What is the problem that needs to be solved? Add an option (as it was in mLab) that allows to share the Cloud Provider Backup Snapshot (EBS Snapshot [1], in case of AWS) for Atlas Cluster with customer's Cloud Provider account. This action is easier, quicker and cheaper for customers than manually downloading the Atlas Snapshot.

Why is it a problem? (the pain) A) Operational pain: as of now (2020-02-18), if you require to execute disaster recovery scenario with restoration of your Atlas Cluster data outside of Atlas Clusters you'll need to create a Cloud Provider Backup Snapshot Restore job (POST /groups/[GROUP-ID]/clusters/[CLUSTER-NAME]/backup/restoreJobs/ Public API call [2]), then wait until that job will be finished and then manually download Atlas Snapshot(s) via HTTPS; B) Additional cost associated with manual restoration procedure: in order to know which Backup Snapshot file is related to which Shard/CSRS you'll need to download it, untar and check mapping.
