Sorry for such a newbie question, I've googled this but haven't found anything solid. I have been transcoding all my avchd from imovie or FCE, and never backed up the original raw files. But now space is becoming an issue, and I have to change my workflow. I will transcode everything to AIC, back up the raw files from the Canon, and delete all the AIC after the project, and saving the raw files for future use. The problem is, the ImageMixer that comes with the Canon is Windows only, what is the best way to back up on OS X? Many many thanks!
