class CBaBackupSessionWrapper : public CBase;
CBaBackupSessionWrapper provides the APIs necessary to enable a backup or restore/install by allowing broadcast requests for some or all files to either remain untouched or have their locks released for an arbitrary period.
The class should be used by both code driving a backup/install and any engines that will hold files locks or may access files regardless of the presence of (non-system) client apps
