To be able to use || and && in conditions, you have to use the double square brackets:

if [[ $i == backup || $i == $filename ]] ; then

The compare operator is = (as defined in POSIX). But == works on some shells as well. Something like this should work:

if [ $i = backup ] || [ $i = $filename ] ; then

You should quote $i in "". Otherwise you get syntax errors for filenames with blanks.
