Useful Backup Scripts

Installation

Clone this repo somewhere onto your EC2 instance. You may need to chmod the scripts so that they are executable;

chmod +x aws-backup/*.sh

If you want to use the db-backup script, you will need to create a .conf file as per /example.conf.

Usage

Backup Database

Given the correct credentials, this script should back up all tables on the database and store them in s3.

The db-backup.sh script requires one parameter (the config file) e.g.

. db-backup.sh example.conf

Backups are kept on the server for as long as the 'lifespan' config variable.

Cron

Most likely you'll want to schedule these backups using crons like so;

# Backup the database every 6 hours
0 */6 * * * /path/to/repo/db-backup.sh

Backup EC2 Instance

You can backup the EC2 instance by running the ebs-backup.sh script e.g.

. ebs-backup.sh

Cron

# Take snapshots of the server every hour
0 * * * * sudo /path/to/repo/ebs-snapshot.sh
