This is a utility to help restore CloudSQL backups accross projects as per the documentation here https://cloud.google.com/sql/docs/postgres/backup-recovery/restoring
This has only been tested against Postgres, your results may vary for other database engines.
const SqlRestore = ;restoreHelper = ;restoreHelper;backups = await restoreHelper;await restoreHelper;// Restores the most recent backupawait restoreHelper;
Here's an example of the output returned by listBackups
kind: 'sql#backupRun'status: 'SUCCESSFUL'enqueuedTime: '2020-07-24T14:52:14.591Z'id: '1595599200001'startTime: '2020-07-24T14:52:14.750Z'endTime: '2020-07-24T14:54:20.016Z'type: 'AUTOMATED'windowStartTime: '2020-07-24T14:00:00Z'instance: 'demo-instance'selfLink:''location: 'asia'backupKind: 'SNAPSHOT'
Service Account & Roles
To limit the scope of the service account, you may want to create custom roles so you can grant reading of backups to the source project and restoring of backups to the target project.
You should review the permissions needed to backup/restore instances.
Here's the permissions we've found work for backing up/restoring:
For your source project to list and access the backups:
cloudsql.instances.get cloudsql.instances.list cloudsql.backupRuns.list cloudsql.backupRuns.get
For your target project to restore a backup to it
cloudsql.instances.get cloudsql.instances.list cloudsql.instances.restoreBackup
Some common errors you might encounter
The client is not authorized to make this request Most likely a permissions error, check IAM.
This operation is not valid for this instance This error might occur if the target instance does not have enough storage to accommodate the backup. Try increasing storage to be the same as the source instance.
