Question

ntbackup script adding an "s" to a filename instead of generating a log!

Asked by: shattuck007

I have a batch file that calls up ntbackup and creates a backup file in a new folder created using the date variable:

It uses this command line:

MD U:\backup02\BACKUP_%Date:~-4,4%%Date:~-10,2%%Date:~-7,2%

C:\Windows\System32\ntbackup.exe backup "@c:\backup\backup02.bks" /f U:\backup02\BACKUP_%Date:~-4,4%%Date:~-10,2%%Date:~-7,2%%\backup.bkf /m normal

This works great, and creates a backup.bkf file under (for today as an example) U:\backup02\BACKUP_20091019\backup.bkf

Now, I am trying to get ntbackup to generate a summary log file by adding /l:s in the command line.

C:\Windows\System32\ntbackup.exe backup "@c:\backup\backup02.bks" /f U:\backup02\BACKUP_%Date:~-4,4%%Date:~-10,2%%Date:~-7,2%%\backup.bkf /m normal /l:s

What this does instead is generate a file under the mapped drive with an "s" appended to it!
example:  "U:\backup02\BACKUP_20091019s" is now created instead of backup.bkf being created under U:\backup02\BACKUP_20091019\backup.bkf

What have I done wrong here? I have tried putting the /l:s switch at a different spot in the command, and it causes the backup not to execute at all.

thanks!

Try this:

C:\Windows\System32\ntbackup.exe backup "@c:\backup\backup02.bks" /l:s /m normal /f c:\backup02\BACKUP_%Date:~-4,4%%Date:~-10,2%%Date:~-7,2%%\backup.bkf  

 

by: efusionPosted on 2009-10-19 at 10:41:40ID: 25607276

oh yeah but change the C: to U: in your case:

C:\Windows\System32\ntbackup.exe backup "@c:\backup\backup02.bks" /l:s /m normal /f U:\backup02\BACKUP_%Date:~-4,4%%Date:~-10,2%%Date:~-7,2%%\backup.bkf  

 

by: shattuck007Posted on 2009-10-19 at 11:13:55ID: 25607596

I had tried placing /l:s in that location before and it didn't work. I just tried it again and it wouldn't kick off the backup process. Actually it would pull up NTbackup then immediately exit out.

 However, I then removed all " marks from the command line and stuck the /l:s switch where you suggested .... and it appears to now be working! Hooray!

You've got an extra % at the end btw, might be just yuor copy/paste here:

C:\Windows\System32\ntbackup.exe backup "@c:\backup\backup02.bks" /f U:\backup02\BACKUP_%Date:~-4,4%%Date:~-10,2%%Date:~-7,2%[REMOVED WAS HERE]\backup.bkf /m normal /l:s

 

by: shattuck007Posted on 2009-10-20 at 07:41:32ID: 31643007

removing "'s and relocating the /l:s switch seemed to do the trick.
