In ACP if you go to restore from a backup you get a list of the backup and you can select which one you want to restore.
I would think that most people want to restore the latest backup.
But as it is now the oldest backup is the one that is selected in the list at the bottom.
So i suggest that the newest backup is the one that is selected by default.
Other option could be to reverse the list so the newest item appear at the bottom of the list.
