A copy of an encrypted file is not encrypted unless it is created in an encrypted directory, meaning that file-specific encryption does not necessarily transfer during copy unless within an encrypted directory. An ACFS snapshot can indeed be ACFS encrypted. The command acfsutil encr on can be used to specify the encryption key length for a directory or file, allowing customization of encryption strength. The suggested answer mentioned role separation for encryption managers and auditors, but that is a misunderstanding of the acfsutil encr init command's purpose. Role separation is not established by that command.
