Create and manage on-demand and automatic backups

This page describes how to schedule and turn off automatic backups, create and manage on-demand backups, and view backups for your Cloud SQL instance.

For more information about how backups work, see Overview of backups.

Create an on-demand backup

To create an on-demand backup:

Console

  1. In the Google Cloud console, go to the Cloud SQL Instances page.

    Go to Cloud SQL Instances

  2. To open the Overview page of an instance, click the instance name.
  3. Select Backups from the SQL navigation menu.
  4. Click Create backup.
  5. On the Create backup page, add a description, if needed, and click Create.

gcloud

Create the backup:

gcloud sql backups create \
--async \
--instance=INSTANCE_NAME

You can provide a description of the backup using the --description parameter.

To create a backup in a custom location:

gcloud sql backups create \
--async \
--instance=INSTANCE_NAME \
--location=BACKUP_LOCATION

REST v1

  • instance-id: The instance ID

HTTP method and URL: 

POST https://sqladmin.googleapis.com/v1/projects/project-id/instances/instance-id/backupRuns

Schedule automated backups

To schedule automated backups for an instance:

Console

  1. In the Google Cloud console, go to the Cloud SQL Instances page.

    Go to Cloud SQL Instances

  2. To open the Overview page of an instance, click the instance name.
  3. Select Backups from the SQL navigation menu.
  4. Click Edit, next to Settings.
  5. Choose a window of time for your data to be automatically backed up.
  6. Click Save.

gcloud

  1. Edit the instance to specify a backup start time: 
    gcloud sql instances patch INSTANCE_NAME --backup-start-time=HH:MM
     The backup-start-time parameter is specified in a 24-hour time format, in the UTC±00 time zone, and specifies the start of a 4-hour backup window. Backups can start any time during the backup window.
  2. Confirm your changes: 
    gcloud sql instances describe INSTANCE_NAME
     In the backupConfiguration section, confirm that you see enabled: true and the time that you specified.

Terraform

To create a backup for a database, use a Terraform resource. 

resource "google_sql_database_instance" "default" {
  name             = "sqlserver-instance-backup"
  region           = "us-central1"
  database_version = "SQLSERVER_2019_STANDARD"
  root_password    = "INSERT-PASSWORD-HERE"
  settings {
    tier = "db-custom-2-7680"
    backup_configuration {
      enabled    = true
      start_time = "20:55"
    }
  }
  # set `deletion_protection` to true, will ensure that one cannot accidentally delete this instance by
  # use of Terraform whereas `deletion_protection_enabled` flag protects this instance at the GCP level.
  deletion_protection = false
}

Apply the changes

To apply your Terraform configuration in a Google Cloud project, complete the steps in the following sections.

Prepare Cloud Shell

  1. Launch Cloud Shell.

  2. Set the default Google Cloud project where you want to apply your Terraform configurations.

    You only need to run this command once per project, and you can run it in any directory.

    export GOOGLE_CLOUD_PROJECT=PROJECT_ID

    Environment variables are overridden if you set explicit values in the Terraform configuration file.

Prepare the directory

Each Terraform configuration file must have its own directory (also called a root module).

  1. In Cloud Shell, create a directory and a new file within that directory. The filename must have the .tf extension—for example main.tf. In this tutorial, the file is referred to as main.tf. 
    mkdir DIRECTORY && cd DIRECTORY && touch main.tf

  2. If you are following a tutorial, you can copy the sample code in each section or step.

    Copy the sample code into the newly created main.tf.

    Optionally, copy the code from GitHub. This is recommended when the Terraform snippet is part of an end-to-end solution.

  3. Review and modify the sample parameters to apply to your environment.
  4. Save your changes.
  5. Initialize Terraform. You only need to do this once per directory. 
    terraform init

    Optionally, to use the latest Google provider version, include the -upgrade option: 

    terraform init -upgrade

Apply the changes

  1. Review the configuration and verify that the resources that Terraform is going to create or update match your expectations: 
    terraform plan

    Make corrections to the configuration as necessary.

  2. Apply the Terraform configuration by running the following command and entering yes at the prompt: 
    terraform apply

    Wait until Terraform displays the "Apply complete!" message.

  3. Open your Google Cloud project to view the results. In the Google Cloud console, navigate to your resources in the UI to make sure that Terraform has created or updated them.

Delete the changes

To delete your changes, do the following:

  1. To disable deletion protection, in your Terraform configuration file set the deletion_protection argument to false. 
    deletion_protection =  "false"
  2. Apply the updated Terraform configuration by running the following command and entering yes at the prompt: 
    terraform apply

  1. Remove resources previously applied with your Terraform configuration by running the following command and entering yes at the prompt:

    terraform destroy

    Go to Cloud SQL Instances

  2. To open the Overview page of an instance, click the instance name.
  3. Select Backups from the SQL navigation menu to view recent backups, along with creation time and type of backup.

gcloud

  • List the backups of the instance: 
    gcloud sql backups list \
--instance INSTANCE_NAME

    You can filter and control the results using the standard list parameters. For a complete list, see the gcloud sql backups list command reference page.

View a list of backups during an outage

When an instance is in a region that is having an outage, you can only view backups for that instance using a wildcard (-) with the backupRuns.list API. The wildcard returns all backups in the project. See Restoring to a different instance.

When there's an outage in a region where an instance has customer-managed encryption keys (CMEK) enabled, you can't restore the backups for that instance to a different region. The reason is because Cloud SQL uses regional Cloud KMS keys for encryption when CMEK is enabled on the instance. To restore backups for a CMEK instance, Cloud SQL must have access to the CMEK key. In a regional outage, there's no access to the Cloud KMS keys in that region.

gcloud

  1. List the backups for every instance in a project: 
    gcloud sql backups list --instance -

    The command returns information similar to the following:

    {
      "kind": "sql#backupRun",
