Quick help needed in the Shell Script

i have a doubt here--

I have to take backup of all the files inside directory dir(logs,tmp,corefiles) at the location $BackupLocation.i should take the backup of logs,tmp,corefiles inside the $BackupLocation directory and then remove the files and touch the files inside the directory dir(logs,tmp,corefiles).
