Back up and restore data

This page describes how to use the Firestore scheduled backups feature. Use backups to protect your data from application-level data corruption or from accidental data deletion.

Backups let you configure backup schedules to take daily or weekly backups of the specified database. You can then use these backups to restore data to a new database.

About backups

A backup is a consistent copy of the database at a point in time. The backup contains all data and index configurations at that point in time. A backup does not contain database time to live policies. A backup resides in the same location as the source database.

Backups have a configurable retention period and are stored until the retention period expires or until you delete the backup. Deleting the source database does not automatically delete related backups.

Firestore stores metadata related to backups and backup schedules related to a database. Firestore retains this metadata until all backups for the database expire or are deleted.

Creating or retaining backups does not affect the performance of reads or writes in your live database.

Costs

When you use backups, you're charged for the following:

  • The amount of storage used by each backup.
  • For a restore operation, you're charged based on the size of the backup.

For more details and exact rates, see the Pricing page.

Before you begin

Make sure that billing is enabled for your Google Cloud project. Learn how to check if billing is enabled on a project.

Required roles

To get the permissions that you need to manage backups and backup schedules, ask your administrator to grant you one or more of the following Identity and Access Management roles:

  • roles/datastore.owner: Full access to the Firestore database

  • The following roles are also available but not visible in the Google Cloud console. Use the Google Cloud CLI to assign these roles:

    • roles/datastore.backupsAdmin: Read and write access to backups
    • roles/datastore.backupsViewer: Read access to backups
    • roles/datastore.backupSchedulesAdmin: Read and write access to backup schedules
    • roles/datastore.backupSchedulesViewer: Read access to backup schedules
    • roles/datastore.restoreAdmin: Permissions to initiate restore operations

Create and manage backup schedules

The examples below demonstrate how to set up a backup schedule. For each database, you can configure up to one daily backup schedule and up to one weekly backup schedule. You cannot configure multiple weekly backups schedules for different days of the week.

You cannot configure the exact time of day of the backup. Backups are taken at different times each day. For weekly backup schedules, you can configure the day of the week to take a backup.

Create a backup schedule

To create a backup schedule for a database, use the gcloud firestore backups schedules create command or the firebase firestore:databases:backups:schedules command.

Create a daily backup schedule

gcloud
To create a daily backup schedule, set the --recurrence flag to daily: 
gcloud firestore backups schedules create \
--database='DATABASE_ID' \
--recurrence=daily \
--retention=RETENTION_PERIOD

Replace the following:

  • DATABASE_ID: The ID of the database to back up. Set to '(default)' for the default database.
  • RETENTION_PERIOD: Set this to a value up to 14 weeks (14w).
Firebase CLI
To create a daily backup schedule, set the --recurrence flag to DAILY:

Terraform
To create a weekly backup schedule, create a google_firestore_backup_schedule resource. 
resource "google_firestore_backup_schedule" "weekly-backup" {
  project  = PROJECT_ID
  database = DATABASE_ID

  retention = RETENTION_PERIOD_SECONDS

  weekly_recurrence {

List backup schedules

To list all backup schedules for a database, use one of the following methods:

gcloud
Use the gcloud firestore backups schedules list command. 
gcloud firestore backups schedules list \
--database='DATABASE_ID'
Replace DATABASE_ID with the ID of the database. Use '(default)' for the default database.
Firebase CLI
Use the firebase firestore:backups:schedules:list command. 
firebase firestore:backups:schedules:list \
--database 'DATABASE_ID'
Replace DATABASE_ID with the ID of the database. Use '(default)' for the default database.

Describe backup schedule

To retrieve information about a backup schedule, use one of the following methods:

gcloud
Use the gcloud firestore backups schedules describe command: 
gcloud firestore backups schedules describe \
--database='DATABASE_ID' \
--backup-schedule=BACKUP_SCHEDULE_ID
Replace the following:
  • DATABASE_ID: The ID of the database to back up. Set to '(default)' for the default database.
  • BACKUP_SCHEDULE_ID: The ID of a backup schedule. You can view the ID of each backup schedule when you list all backup schedules.

Update a backup schedule

To update the retention period of a backup schedule, use one of the following methods:

gcloud
Use the gcloud firestore backups schedules update command: 
gcloud firestore backups schedules update \
--database='DATABASE_ID' \
--backup-schedule=BACKUP_SCHEDULE_ID \
--retention=RETENTION_PERIOD
Replace the following:
  • DATABASE_ID: The ID of the database to back up. Set to '(default)' for the default database.
  • BACKUP_SCHEDULE_ID: The ID of a backup schedule. You can view the ID of each backup schedule when you list all backup schedules.
  • RETENTION_PERIOD: Set this to a value up to 14 weeks (14w).

A restore operation writes the data from a backup to a new Firestore database.

To begin a restore operation, use one of the following methods:

gcloud
Use the gcloud firestore databases restore command: 
gcloud firestore databases restore \
--source-backup=projects/PROJECT_ID/locations/LOCATION/backups/BACKUP_ID \
