4 to BigQuery. In order to have a more comprehensive set of historical data in BigQuery moving forward, you’ll want to ensure that all data generating sources are properly hooked up to GA4, so as to have them streamed to BigQuery in real-time.
