Zimbra NG-Backup to S3 bucket

Hi Team,

I have noticed there is a S3 bucket configuration in zimbra admin console, is there a way to export a full zimbra NG backup to aws s3 bucket? I have a bash script to do this but I would like to know if this is supported with Zimbra 8.8.8? Appreciate the help!
