Journal Encrypted HD used for time machine

[Graph101]

I reformatted an HD w JOURNAL Encrypted to be used for time machine. Now, do i need to use "Encrypt backup disk"


What is the difference?

I dont want to double encrypt something. I would much rather encrypt the entire drive and anything inside it is just unencrypted....

I just use the encrypted hard drive and regular backups. I figure the hard drive is already encrypted, so I should be fine.

In the GUI, you can encrypt a disk with data only if it's the boot disk or a Time Machine disk. To encrypt the Time Machine disk, you would normally select the option in Time Machine Prefs.

Since you already formatted the disk with encryption enabled, you don't have to do anything else.

Once the unencrypted disk has been used for TM you won't be able to encrypt the TM disk unless you start the TM backups from scratch.

That was not my experience. My TM backup, on the now-encrypted disk, goes back to March and that limit is due to the disk's small capacity.
