So I had initially sync'ed the folders using SFTP with Goodsync, and create timestamps were copied over, but when I go through the backup using OSX finder, it lists everything by modified date, which is showing the date of the SFTP sync and not the normal modified timestamp in the original folder on my local computer.
It is a cosmetic thing, and I know the system has to be looking at modified date, as that is how Yummy would be determining which file/folder would be newer when looking at two sync folders.
Anyway, thanks for getting back to me so quickly and helping me so much.
