| Aug 22, 2021 at 13:55 | comment | added | Ezekiel | @StephenRasku Yeah, I'm not sure you'll be able to transfer the backups unfortunately. If this is important than you'll have to stick with Mac OS Extended | |

@EzekielElin, I've obtained a new external drive and formatted as APFS (Encrypted) as you suggested. However, when I try to cut and paste the backups from the "Top" disk I get "The volume is the wrong format for a backup." Trying to drag the backup to the new disk silently fails.

Updated screen shot to show all information.

| Aug 19, 2021 at 22:20 | comment | added | Ezekiel | I'm going to second this - the encryption/decryption process is not instant either - it takes time. You could try testing by restarting into recovery mode and trying to mount the disk with Disk Utility. | |
| Aug 19, 2021 at 21:27 | comment | added | jksoegaard | Yes, I'm very certain. Encryption cannot suddenly "disappear". | |
| Aug 19, 2021 at 20:57 | comment | added | Stephen Rasku | It seems that you are very certain about this. I have a password in a password manager for this drive and I don't recall removing the encryption. I do recall specifying encryption for Time Machine for an earlier OS. | |
| Aug 19, 2021 at 20:50 | comment | added | jksoegaard | @StephenRasku No, the backup is not encrypted. It is not the case that the UI has simply disappeared. Yes, you can definitely copy the saved backups to a different drive, reformat encrypted, and then move them back. | |
| Aug 19, 2021 at 20:27 | comment | added | Stephen Rasku | I think the backup on the unencrypted drive is encrypted but the UI for the password has disappeared so I can't be sure. Assuming that I have enough room to save the backups somewhere can I restore them to the newly formatted drive and use them as a TM backup? | |
| Aug 19, 2021 at 20:18 | comment | added | Ezekiel | The reason the right one is a logical volume is because it's an encrypted drive - this is normal. The one on the left is, in fact, not encrypted. | |

Not really an answer, but this might be a good time to reformat your external disk as APFS (Encrypted) instead, since Time Machine now supports that - and it's faster to complete backups. You can start with your "Top" disk being APFS and not modify your "Bottom" one for now. To do this, select the physical hard drive entry in Disk Utility and Erase, formatting as GUID/APFS Encrypted

Added requested information.

| Aug 19, 2021 at 15:34 | comment | added | Ezekiel | Are the drives actually unencrypted or are you just not needing a password? Open Disk Utility and select the volume. It will indicate whether it's encrypted or not there. | |
