How do I back up application code?

Background

You want to manually save your application code.   Perhaps you have an EC2 instance where you want to save your application code to an S3 bucket before the instance is terminated.

Answer

You can use the sample Bash code below to create a RightScript that will upload the contents from a specified directory to an S3 bucket.  Simply add it to your Server/ServerTemplate and run it as an operational script to backup your application code.

Note: This script assumes that you have s3cmd installed. (See How do I install s3cmd?)

#/bin/bash
#
# Package content of application directory and upload it to s3
# Caution: Will overwrite any existing S3 files without warning!
#

export AWS_SECRET_ACCESS_KEY=$AWS_ACCESS_KEY
export AWS_ACCESS_KEY_ID=$AWS_ACCESS_ID

if [ -d "$APP_DIR" ]; then
        cd $APP_DIR
        tar czf $APPLICATION_NAME *
        s3cmd put $BUCKET:$APPLICATION_NAME $APPLICATION_NAME
        rm $APPLICATION_NAME
        logger -t RightScript "Uploaded $APPLICATION_NAME to S3 bucket $BUCKET"
        exit 0

else
        echo "Error entering directory $APP_DIR"
        echo "Aborting"
        exit 1

You will need to define values for the following inputs:
