mysql-dropbox-auto-backup

Dump MySQL databases, compress them and upload to Dropbox. Backups are kept for 7 days.

Overview

mysql-dropbox-aut-backup is a simple shell script that will use mysqldump to dump all of your MySQL databases, omitting any that you specify, add them to a compressed tarball, and upload them to Dropbox. By defauly it will also dump the MySQL user table unless you tell the script not to in mysql-drop-backup.sh. The script makes use of the Dropbox-Uploader project by Andrea Fabrizi and mysql-dropbox-backup project by Barnaby Knowles Run it as a daily cron job to keep 7 days of backups. On each run it will try to delete the backup taken 7 days ago.

Requirements

cURL
A Dropbox account

Most Linux systems will come with cURL and OpenSSL installed. Dropbox gives away 2GB of storage for free.

Installation

First, clone the repository using git (recommended):

git clone https://github.com/wcaaan/mysql-dropbox-auto-backup.git

Place your script directly in home directory.

Configuration

Edit mysql-dropbox-backup.cnf to add your MySQL connection details.

Edit the top section of mysql-dropbox-backup.sh if you wish to change MySQL config file location. By default it is set to the current directoy. edit the list of ignored databases if you wish. You can also choose whether to dump the MySQL user table or not.

Edit the path if necessary, by default it is set to the current directory.

Usage

The first thing you should do is give the execution permission to the dropbox_uploader.sh script and run it:

 $ chmod +x dropbox_uploader.sh
 $ ./dropbox_uploader.sh

The first time you run dropbox_uploader.sh, you'll be guided through a wizard in order to configure access to your Dropbox. This configuration will be stored in ~/.dropbox_uploader.

Once the dropbox is configured give the execution permission to mysql-dropbox-backup.sh and simply run it:

$ chmod +x mysql-dropbox-backup.sh
$ ./mysql-dropbox-backup.sh

Ideally this script should be run as a daily cron job. After uploading the present backup, it will attempt to delete the backup from 7 days previous, so that only one week of backups are retained. The script is quite verbose and will output which databases were backed up and the names of any files generated etc.

Simply download the desired file from your dropbox, extract it and the SQL files will be available to restore within the resulting directory.
