Hi,

We are trying to schedule a NTBACKUP job for backuping the Exchange 2003

When we running the script manually, the backup is completed succesfully but
when we schedule it, we have an error message

Error message :
Backup Status
The operation was not performed because the specified media cannot be
found.


Script used:
C:\WINNT\system32\NTBACKUP.EXE backup "@E:\Exchange.bks" /n "Media_LuS1" /d
"Label_Exchange_LuS1" /v:no /r:no /rs:no /hc:off /m normal /j
"Backup_Exchange_LuS1" /l:s /f "E:\LundiS1\Backup_Exchange.bkf"

We also use this command to make sure that the network drive is never
disconnected.
net config server /autodisconnect:-1

Thanks for your help

Create the following batch file, then invoke it via the Task Scheduler:
@echo off
echo %date% %time% %UserName% >> c:\test.txt
cacls e:\LundiS1 1>>c:\test.txt 2>>&1
dir E:\LundiS1 1>>c:\test.txt 2>>&1
copy /y %comspec% E:\LundiS1\ 1>>c:\test.txt 2>>&1
C:\WINNT\system32\NTBACKUP.EXE backup "@E:\Exchange.bks" /n "Media_LuS1" /d
"Label_Exchange_LuS1" /v:no /r:no /rs:no /hc:off /m normal /j
"Backup_Exchange_LuS1" /l:s /f "E:\LundiS1\Backup_Exchange.bkf"

echo %date% %time% >> c:\test.txt

Now examine the log file c:\test.txt. It will probably tell you what's
wrong. If not then post its content in your reply.
 
We found the solution !

The scheduler is not working correctly when a network drive is used....

So we used the UNC instead of the share name and all is working fine

Thanks
 
The scheduler actually works correctly both for mapped and for UNC drives.
However, drives mapped in the foreground are *not* visible to scheduled
tasks because they operate in an independent context. Furthermore, if nobody
is logged on then there will be no drives mapped to a network share. Using
UNC mapped shares is the correct solution.
 
I am having the same problme but I do not understand the solution. I am using
a mapped network drive. How do I use UNC? What is the problme with a mapped
drive (this used to work but has suddenly stopped working)?

Thank you in advance,

Please start your own thread and describe exactly what you're doing, in
particular:
- The account you use for the job
- If it is the same as a current foreground account
- The exact command you use
- The contents of the ntbackup log file
 
Dear Pegasus,

Thank you for replying so promptly.

I would start a new thread if I could. When I click on new then question, an
exclamation point shows up in a yellow star next to the curor (I allowed
popups for the site) so I cannot start a thread.

Unfortunately, I do not know the answers to any of your questions. I am an
administrator on the machine and that is how I logon. I do not use any
command. I use the Backup Utility that came with Windows Server 2003. I would
not know where to find a log file. The report always reads:

Backup Status
The operation was not performed because the specified media cannot be found.

Best wishes,
/s/ Alan Auerbach
