I used my My Book Thunderbolt Duo to store my Time Machine backup on Mavericks.
I installed Yosemite and FileVault is now a default option, so I checked it at install. When I selected the My Book Thunderbolt Duo again for Time Machine backup, it asked me if I wanted to encrypt the backup too, so I said yes.
Unfortunatly, I have an error message saying it can’t use encrypted Time Machine on a software Raid volume, so I had to disable encryption for it to work.
I tried to reformat my volume (Raid 0 - 4 TB) with latest WD Drive Utilities, but it’s definitly a no…
Is there a way to solve this ?
If no, and because I was thinking about changing my disk model for a new one, does the new My Passport Pro (which is a Raid portable drive) will have the same problem or is it a real hardware Raid system only showing a single volume under the Apple Disk Utility ?
If no, which disk choose (no NAS, I want DAS) ?
Thanks for help.
Surpriiise ! The Thunderbolt Duo is not a hard Raid volume !
