With the above provided script(the one written by itkamaraj) you ask the user for backup destination directory and move the file there, this is not needed and probaly will confuse the user.

You can just easily ask them for destination(as you did) and create the archive there

Example:

Code:
while true
do
    echo "Choose an option"
    echo "1. Backup"
    echo "2. Restore"
    echo -en "\nEnter your choice : "
    read choice
    
    case $choice in 
        
        1)     echo -n "Enter the backup filename: "
            read filename
            echo -n "Enter the Directory Name : "
            read dir_name
            tar -czvf filename $dir_name/$filename.$(date +%Y%m%d)-backup.tar.gz
            echo "$filename moved successfully to $dir_name"

        2)  echo -n "Enter the destination (directory name) : "
        read dir_name
            echo -n "Backups in $dir_name:"
            ls -al $dir_name
            echo -n "Enter the filename to restore : "
            read filename
            tar -xzvf $filename $dir_name

        *)    echo "Choose the Correct choice (1/2)"
    esac
done

On the backup "log" the -v flag of the tar command shows every file that goes into the archive example:

Code:
[root@yorkfield Downloads]# ll
total 0
-rw-r--r--. 1 root root 0 Jun  5 00:50 1
-rw-r--r--. 1 root root 0 Jun  5 00:50 2
-rw-r--r--. 1 root root 0 Jun  5 00:50 3
-rw-r--r--. 1 root root 0 Jun  5 00:50 4
-rw-r--r--. 1 root root 0 Jun  5 00:50 6
[root@yorkfield Downloads]# 
[root@yorkfield Downloads]# tar -czvf test.tar.gz ./*
./1
./2
./3
./4
./6

Menu?? Menus are for the weak.
Are you required to use a menu?

You can better use the power of the command-line by exposing everything to command-line arguments and switches.

Others have made good points about file naming, so ignoring that part, here's my contest entry:
Code:
#!/bin/sh
function error_exit() { echo "ERROR: $*" 1>&2; exit 1; }
usage()
{
    cat <<EOF
Usage:
    ${0##*/} [switches] {b|r}

Arguments:
    b - Backup your home directory
    r - Restore your home directory
EOF
    exit 0
}
CMD= STORAGE=someplace
while test $# -gt 0; do
    case "$1" in
        b|B|backup)  CMD=cfj ;;
        r|R|restore) CMD=xfj ;;
        -h|-help|--help)  usage                   ;;
        -*)  error_exit "Unknown switch \"$1\""   ;;
        *)   error_exit "Unknown argument \"$1\"" ;;
    esac
    shift
done

test -z "$CMD"  &&  usage
cd
tar $CMD $STORAGE/home.tbz .
