multi-threaded and implements the update option.

USAGE

$ backr [OPTIONS] --destination DESTINATION_PATH

FLAGS

   -a, --backup-all
         Backup all files found, overriding the regex. Because of this, it conflicts with the 
         regex option.

   -h, --help 
         Prints help information 

   -p, --progress
         Displays a progress bar during the backup.

   -V, --version 
         Prints version information

OPTIONS

-d, --destination <DESTINATION_PATH>
         The path to the location you want the data saved to.

-o, --output_file <output_file>
         Specifies the location that failed transfer paths are written to
         [default: "<DESTINATION_PATH>/backr_log.txt"]

-r, --regex <regex>
         Passes a regex to the program to only backup matching files
         and directories.
         [default: "Documents|Downloads|Movies|Music|Pictures|Videos"]

-s, --source <SOURCE_PATH>
         The path to the User directory you want to backup.
         [default: <CURRENT_WORKING_DIRECTORY>]

-t, --threads <NUM>
         Number of threads that will be used to backup files 
         [default: 2]

-u, --update <update>
         If this flag is set, backr will check the metadata of the
         source file and the already existing destination
         file, and will keep the newest one.
         [default: false]
