All good questions.
The second backup drive only had a couple images.
The actual video footage was on the main backup drive.
No, this is not a “backup” setting.
I literally drag and drop the entire project – library and all assets to the backup drive.
It is the exact same size as the original folder.
Everything is there. I know this because when I relink, it is from that drive.
Seems like this should be simple.
