Hello everyone. I just recently started using time machine backups about a month ago. I looked in my time machine backups, specifically at my pictures folder, and found that the only backup of my iPhoto library was in the finder pane that says "Now". The arrows to scroll back to previous backups are grayed out and cannot be clicked on, and I also cannot choose a different date by clicking the red tabs along the right side of the screen. I do know that you have to quit iPhoto in order for time machine to back it up properly, which I do. I also have 1.5 TB of free space on my time machine drive, so I know that space is not an issue. I just want to find out if I am doing something wrong, as I want to make SURE I have a good backup of all my 15,000 pictures and videos. Thanks in advance.
