Simple ubuntu backup to S3

Posted on Mon 22 November 2010 in Tech

After browsing the web for ages to find a decent solution to backup my server to amazon s3 I finally came across one and I'm just throwing it up here.

Reqs:

So basically all I need it to do was backup my sites(filesystem and mysql databases) and some config for lighttpd.

Implementation:

The post I'm basing this off is here

  1. Install automysqlbackup using apt

sudo apt-get install automysqlbackup

  1. Run automysqlbackup as root(just to give it a test)

sudo automysqlbackup

  1. Double check the databases are being backed up you should see daily, weekly and monthly under /var/lib/automysqlbackup with the appropriate databases.

  2. Now use this script to backup all the specific folders you want.

#!/bin/sh
 # Export some ENV variables so you don't have to type anything
 export AWS_ACCESS_KEY_ID=
 export AWS_SECRET_ACCESS_KEY=
 export PASSPHRASE=
 # Your GPG key
 GPG_KEY=;
 # The source of your backup
 SOURCE=/
 # The destination
 # Note that the bucket need not exist
 # but does need to be unique amongst all
 # Amazon S3 users. So, choose wisely.
 DEST=s3+http://
 # The duplicity command and options
 duplicity
 — encrypt-key=${GPG_KEY}
 — sign-key=${GPG_KEY}
 — volsize=250
 — include=/var/www
 — include=/home
 — include=/etc/lighttpd
 — include=/var/lib/automysqlbackup
 — exclude=/**
 ${SOURCE} ${DEST}
 # Reset the ENV variables. Don't need them sitting around
 export AWS_ACCESS_KEY_ID=
 export AWS_SECRET_ACCESS_KEY=
 export PASSPHRASE=

  1. Add your own specific access key stuff and give it a test

  2. Then add it to a cronjob

0 0 * * * /usr/sbin/automysqlbackup && /root/s3_backup
