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

I use Namecheap.com as a registrar, and they resale SSL Certs from a number of other companies, including Comodo.

These are the steps I went through to set up an SSL cert.

Purchase the cert
