A: BitLocker in Windows 8 did add support to back up a BitLocker recovery key to Microsoft SkyDrive. (See screen shot below.) However, this is only available provided the following is true:
  • The computer isn't a member of a domain.
  • The user's account is connected to a Windows Live ID.

Backup option, BitLocker

This means if your computer is part of a domain, then you can't save to SkyDrive (however, in that case a better option is to save the BitLocker recovery key to Active Directory anyway or use Microsoft BitLocker Administration and Monitoring).
