Unable to take the backup of ServiceDesk Plus

Hi,

We have the below error two days in a row, both front\back end servers appear to have ample disk space despite what the error suggests. The logs I found in the BIN directory do not give any clues. Can anyone suggest a solution or next troubleshooting steps?

java.io.IOException: There is not enough space on the disk at java.io.FileOutputStream.writeBytes(Native Method) at java.io.FileOutputStream.write(Unknown Source) at sun.nio.cs.StreamEncoder$CharsetSE.writeBytes(Unknown Source) at sun.nio.cs.StreamEncoder$CharsetSE.implWrite(Unknown Source) at sun.nio.cs.StreamEncoder.write(Unknown Source) at java.io.OutputStreamWriter.write(Unknown Source) at java.io.BufferedWriter.flushBuffer(Unknown Source) at java.io.BufferedWriter.write(Unknown Source) at java.io.Writer.write(Unknown Source) at com.adventnet.servicedesk.tools.SDBackUp.dumpTableUsingCriteria(SDBackUp.java:985) at com.adventnet.servicedesk.tools.SDBackUp.dumpTable(SDBackUp.java:767) at com.adventnet.servicedesk.tools.SDBackUp.startBackup(SDBackUp.java:343) at com.adventnet.servicedesk.tools.SDBackUp.process(SDBackUp.java:94) at com.adventnet.servicedesk.setup.task.ScheduledBackupTask.executeTask(ScheduledBackupTask.java:88) 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)

Thank for your help in advance,
