I have a 2.4 GB backup file (course contains a lot of video, obviously, and we cannot use an external video server). I want to extract just a few activities and restore into another course. So I select a subset of activities (say 18 - 26 of 26 total) and the resulting backup file ends up being almost as large as the entire course backup file (2.2 gb or so).
I examined the backup file and in the "files" folder there are sub-folders that actually contain all of the videos from activities 1 - 17 even though I thought I had specifically excluded activities 1 - 17 from the backup.
I've tried modifying the backup.mbz file manually but cannot quite get it right. The closest I have come is to create a smaller backup file that does not contain the unwanted content; however, when restored it creates blank activities in addition to the subset of activities that I wanted.
Thanks!
