    I recently added a new 5tb drive as my external Time Machine backup destination. About half of that is full with my Time Machine backup data. I opted to encrypt the backup. The transfer has completed, and Time Machine has shown "Encrypting" for the past few days. It's moving, but quite slowly. Is this normal? Does the initial encryption of a full Time Machine backup usually take days, or has something gone wrong?

    If you have a lot of data on there, yes... it can take a long time.

    Run the below command in Terminal and it will show you how far along it is.

    Code:
    diskutil cs list
    The output of the command will look something like this. You can see in this example where 231 of 569GB is encrypted.

    Code:
    Encryption Status:           Unlocked
        Encryption Type:         AES-XTS
        Conversion Status:       Converting
        Conversion Direction:    forward
        Has Encrypted Extents:   Yes
        Fully Secure:            No
        Passphrase Required:     Yes
    Disk:                       disk6
        Status:                  Online
        Size (Total):            569869340672 B (569.9 GB)
        Size (Converted):        231454277632 B (231.5 GB)
        Revertible:              Yes (unlock and decryption required)
        LV Name:                 Heap
        Volume Name:             Heap
        Content Hint:            Apple_HFS

    Yup. 46% done.
    Can I safely reboot and it'll continue where it's left-off?

    Thanks for that command. Didn't know that one.
