Windows Backup Tape Overwrite Problem

[Chaplain Doug]

Windows 2000 Server. I have scheduled 4mm tape backups to
happen each day using Windows Backup. My problem is that
the tape being used normally has data on it already and I
just wish to overwrite. However, when the backup job
kicks off it immediately bombs and puts a message in the
log:

The operation was not performed because no unused media
was available.

How do I tell Windows Backup to write over the data on the
tape? Obviously I need this to happen without a prompt as
the job is running during off hours. When I do the backup
manually I get a couple of prompts about overwriting the
tape, I answer "Yes" and the job completes. Thanks for
the help.

Hi,

Please refer KB314844

and you try these steps manually

1) goto schedule job and right click on the scheduled job eg "server" and
goto properties, the command for run is
C:\WINNT\system32\NTBACKUP.EXE backup "@C:\Documents and
Settings\Administrator\Local Settings\Application Data\Microsoft\Windows
NT\NTBackup\data\server backup.bks" /n "Media Created 6/24/2003 at 11:00
pm" /d
"Set created 6/24/2003 at 11:00 pm" /v:yes /r:no /rs:no /hcn /m normal /j
"server
backup.job" /l:s /p "dlt"

2)remove /n "Media Created 6/24/2003 at 11:00 pm" and add /um switch at
the last of the command
now the new command string for run is
C:\WINNT\system32\NTBACKUP.EXE backup "@C:\Documents and
Settings\Administrator\Local Settings\Application Data\Microsoft\Windows
NT\NTBackup\data\server backup.bks" /d "Set created 6/24/2003 at 11:00 pm"
/v:yes
/r:no /rs:no /hcn /m normal /j "server backup.job" /l:s /p "dlt" /um

Note : the time and media created values are just for example
