Restore an instance

This page describes how to restore your instance from a backup.

For information, best practices, and requirements for restore operations, see Overview of restoring an instance.

Restore an instance from a backup

You can use a backup to restore the same instance the backup was taken from, or you can use a backup to restore a different instance in the same project.

Restore to a different instance

When you restore from a backup to a different instance, you update the data on the target instance to the state of the source instance when you took the backup. For more information, see General tips about performing a restore and Tips and requirements for restoring to a different instance.

If you need a list of backups for the project and can't view them on the instance overview page due to an outage, you can use the backupRuns.list API with a wildcard (-). The wildcard option retrieves a list of all backups across all instances in the project. For more information, see Viewing backups during an outage.

Console

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

    Go to Cloud SQL Instances

  2. If the target instance has any read replicas, use the more actions menu More actions icon. on the far right side to delete them.
  3. To open the Overview page of an instance, click the instance name.
  4. Select Backups from the SQL navigation menu.
  5. Find the backup you want to restore from, and select Restore.
  6. In the Restore an instance from a backup page, confirm that you selected the correct backup in Review backup details.
  7. In Choose restore destination, select Overwrite an existing instance.
  8. From the Instance drop-down menu, select the instance you want to use for the restore. The instance that you select and all of its data are overwritten.
  9. To confirm your selection, enter the name of the instance to be overwritten in the Destination instance ID field.
  10. To start the restore process, click Restore.
  11. Check the status of the restore operation by going to the Operations tab of the target instance.
  12. After the restore operation completes, recreate any replicas you deleted previously.

gcloud

  1. Describe the target instance to see whether it has any replicas:
    gcloud sql instances describe TARGET_INSTANCE_NAME
    

    Note any instances listed in replicaNames.

    Repeat for each replica.

  3. List the backups for the source instance:
    gcloud sql backups list \
    --instance SOURCE_INSTANCE_NAME
    
  4. Find the backup you want to use and record its ID value.
  5. Restore from the specified backup to the target instance:
    gcloud sql backups restore BACKUP_ID \
    --restore-instance=TARGET_INSTANCE_NAME \
    --backup-instance=SOURCE_INSTANCE_NAME
        
  6. After the restore completes, recreate any replicas you deleted previously.

Restore to an instance in another project

You can use the project parameter to restore data to an instance in a different project than the one where the backup was taken. When using the project parameter, call restoreBackup in the project and on the instance you want to restore data to. When you restore from a backup to a different instance, you update the data on the target instance to the state of the source instance when you took the backup.

Permissions

The user restoring to a different project must have the cloudsql.instances.restoreBackup permission for the target project and the cloudsql.backupRuns.get permission for the source instance. These permissions are included in the Cloud SQL Admin role.
