Hi, I've been using Time Machine to make backups to a Western Digital external ever since I got my Macbook Pro (12/2008). I haven't been modifying or creating many files on my computer recently, as I just finished school and mainly use it for web browsing. Nevertheless, my backups are about 250MB each, which is much larger than they used to be, and seems unreasonably large for doing nothing but web browsing. I have been using the Google Chrome beta as my primary browser, but I can't tie the start of unusually large backups to the start of my Chrome usage, as I just noticed the large backups now, weeks after I started using Chrome. I'm running Snow Leopard, and I recently formatted my Time Machine drive as it was running out of space, and started a new set of backups hoping that I might fix the problem. It's still doing it. Other info: my backup drive is connected all the time. Does anyone have similar issues? Is anyone familiar with the way that Chrome saves browser data in a Time Machine unfriendly way? Thanks in advance for your help!
