About Time Machine

[mathewgx]

Does Time Machine backups include only apps and settings or the entire macos?
I mean if you use Time Machine to restore to an empty disk would you have a fully working system or you have to first install the os ?

Yes, you can back up the OS in Time Machine and then use it as a startup disk in Lion 10.7.3 and later, and in a restore use it to restore the OS too:
