// To deploy after any changes:

// To manually run a backup: Click "Run Now" on the backupDb script
// https://console.cloud.google.com/cloudscheduler?project=mantic-markets

// Backups are here:
// https://console.cloud.google.com/storage/browser/manifold-firestore-backup
//
// To import the data into dev Firestore (from https://firebase.google.com/docs/firestore/manage-data/move-data):
// 0. Open up a cloud shell from manticmarkets@gmail.com: https://console.cloud.google.com/home/dashboard?cloudshell=true
// 1. `gcloud config set project dev-mantic-markets`
// 2. Get the backup timestamp e.g. `2022-01-25T21:19:20_6605`
// 3. `gcloud firestore import gs://manifold-firestore-backup/2022-01-25T21:19:20_6605 --async`
// 4. (Optional) `gcloud firestore operations list` to check progress
