automate JIRA Cloud Backup export and push to Amazon S3 storage

Today, to perform a backup, we must log in to JIRA Cloud as an administrator, request a backup be created, wait; then download the backup and push it to long-term storage.

This could be automated by giving some system JIRA Cloud administrative credentials (those required to perform and download backup files), but that would be a very bad security design, and would be a bit complicated since the time delay between requesting the backup be created and when the backup is ready to be copied is variable.

I propose an automation enhancement in JIRA Cloud which would create the backup export on a schedule, then push it to Amazon S3 storage. S3 storage may be accessed using AWS IAM credentials which can be highly restricted, basically having only write access to only one subfolder in one bucket, which is much safer than the current option to give JIRA Cloud administrative credentials to a script to pull the backup from Atlassian.
