bash variable's if then statement not evaulating correctly

I have written a script that should tell me the number of lines from the nightly network backups. It should be 109 and if it is the same I get success email and if it is not the same I get a failure email. I have added 2 fake host to one of the files that is checked in the script below to see if it will fail. The if then statement simply does not work. If I make the amount of hosts in the file's 'confirm-backed-up' and 'backed-up' different it makes no difference and it just uses the very first if then statement regardless if they are different or not.

At the end you can see I ran the wc -l on the two files and they are different however the script runs and gives me the first then of the if, then: backed-up and confirm-backed-up match. It goes the other way also - if they are the same I just get the first if then statement - which at first made me think it was working until I checked it with the files not matching in number.
