[google-cloud-sql-discuss] Re: Point in Time Recovery for Cloud SQL for PostgreSQL

Hello,

You can follow the following thread to stay up to date about PostgresSQL Point in Time recovery [1]. 

For Spanner the recommended method is the import/export feature to GCS [2][3]. You can use the Cloud Dataflow connector [4] to move data from Spanner to GCS periodically but this requires manual work and coding running Dataflow pipelines on your own.

Spanner also has global replication [5] meaning the data will always be available if one site is down and has strong consistency [6]. 

So based on your requirements, Spanner would likely be your best option. You can see a table comparing all database solutions as well here [7].
