input: [Option] -n [Explanation] 
output: No overwriting of backup files, append log file. If this option is selected and the tag data is already backed up in the output directory an additional copy of it is created. This is useful if you are creating a first backup with several runs of tagbkup. If you are creating a second backup of updated tags it will start creating files with _001, _002 and these files are never restored when running a restore.
