see this post,

1) has this worked in the past ?
2) Wat has changed ?
3) Does a manual run have issues ?
Mostly errors are caused by permissions of the task scheduled, and the context of the user.
4.Does this script create a log?  If not, could you change it so it does create a log - writing to the log every so often.  Then you could look at the log and see the last portion that ran successfully.
5.Notmally these error msgs will be generated because the script may try to insert nulls into fields that were not setup to allow null values

also ref  these stuffs,

The following are the entries in the log file.
GISCOPY.job" (GISCOPY.bat)
      Started 8/3/2008 6:00:01 PM
"GISCOPY.job" (GISCOPY.bat)
      Finished 8/3/2008 6:05:24 PM
      Result: The task completed with an exit code of (b).

I added a dumby file for testing and ran the script manually.  The file copied.  Then I renamed the dumby file and tried running the script again.  Again the dumby file copied.  It does appear that the script is running using the Task Scheduler.  What I noticed in the Robocopy log is that some of the files cannot be copied because they are in use.  Could this be the reason for the (b) exit code?

Do you know what the /c switch stands for?

/copy:<CopyFlags>
 Specifies the file properties to be copied. The following are the valid values for this option:

D Data
A Attributes
T Time stamps
S NTFS access control list (ACL)
O Owner information
U Auditing information
The default value for CopyFlags is DAT (data, attributes, and time stamps).

I checked the Robocopy commands and I have the /Copy:Dat configured.  After more testing, it appears that the error is a result of open files not copying to the new directory.  I may need to find another solution besides Robocopy.  

you have to go for a open file agent backup solution...

Do you have any suggestions?  We are using Netbackup for backing up files, but I don't have a solution that I can use with a batch file to backup and restore files over the night.

I am not comfortable doing the open file backup using script.... I would better suggest you to have a deep look in to the Netbackup and utlizise its own backup file agent... I am sure Netback supports customized backup script

Great information! Thanks.
