Why should I use BitLocker in Windows Server 2012?

BitLocker is available in all Windows Server 2012 versions (plus Windows 8 Enterprise and Pro) to secure system and user files. It has an easy installation process and supports multiple access methods. Plus, Microsoft says BitLocker encryption has a small performance penalty at only 10% or less.

What server requirements are needed to use Windows BitLocker?

There are no excessive or unusual requirements to use BitLocker in Windows Server 2012. These are the three requirements, all of which are relatively easy to meet: a server with a trusted module platform to ensure the system's integrity, an evaluation of the system's BIOS and two partitions provided by the encrypted drive.

What are the best ways to use the BitLocker recovery options?

There are two recovery options in Windows Server 2012: Suspend or Decrypt. If you want to stop using BitLocker all together, it's best to use Decrypt, which decrypts all of the data and disables BitLocker. It's also good to know that some software upgrades may require drives to be suspended or decrypted before installation to prevent any BitLocker interaction issues.
