How to Set Up Automated Backups for Cloud Firestore Database

Automated backups are an essential part of any data management strategy, as they ensure that important information is not lost in the event of a disaster or system failure.

In this article, we will discuss how to set up automated backups for a Firestore database, and at the end, you'll have scheduled automated daily Firestore backups and will use different storages classes to reduce your backups storage cost.

Firestore is a NoSQL document database that is built for fast and flexible querying, and it is a popular choice for web and mobile applications. It is fully managed by Google Cloud, which means that it handles the infrastructure and scaling for you, so you can focus on building your application.


Here's a updated guide on setting up automatic backups for your Cloud Firestore project:

Getting Started

We use Firebase Cloud Functions to initiate the backups, so billing should be enabled on your Firebase Project.

First, create the Storage bucket for the backups

We'll want to create a storage bucket for your Firebase Project. To do so, on your Firebase Project, on the the Storage section, click on 'Add a bucket', then proceed to creating your bucket, by specificizing the Name of the bucket, the region, and the access frequency (Infrequent is a recommended option for backups).

"Creating a Storage bucket"

After creating the Storage bucket, the next step would be to setup the cloud function that would initiate the automated backups.

Create Cloud Function

We want to create a cloud function named dailyFirestoreBackup that'll be run every midnight.

import * as functions from "firebase-functions";
import * as admin from "firebase-admin";

const client = new admin.firestore.v1.FirestoreAdminClient();

export const dailyFirestoreBackup = functions.pubsub
  .schedule("0 0 * * *") // Every 24 hours (at midnight).
  .onRun(async () => {
    const projectId = process.env.GCP_PROJECT || process.env.GCLOUD_PROJECT;

    const bucketName = ""; //the name of your storage bucket

    const databaseName = client.databasePath(projectId, "(default)");
    const timestamp = new Date().toISOString();

    const dest = `gs://${bucketName}/firestore/${timestamp}`;

    try {
      const responses = await client.exportDocuments({
        name: databaseName,
        outputUriPrefix: dest,
        // Leave collectionIds empty to export all collections
        // or set to a list of collection IDs to export,
        // collectionIds: ['users', 'posts']
        collectionIds: [], // Leave empty to export all collections.
      const response = responses[0];
      console.log(`Operation Name: ${response["name"]}`);
    } catch (error) {
      throw new Error("Export operation failed.");


  • timestamp is the name of the backup.
  • databaseName is the name of the database we want to back up.
  • bucketName is the name of the Cloud Storage bucket where the backup will be stored.

And, finally, we want to deploy our cloud function, and we use the following command:

firebase deploy --only functions:dailyFirestoreBackup

To run the above command, it's important that we'll have the Firebase CLI configured on our machine.


Automated backups are a crucial part of any data management strategy, and they can help you protect your important information in the event of a disaster or system failure.

By following the steps outlined above, we'll have an automated backup system for our Firestore Database.
