	Secure Backup and Restore uses a Publish and Subscribe key to publish
	the current backup / restore state.
 
	The key is a system key so the category to be used when subscribing is KUidSystemCategoryValue
	The key to be used is KUidBackupRestoreKey.
	The value is a bit-wise OR of a TBURPartType value and a TBackupIncType value
	This means that a normal state (i.e. non-backup or restore) is EBURNormal | ENoBackup but
	If the key has not been set (i.e. == 0) then no backup or restore is in progress either
