I have seen other posts but they seem to be stale at this point.
I am not sure what path would be easier for the dev team but there should be some way to do full system backups on a schedule, either through the Admin site or GhostCLI.
It would be nice if the backup was all in one file .zip or .tar that contained everything to restore the site. Also, a way to restore from this one file as well.
I have used scripts in the past but they seem to need modification as ghost matures.
