A Clojure library to back up your Firestore to Google Storage

Clojure CI codecov


Environment variables:

  1. GOOGLE_CLOUD_PROJECT contains the name of the project containing both firestore and the cloud storage
  2. GOOGLE_APPLICATION_CREDENTIALS contains the .json credential for the service account being used.

magma uses alekcz/google-credentials to load Google Credentials from the GOOGLE_APPLICATION_CREDENTIALS

[alekcz/magma "0.3.0"]

(require '[magma.core :as magma])

;by default the root is called magma-<project-id>. 
;The bucket is called named after the root



(magma/backup-firestore "gs://bucket-name")

(magma/restore-firestore "gs://bucket-name/yyyy-MM-ddTHH:mm:ss.SSS")

(magma/roll-back-firestore) ;for your safety magma waits 60 seconds before starting the roll back

(magma/deleting-your-backups-is-a-really-bad-idea "yyyy-MM-ddTHH:mm:ss_SSS")

;Renaming the root
(magma/rename-root "namespace")
; The root is now magma-namespace-<project-id>
; This function primarily exists to enable testing

I'm currently using magma to backup my DB just before I deploy a change to my production API.
