Off the top of my head, you could do it like this:
push @{$Conf{BackupFilesExclude}{'*'}}, '/dir1', '/dir2', '/dir3';
push @{$Conf{BackupFilesExclude}{'/'}}, '/dir4', '/dir5', '/dir6';
You can also use an array instead of listing the new entries:
push @{$Conf{BackupFilesExclude}{'*'}}, @newstuff;
Untested, so the syntax may not be perfect...
