You have multiple options to take backup but as you have not mentioned how and what you tried hard to answer.

You can use the normal CLI mongodump or mongoexport option to take a backup and use it for restart. But based on the size of the data it would be difficult to manage and plan to restore it.

If you need to restart to another Kubernetes could leverage the Tool Velero and take a Disk snapshot and restore to another K8s cluster if running in GKE.

Use third-party CLI or Operator to take a backup & upload to Bucket.
