I assume you meant 4TB?
It does, but will overwrite older versions when it needs more space, and also only updates changed files. It won't take the full 4TB, considering it doesn't back up programs, OS, etc. iOS devices can get backed up to the computer (compressed), and will be included in the time machine backup. I think you're over-estimating how much storage space you'll need.
Your other option if you still think you'll run out of space is pick up 2 4TB external drives, and separate the backups.
