I want to backup the encrypted home of a user who might be logged in at backup time. Which directories should I backup if I want to ensure that absolutely no plaintext data can be leaked? Are the following folders always encrypted?

/home/user/.Private
/home/user/.ecryptfs

Just want to make sure that no data leaks, as the backup destination is untrustworthy.

Edit: Yes, as Lord of Time has suggested, I'd like to know which folders and/or files I need to backup if I need to store only encrypted content in a way that allows me to recover it later with the right passphrase.
