We get the following error when the scheduled backup fails. What do I need to do to fix this?

Error Message java.io.IOException: The process cannot access the file because another process has locked a portion of the file at java.io.FileInputStream.readBytes(Native Method) at java.io.FileInputStream.read(Unknown Source) at com.adventnet.servicedesk.tools.SDBackUp.addEntry(SDBackUp.java:2224) at com.adventnet.servicedesk.tools.SDBackUp.zipDirectory(SDBackUp.java:2091) at com.adventnet.servicedesk.tools.SDBackUp.zipDirectory(SDBackUp.java:2064) at com.adventnet.servicedesk.tools.SDBackUp.endBackup(SDBackUp.java:788) at com.adventnet.servicedesk.tools.SDBackUp.process(SDBackUp.java:103) at com.adventnet.servicedesk.setup.task.ScheduledBackupTask.executeTask(ScheduledBackupTask.java:93) at com.adventnet.workengine.task.internal.TaskManagerImpl.executeTask(TaskManagerImpl.java:706) at com.adventnet.workengine.executor.internal.WorkFlowExecutor.executeStartingTask(WorkFlowExecutor.java:160) at com.adventnet.workengine.executor.internal.WorkFlowExecutor.executeWorkFlowTemplate(WorkFlowExecutor.java:115) at com.adventnet.workengine.executor.internal.WorkFlowExecutor.executeWorkFlow(WorkFlowExecutor.java:105) at com.adventnet.workengine.executor.internal.LocalWorkFlowExecutionHandler.execute(LocalWorkFlowExecutionHandler.java:67) at com.adventnet.workengine.internal.WorkEngineImpl$WorkFlowExecutorThread.run(WorkEngineImpl.java:931) at com.adventnet.workengine.service.ThreadPoolService$WorkerThread.run(ThreadPoolService.java:256) at java.lang.Thread.run(Unknown Source) 

Trouble shooting tips Please contact your DBA to update the following sql query 

update Task_Input SET OPERATIONAL_STATUS = 4 where SCHEDULE_ID = (select SCHEDULE_ID from schedule where SCHEDULE_NAME = 'BackupSchedule')

This sql query will stop your backup scheduling
