   If by "not taking resoures", you meant not to take CPU time as much as   
   possible, then you can start the batch file in another command processor   
   process as a low priority process using START /LOW. e.g.   
      
   @echo off   
   setlocal   
   if not "%InLowPriority%" == "" goto start   
   set InLowPriority=1   
   start "Backup Batch" /b /low /wait cmd /c %0 %*   
   goto :eof   
   :start   
   rem put backup batch code here   
   rem   
   rem e.g.   
   rem copy sourcefile z:\destfolder   
   rem contig z:\destfolder\sourcefile   
      
   Note that running a process in low priority only make use less CPU   
   processing share. It doesn't make it use less CPU time. i.e. it'll always   
   run at full speed whenever the system give CPU time to it.   
      
   If you want to make a process use less CPU time and not run at full speed,   
   you'll have to use third party file copying tools that can limit its file   
   copying speed. Or a utility that can limit a process CPU usage. e.g. BES but   
   it can't be automated by command line.   
      
   Also be aware that the CPU usage of a file defragmentation process can not   
   be altered since it is handled separately by the kernel. It always runs at   
   full speed and can not be limited by tools like BES.
