You need the following to configure the remote backup

- You should have the Google Cloud Storage buckets ready. If you have not created the buckets, see Creating storage buckets.
- You should have the URL of the bucket in one of the following formats:
- In the GCS web console page for your bucket, under Settings > Interoperability, create an Access key for your service account and save the generated Secret.
- In case the nodes are on a private network, you need to assure that Private Google Access is enabled in your subnet to store backups in the storage. For more information, see Configuring Private Google Access.
