Hi I am getting incorrect command line error when I type this code,
DECLARE @Result int
DECLARE @cmd varchar(200)
set @cmd = '"\\localhost\7-Zip\7z.exe" C:\test\servername_dbzip_testdb-20160712.zip c:\test\dumps'
print @cmd
EXEC @Result = xp_cmdshell @cmd

Is your server really called 'localhost'? I know that works for default SQL Server instances, but I'm not sure about UNC paths.

yeah when I type \\localhost in windows explorer and because I have shared 7-zip folder, I can browse this path and its my local machine where I am admin

Have you tried running the command in the command-prompt directly? As opposed to through xp_cmdshell, I mean.

You have not included 'e' (Extract). See info here.

Gus is right: make it work natively first, then plug into T-SQL.

Thanks Phil and GsSquad it worked, When I added some switches.

set @cmd = '\\localhost\7-Zip\7z e C:\test\servername_dbzip_testdb-20160712.zip -oc:\test\dumps *.bak -y'
