For sake of demonstration:

    def restoreDevice(self, deviceId, closeTime = time()):
        self.logon()
        try:
            lst = self.getLastUpdatedDevice(deviceId)
            lastUpdated = lst[0]
            incidentId = lst[1]
            print 'L', lastUpdated, 'I', incidentId
            self.restore(incidentId, lastUpdated)
        except:
            pass
        else:
            print "couldn't find incident"
