Dear guys, I heard of some good comments about Mozy, and give it a try. I installed the client, and using the free 2GB account to backup around 200MB of files. Then recently I found my macbook not going to sleep. It would go to sleep if i close the lid, or choose to sleep from the menu, but not after the idle time set in energy saving option. The monitor does go to sleep, but the power indicator remains solid white. I suspect it is Mozy, and so I uninstalled the client. Then the problem goes away. To reconfirm this, I installed Mozy again and the problem comes back. And I uninstalled it again and the problem goes away again. Anybody experienced the same thing? Any configuration problem here? Thanks in advance for any suggestion! wil.
