sunckell,

The following code ...

   
mkpath(['/export/home/backup/$hostname/$home_users'], 0, 0666);

does not interpolate. You are creating a path called /export/home/backup/$hostname/$home_users. Change the single quotes ' to double quotes ". That may be the problem.

Another problem may arise after you fix this. That is the fact that you are using $homeusers. You have declared @home_users. In this case I think that you mean to use $home_user

my @home_users< = split " ", $home_list;
foreach my $home_user< (@home_users) 
{
  #Do you mean $home_user here? because $home_users is not declared.
  mkpath(['/export/home/backup/$hostname/$home_users'], 0, 0666);
