Call via crontab on whatever schedule suits you; keep n full mysql Percona xtrabackups of your mysql database, with binary logs applied. Also does a full mysqldump that can then have the binary logs applied to restore to a point-in-time backup via the binlogs. Copy all of this (backup, mysqldump, binlogs) to S3.

	#!/bin/bash
	#
	# Carries out a full mysqldump, calls percona-xtrabackup and then
	# copies the sql dump, the percona backup and your mysql bin logs
	# to S3 using s3cmd http://s3tools.org/s3cmd
	#
	# TODO: extract out the S3 backup stuff to make it optional, and so
	# other s3 programs can replace the s3cmd call.
	# TODO: the if [ $? == 0 ] alert blocks should be a function
	# TODO: make the if [ $? == 0 ] if [ $? != 0 ] more consistent - test
