Why match zero or more characters in  /.*rrd$/ when  /rrd$/ would match the same thing with less work?    Perhaps you meant  /\.rrd$/? 



        $cmd = qq|$mv resize.rrd $logsdir/$rrd|;
        print "\tRenaming resized file, executing $cmd\n";
        system($cmd) == 0 or die "Could not execute $cmd:$!\n";

Why not just use Perl's built-in rename function? 

        print "\tRenaming resized file, executing $cmd\n";
        rename 'resize.rrd', "$logsdir/$rrd" or die "Could not rename 
+resize.rrd:$!\n";
