Google Drive MySQL Dumper

Small script which exports a MySQL database to a file and uploads it to Google Drive.

By default, the script works on a 14 day retention policy. That is, local and remote backups are kept for up to 14 days, any local backup files the script finds in the backup directory will be gzipped before the newest backup is exported and uploaded.

Requirements

Requires the gdrive command line utility for Google Drive.

Installation

  1. Download the gdrive utility from its GitHub page and follow its installation guide.

  2. Clone this repository

  3. Make the db-dump.sh script executable, and link it somewhere it can be called from any directory e.g:

    $ chmod +x /path/to/db-dump.sh
    $ sudo ln -s /path/to/db-dump.sh /usr/local/bin/db-dump
  4. Set up your db-dump.conf file, either manually by copying db-dump.conf.dist, or by typing db-dump config at the command line:

    $ db-dump config
    Generating config file...
    Enter Database Name: mydatabase    
    Enter Google Drive Folder ID: abc123def456
    Config file generated.
  5. Run the script

    $ db-dump
    Uploading /var/spool/db-dump/mydatabase-2016-11-09_17:09:51.sql

Configuration

The following options must be set and do not have default values:

Option Description
db_name Name of the database to export
gdrive_folder_id Google Drive folder ID where files get uploaded

The following options do have default values and can be tweaked as desired:

Option Description Default
date_format Date format for dates appended to export files %Y-%m-%d_%H:%M:%S
dump_dir The local directory where export files will be stored /var/spool/db-dump
retention_days The number of days to retain export files 14
mysql_opts Options to pass to mysqldump e.g: "-uroot" (None)

Options can be changed in the main db-dump.conf file or can be overridden on a per user basis by creating a config file within your home directory: $HOME/.config/db-dump.conf

Options can also be changed by passing a config file as the first argument to the script. This allows the script to be used with different databases and configurations:

db-dump /path/to/my/db-dump.conf

Automation

The easiest way to automatically run the script over a given interval is to link it into one of the /etc/cron.* directories, e.g:

sudo ln -s /path/to/db-dump.sh /etc/cron.daily/db-dump

The above command will cause the script to be run once every 24 hours.
