Linux Avoid overwriting backup file when multiple entries need to replace in one file input from another

I have been working on script in which search and replace the multiple pattern.

1. read the multiple pattern from input file ParamMapping.txt(old_entry|New_entry) and passing this values one by one to
2. read input from
search files and based upon parameter(search and replace) from generates FileList.lst
for each files in FileList.lst it takes backup(.bkp) and replace the string and update in to new file.

Issue when a same file contain multiple string defined in ParamMapping.txt which is going to be replace, it also replaces the entry in .bkp files which I have to avoid.
I am not able to figure out how to avoid overwriting .bkp file when multiple entries need to replace in one file.

PFA files.

file execution :

./ ParamMapping.txt

Any suggestions will be helpful.....Smilie
