For my “thing”, I use Firestore to persist state. I like Firestore a lot and, having been around Google for almost (!) a decade, I much prefer it to Datastore.
Firestore has a managed export|import service and I use this to backup Firestore collections|documents.
I’d been doing backups manually (using gcloud) and decided today to take the plunge and use Cloud Scheduler for the first time. I’d been reluctant to do this until now because I’d assumed incorrectly that I’d need to write a wrapping service to invoke the export.
