help on this command, creating ..

1. The problem statement, all variables and given/known data:

Description

Bsafe The command creates a backup directory of each month at the command line (arguments of the script). The names of directories to copy will always be specified for the home user. To save copies of the script uses a specific directory, now called the backup directory. If the backup directory does not exist, the script should create it. Within the backup directory, the script should create a directory for each backup done (use a different name every time). Within this directory (the copy of the instant), each directory passed as argument of the script should be copied, including sub-directories and files, preserving dates and times of access and modification of them. Of course, the backup directory should not be copied into itself.

2. Relevant commands, code, scripts, algorithms:

3. The attempts at a solution (include all code and scripts):

Code:

#!/bin/bash
DIR=base/path/of/your/backup/dir/$(date +%y%m)
[ -d "$DIR" ] || mkdir "$DIR"
for D in $@ # gets the arguments of the command line
do
    cp -av ~/"$D" "$DIR/$D"
done

the command, need create a backup file/directory if not exist at /home, and inside of that directory, each copy safe(the command), create a subdirectory inside of backup, example: backup1, backup2...((each directory passed as argument of the script should be copied, including sub-directories and files, preserving dates and times of access and modification of them)).
