After install OpsMgr, You must Export the Encryption Key.
Only RMS can communcate with the database.
So to prevent RMS Failature we must backup the Encryption Key.
Copy SecureStorageBackup.exe to the installation directory for Operations Manager,
Also I recommend that copy SupportTools directory to the installation directory for Operations Manager.
.SecureStorageBackup.exe is included on the install media's SupportTools directory.
