The string is being interpolated again, so you need \ x4. 
$filename_b = "c:\\\\abc.log";

but then the eq won't work.
You could also use the magic of qr// 
$filename_a = "c:\\abc.log";
$filename_b = "c:\\abc.log";
$filename_b_re = qr/c:\\abc.log/;

print "Are they equal ? : ";
print $filename_a eq $filename_b ; # output is 1

print "\n";
print "Do they match ? : ";
print $filename_a =~ /$filename_b_re/ ; # output is 1

Another option(prefered, at least by me) is to use / instead of \\ 
$filename_a = "c:/abc.log";
$filename_b = "c:/abc.log";
