I would like to know if portable (and non-portable) encrypted vaults protects from rasomware, if the external drive is connected to the PC.

PLUS: Encrypted files backup are protected from rasomware? Encrypted files created with 7-zip are protected?

Encrypted files backup are protected from rasomware?
Very difficult to answer your question.
Usually, the ransomware uses a search routine, code based, for defined file extensions: png, jpeg, pdf, doc, etc.
Assuming that if you encrypt your files, would be useful to know if also the extension is encrypted.
In this case, theoretically, the ransomware could avoid these files.
Take this as a grain of salt, since no certainty exists in this context and every malware/ransomware can act in a totally unpredictable way.

Best practice is always to disconnect the external disk as offline support.
The risk is that ransomware might encrypt your files previously encrypted by you, making impossible to recover them even by paying the ransom.

Encrypting your files does not stop ransomware from encrypting your files again.

On the subject of vaults: It depends what you mean. Allow me to give an example and hope this answers your question:
Secure Folders is an application that allows me to lock folders by denying read/write access to them. If I were to be infected by ransomware and Secure Folders was activated and locking certain folders at the time of infection then the ransomware wouldn't be able to encrypt the files within said folders, but if the ransomware infection remained on my system and I unlocked any of those folders then the ransomware would go ahead and encrypt the files within.
I'd imagine it would work the same with any encrypted vault. Once you've unlocked that vault (which in turn decrypts the files inside and allows you access to modify them) the ransomware would have the opportunity to encrypt those files.
