I am looking for a solution to backup my Cloud SQL schemas (and Cloud Storage files).
At first I tried using Cloud Scheduler to call the googleapis (https://cloud.google.com/sql/docs/postgres/import-export/exporting) in order to make an export of the database. The problem is that I need specific backup arguments, and I need to export specific schemas in the PostgreSQL database. Each of my clients has a schema, and i would like to be able to restore a schema without restoring the entire database. Googleapis don't seem to support exporting specific schemas (yet), which is why I would like to call pg_dump directly.
The same problem is with using automatic backups in Cloud SQL. I cannot restore a specific schema in a database, and I need to keep the backups around for atleast a month.
However, I have yet to find a way to call pg_dump using e.g. Cloud Functions. So currently I am thinking about using my own Windows 10 laptop to call pg_dump and to setup a daily task in Windows. I would much rather use Google Cloud, instead of my own laptop.
If anybody has any ideas of how to I should build my backup infrastructure, it would be greatly appreciated.
