Two and a half reasons *not* to use BitLocker

Windows 7 BitLocker limits your choices when it comes to backup and booting from VHDs. I had to disable BitLocker for two (and a half) reasons:

  1. It’s not that easy anymore to create a backup image of BitLocker-protected drives.
    You can still do sectory-by-sector copies which require more space and time to create and restore.
  2. You cannot boot natively from a VHD if this VHD is placed on a BitLocker-protected drive.
    My laptop has only a single hard drive and you can can’t boot to VHD on network or removable drives.
  3. If your laptop is not equipped with a TPM you need to insert a USB stick every time before you can boot your laptop.
