Send your Mysql backups to S3
A simple backup script for Mysql and S3 with incremental backups.
It's all based on Paul Dowman's blog post: http://pauldowman.com/2009/02/08/mysql-s3-backup/, so read this first.
Configuration
To use incremental backups you need to enable binary logging by making sure that the MySQL config file (my.cnf) has the following line in it:
log_bin = /var/db/mysql/binlog/mysql-bin
The MySQL user needs to have the RELOAD and the SUPER privileges, these can be granted with the following SQL commands (which need to be executed as the MySQL root user):
GRANT RELOAD ON *.* TO 'user_name'@'%' IDENTIFIED BY 'password';
GRANT SUPER ON *.* TO 'user_name'@'%' IDENTIFIED BY 'password';
Usage
Create a YAML config file:
mysql:
# Database name to backup
database: muffins_development
# Mysql user and password to execute commands
user: root
password: secret
# Path to mysql binaries, like mysql, mysqldump (optional)
bin_path: /usr/bin/
# Path to the binary logs, should match the bin_log option in your my.cnf
bin_log: /var/lib/mysql/binlog/mysql-bin
s3:
# S3 bucket name to backup to
bucket: db_backups
# S3 credentials
access_key_id: XXXXXXXXXXXXXXX
secret_access_key: XXXXXXXXXXXXXXXXXXXXXX
# Optional timeout in seconds
timeout: 30
Create a full backup:
mysql_s3_backup -c=your_config.yml full
Create an incremental backup:
mysql_s3_backup -c=your_config.yml inc
Restore the latest backup (applying incremental backups):
mysql_s3_backup -c=your_config.yml restore
Restore a specific backup (NOT applying incremental backups):
mysql_s3_backup -c=your_config.yml restore 20091126112233
Running the specs
Create a config file in config/test.yml
