I tried to take a back up of my SPS using command line but it is not responding at all (it neither gives an error nor shows any trace in task manager). Though I am able to take the back up using the GUI that gets invoked if in the command line I type only spsbackup (i.e., C:/>spsbackup).

I used the following line in my command prompt:

c:/> spsbackup /all /portal http://MySPSServer /service sitedbs /file c:\spsbackup\backup /overwrite

Has anybody tried to get a backup using this pure command line SPSBACKUP.exe tool without the GUI? Please help.
