Enable Cloud SQL point-in-time recovery
SQL instances can optionally be specified, otherwise iterates all running non-replica SQL instances
This automatically creates a backup at the time of enabling, which takes a few minutes during which your database may be unavailable.
WARNING: Enabling/Disabling point-in-time recovery restarts the instance, causing an outage, so this script will prompt for confirmation before proceeding.
Requires automated backups to already be enabled, otherwise you' ll get this error:
ERROR: ( gcloud.sql.instances.patch) HTTPError 400: Invalid request: Point in time recovery must be disabled when backup is disabled.
See adjacent script to enable automated backups first:
