I need a solution
There are BE 2012 and SBS server which includes Exchange 2007 in our production network and according to a schedule full backup of mail database should be done twice every week. Usually everything is ok, however, sometimes, backup process is interrupted by error and since the moment when such error occurred backup cannot be done any more because all following jobs finish with this error. Only one thing can help which is restarting Exchange service called "store.exe". After restarting backups can be done successfully again. This is information about error:
