Time Machine backs up all content, excluding data you've excluded in the Time Machine preferences pane, most system caches/temporary files, and any data listed in the /Library/Preferences/com.apple.TimeMachine.plist's ExcludeByPath key.

When you restore from a Time Machine backup, all data is as it was when the last backup was performed. A perfect replica, from the user's side.

Certain Microsoft Office products may notice a change if you restore your Time Machine backup to another computer/hard drive, as it uses the hard drive's serial number to validate software authenticity.


Yes, it will create an exact copy of what is on your hard drive at that time, including every little email or conversation stored.
