google cloud sql – CloudSQL PostgreSQL Database storage is Increasing

I have a database instance (PostgreSQL v12.6) on Google Cloud and since 10 days ago, the Storage of Database is increasing rapidly.

Here’s my Observations:

list of Dtabases

Dashboard of Disk Space

From the second image, the data[App data] & archived_wal_log data is increasing enormously from the last 10 days

we have enabled the Automated backups & Point-in-time recovery & also enabled the Autoscaling of storage. So it increases the storage whenever the size of Database increases.

Can anybody help on this, why Archived_wal_log is increasing and it doubles the App data

Thanks
