    I've been trying to back up my iPhoto library to my .Mac iDisk for the past couple of days and it just performs a seemingly endless loop of "uploading" and "compressing." I would let that got for up to four hours and the backup still won't complete. My iPhoto library is 1GB and my iDisk has 14 GB allocated for it. Any advice? Thanks.

    .jpeg photos won't compress much (they are already compressed), so depending on how fast your internet connection is it could take a very long time to back up 1GB of photos.

    If you have an upload speed of 128kb/s then you will upload 16 kilobytes (8 bits per byte) per second, which comes to 960 kilobytes per minute. So every hour you will upload less than 60 megabytes, which means it would take around 20 hours to upload 1GB of photos. You can do the math to see how long it should take on yours, then I would recommend adding on 25% because ISPs are by definition scammers who won't give you what you pay for.
