DESTFILE="$BACKUP_DST/$NOW.tgz"

#
# Upload a file to Dropbox.
# $1 = Source file
# $2 = Destination file.
function dropboxUpload
{
	#
	# Code based on DropBox Uploader 0.6 from http://www.andreafabrizi.it/?dropbox_uploader
	LOGIN_URL="https://www.dropbox.com/login"
	HOME_URL="https://www.dropbox.com/home"
	UPLOAD_URL="https://dl-web.dropbox.com/upload"
	COOKIE_FILE="/tmp/du_cookie_$RANDOM"
	RESPONSE_FILE="/tmp/du_resp_$RANDOM"

    UPLOAD_FILE=$1
    DEST_FOLDER=$2

	# Login
	echo -ne " > Logging in..."
	curl -s -i -c $COOKIE_FILE -o $RESPONSE_FILE --data "login_email=$DROPBOX_USER&login_password=$DROPBOX_PASS&t=$TOKEN" "$LOGIN_URL"
	grep "location: /home" $RESPONSE_FILE > /dev/null

	if [ $? -ne 0 ]; then
		echo -e " Failed!"
		rm -f "$COOKIE_FILE" "$RESPONSE_FILE"
		exit 1
	else
		echo -e " OK"
	fi

	# Load home page
	echo -ne " > Loading Home..."
	curl -s -i -b "$COOKIE_FILE" -o "$RESPONSE_FILE" "$HOME_URL"

Save the script as “dropboxbackup.sh”, chmod +x it and run ./dropboxbackup.sh.

Add a Cron Job

crontab -e
# m h  dom mon dow   command
0 0 1 * *       /bin/bash /root/dropboxbackup.sh

To change the default editor to nano

yum install nano
nano ./bashrc

add this to the file

export EDITOR=nano

It will take effect next time you login.
