Easy MySQL Backup

Packagist Downloads Code Coverage CodeFactor Code Coverage Coding Standards Static analysis Tests

About

This package allows you to backup a mysql database using mysqldump and then store it to a local file store (by default) or upload it to S3.

Installation

Install this package as a dependency using Composer.

composer require dutchie027/easymysqlbackup

You will also need to ensure you have a copy of mysqldump on the box this is hosted on. Also, if you want to use compression for backup and restore, you'll need gzip and gunzip.

Usage

The program will assume a lot of defaults if you don't have a config file, however it is highly suggested you create a config (see sample .ini below)

Backup Locally

#!/usr/bin/php
<?php

include_once 'vendor/autoload.php';

use dutchie027\EasyMySQLBackup\Backup;

# OPTION A: Create a new backup with "default" configuration set
$backup = new Backup();

# OPTION B: Create a configuration set using an .ini file
$backup = new Backup('/path/to/my.ini');

# Backup the database named "test". The location on the file system will be returned
$backup_file = $backup->createLocalBackup("test");

Backup and Upload to S3

#!/usr/bin/php
<?php

include_once 'vendor/autoload.php';

use dutchie027\EasyMySQLBackup\Backup;

# Because we're using S3, we have to instatiate it with a configuration set using an .ini file
$backup = new Backup('/path/to/my.ini');

# Backup the database named "test". The location on the file system will be returned
$backup_file = $backup->createLocalBackup("test");

# Upload the $backup_name file to the S3 Location "my-sql-backups/database.12345.sql.gz"
# NOTE: It will chop and assume the bucket name of "my-sql-backups". If the bucket "my-sql-backups" doesn't exist, it will create it
# NOTE 2: You can use multiple depts to the S3 key name
# NOTE 3: If you end the second parameter in anything other than .sql or .gz it will assume
# you are using a directory and append the name of the backup file to the end of the structure
$backup->s3->uploadFile($backup_file, "my-sql-backups/database.12345.sql.gz");

# Using the initial connection, remove the local file
$backup->purgeBackup();

Restore A Local File

#!/usr/bin/php
<?php

include_once 'vendor/autoload.php';

use dutchie027\EasyMySQLBackup\Backup;

# OPTION A: Create a new backup with "default" configuration set
$backup = new Backup();

# Restore the file '/backups/mydb.20220330162457.sql.gz' to the database named 'restoredb'
# Also, force the database to be dropped & recreated
$backup->restore()->restoreLocalBackup('/backups/mydb.20220330162457.sql.gz', 'restoredb', 1);

Restore From S3

#!/usr/bin/php
<?php

include_once 'vendor/autoload.php';

use dutchie027\EasyMySQLBackup\Backup;

# Because we're using S3, we have to give it a config file with our KVPs for S3 Access in them
$backup = new Backup('/path/to/my.ini');

# First download the file coredb.20220330162457.sql.gz from the bob-test bucket and put it in /tmp
# Assuming all runs well, store the local file name in the variable $buf
$buf = $backup->s3()->downloadFile('bob-test/coredb.20220330162457.sql.gz', '/tmp');

# Restore the newly downloaded $buf file to a new database 'core-restore' and force it to be dropped
# and created fresh
$backup->restore()->restoreLocalBackup($buf, 'core-restore', 1);

S3_ACL        = "private"

[database]

LOG_PREFIX    = 'easyMySQLBackup'

To-Do

  • Add routines to allow for removal of local backups older than "x" days
  • Possibly add additional APIs for cloud storage
  • Clean up the documentation
  • Other things
