I just started encryption with filevault 2 on OSX lion on my new Late 2011 macbook. 1) Can I put my macbook to sleep, restart it, or shut it down? If I do any of these things, will it mess up the encryption and destroy my HD? Do I have to leave my macbook on all night? 2) I can still use time machine normally, correct? Will time machine backups be encrypted also? I.e if I wipe my computer HDD and restore with time machine, will that restoration be encrypted since the hdd was encrypted during the time of that time machine backup? Thanks for any help.
