Exchange 2003 backup using ntbackup.exe

HI,

we are trying to troubleshoot a problem with the exchange2003 backup not consistently running daily, after the file storage location has been changed.

previously we had a scheduled task running using the following "run as" line (i think only the last part pointing to U: was edited since we changed the backup "storage" location from being on a local folder in the exchange server to this intended remote server exchangebu mapped folder):

C:\WINDOWS\system32\ntbackup.exe backup "@C:\Documents and Settings\Administrator.TEXASMEDCLINIC\Local Settings\Application Data\Microsoft\Windows NT\NTBackup\data\Exchsvr Backup.bks" /n "Daily Backup.bkf created 2/21/2005 at 8:07 AM" /d "Set created 2/21/2005 at 8:07 AM" /v:no /r:no /rs:no /hc:off /m normal /j "Exchsvr Backup" /l:s /f "U:\Daily Backup.bkf""

however now 5 out of 8 days we get the following error message in the log located at:<C:\Documents and Settings\Administrator.TEXASMEDCLINIC\Local Settings\Application Data\Microsoft\Windows NT\NTBackup\> :
Backup Status
  The operation was not performed because the specified media cannot be found..

checking the application even log shows this event id :8017
NTBackup error: 'The operation failed. Consult the Backup Report for more details.'

after reviewing the scheduled task line we THINK the /rs switch should be set to YES but for now we are tryign to run a batchfile using net use to map to the u drive 2 minutes before the backup is scheduled to see if the that solves the 'media not available" problem.

if anyone has any suggestions how else we can go about solving this, i'd greatly appreciate it!
Thanks in advance!

hit start then run type in ntbackup.exe you will start up the NTbackup application, from the gui you can setup new scheduled jobs, will be easier than running it from the command line.
