Hey guys, I know this is a very old thread, but I found a solution to this problem that worked for me that was much easier than the solution above, so I thought I would post it here for anyone else who may have this problem in 2014.
If you are trying to move your backups folder and you get the "ownership enabled" error message, go to finder, perform "get info" on the drive you are trying to copy to, unlock the drive settings by pressing the little lock on the bottom right corner of the info pane, and uncheck the line at the bottom that says "ignore owneship...". The direct drag-and-drop transfer of the backups folder should now work.
