Hi, As I speak time machine is backing up everything onto my new 500Gb portable hard drive. I also have a new 500Gb internal drive which I am going to install after the backup is complete. I was just wondering what exactly time machine backs up? Does it include things like firefox bookmarks? As I would be annoyed if I lost them. Also, once osx has bee installed on the new internal drive is there a way to use the time machine backup on the portable drive? I basically don't know how the files are stored on the portable drive when using time machine...i.e. whether it is a backup saved as one individual file, or many files? Thanks.
