Magedbm - Magento Database Backup Manager

Provides a simpler way for developers to retrieve sanitised Magento database backups without requiring server access.

It's design to run on production boxes to create database dumps and upload to Amazon S3 buckets.

It can then be run on local development machines to get latest or specific backup for a project and automatically import it.

Works particularly well when partnered with mageconfigsync.

Motivation

Working on Magento client sites typically requires a fresh copy of the production database in order reduce discrepencies later in the development cycle due to differences between environments. This can be difficult to achieve a number of reasons and either way will slow down development process.

Compatibility

Compatible with PHP 5.3+. Uses a PHP alternative for creating database backups when exec is disabled.

Installation

Download the phar.

wget https://s3-eu-west-1.amazonaws.com/magedbm-releases/magedbm.phar

Make sure it's executable

chmod +x ./magedbm.phar

Copy to /usr/local/bin/ to make it available system-wide.

sudo cp ./magedbm.phar /usr/local/bin/

Setup

To give you an example of possible setup, the following is provided which avoids the need to have numerous buckets which would then need to be specified on every command.

Create a bucket, e.g. 'magedbm'. All developers should have access to this bucket.

For each production box that is creating backups a new S3 user will need to be created with the "IAM Management Console". We create a policy which enables them to list contents of the bucket but only download files that they have access to. That means the only information leak is the names of files (client names). This is the policy that we use:

 {
     "Version": "2012-10-17",
     "Statement": [
         {
             "Effect": "Allow",
             "Action": "s3:ListAllMyBuckets",
             "Resource": "arn:aws:s3:::*"
         },
         {
             "Sid": "Stmt1441615435000",
             "Effect": "Allow",
             "Action": [
                 "s3:ListBucket"
             ],
             "Resource": [
                 "arn:aws:s3:::magedbm"
             ]
         },
         {
             "Effect": "Allow",
             "Action": [
                 "s3:*"
             ],
             "Resource": [
                 "arn:aws:s3:::magedbm/clientname*"
             ]
         }
     ]
 }

Usage

Configure

Configure with AWS credentials.

 magedbm configure [-k|--key="..."] [-s|--secret="..."] [-r|--region="..."] [-b|--bucket="..."] [-f|--force]

Upload Database

Dump database with customer and sales information stripped and upload to S3.

magedbm  put [-s|--strip[="..."]] [--no-clean] [--history-count="..."] [-r|--region="..."] [-b|--bucket="..."] name

List Available Databases

List database backups available for project.

magedbm ls [-r|--region="..."] [-b|--bucket="..."] name

Download & Import Database

Download chosen or latest database and import into Magento instance.

magedbm get [--file="..."] [-f|--force] [-d|--drop-tables] [-r|--region="..."] [-b|--bucket="..."] name

Delete Database Backups

Delete old backups from S3.

magedbm rm [-r|--region="..."] [-b|--bucket="..."] name file

Development

Packaging Phar

We use box project for creating a phar. The configuration for which is found in box.json.

To build, change to the project root and run:

box build

If you run into the following error:

PHP Fatal error:  Uncaught exception 'ErrorException' with message 'proc_open(): unable to create pipe Too many open files'

Then increasing the limit by running this seems to be a solid workaround:

ulimit -Sn 4096

Creating Release

After creating a release according to meanbee standards, the phar can be attached to the release on github.

It also needs to be uploaded to the magedbm-releases bucket in Meanbee's S3 account. We upload one version as magedbm.phar and another with the version in it magedbm.1.3.0.phar.

In order for the self-update command to know about the new release, the manifest.json file (also in the magedbm-releases bucket) requires update. Create a new entry in the releases array to point to the latest version. To create the SHA which is used for valiation upon update run this command:

shasum -a 1 ./magedbm.phar

For any files uploaded, make sure that they're made public by clicking on Properties so that external uses to Meanbee can access.
