Backing up encrypted disks with unencrypted Time Machine

It says this, which from what I researched seems to say it doesn’t help me if they are encrypted. I’m confused what this means.
Is there a way I can remove the encryption? Should I?


I've never been a fan of "File Vault" which is what Apple calls its built in encryption. The proper way apple wants you to execute this is to have an encrypted backup drive to backup your file vault protected internal drive. Problem is…don't use file vault. Yes, it's extremely secure and would be great if you travel a tremendous amount and you're carrying the secret launch codes but other than that it's really not necessary for normal people. So you have two choices.

1. Ignore it.
2. Encrypt your backup drive which would require reformatting it to MacOS Extended Journaled Encrypted.
3. Decrypt your internal drive. Aka: turn off file vault.

I vote for number 3. To do this go to System Preferences/Security/File Vault. Turn it off and plug the computer up. It will take a very long time for the decryption to complete. 9like many hours)
