Can you please elaborate further? Are you saying that Time Machine backups ARE password protected when you are using a directly connected hard drive? Because I have not seen this to be the case.
Personally I take care of this issue by encrypting anything on my hard drive then I don't want someone to see if my MBP were stolen. That way, the backups are encrypted as well.
Thanks for the advice.
I want to save the TM Backup in a user specific folder on the USB Drive which is attached to the AEBS.
That folder should only be able to be accessed by the user who knows the password.
Well, if I turn on the accounts in the AEBS preferences I am not able to perform a backup using this user folder.
Neither the drive nor the folder show up.
Time Capsule on the other hand does support this feature.
