I have two questions: 1. On my PC I used to use SyncBack SE to sync my work documents folder to my dropbox folder every week. That way whatever changes I made during the week were automatically synchronized (changes only) to my dropbox folder via a scheduled backup. Is there a Mac equivalent for this? It would really help! 2. I am using Lightroom 3 for my photo management but I kind of liked the interface of iPhoto so I want to be able to use that too. Is there a way to have iPhoto create a library that DOES NOT make a copy of my 30+ GB of photos? I like the way LR just adds them to the library without making a copy of them and I can work with them without changing the folder substructure that I have in finder.
