Tar - fast and medium effective, don't support password
Zip - fast and medium effective, support password
7zip - very slow and very effective, support password

Splitters supported:

ZipSplit - split a zipfile into smaller zipfiles

Installation (>=Symfony 2.1)

Composer

Download CloudBackupBundle and its dependencies to the vendor directory. You can use Composer for the automated process:

$ php composer.phar require dizda/cloud-backup-bundle "~1.6"

Composer will install the bundle to vendor/dizda directory.

Adding bundle to your application kernel

// app/AppKernel.php

public function registerBundles()
{
    $bundles = array(
        // ...
        new Knp\Bundle\GaufretteBundle\KnpGaufretteBundle(),
        new Dizda\CloudBackupBundle\DizdaCloudBackupBundle(),
        // ...
    );
}

Configuration

Here is the default configuration for the bundle:

dizda_cloud_backup:
    # By default backup files will have your servers hostname as prefix
    # such as: hostname_2014-01-01_21-08-39.tar
    output_file_prefix: hostname
    timeout: 300
    processor:
        type: tar # Required: tar|zip|7z
        options:
            compression_ratio: 6
            password: qwerty
            # Split into many files of `split_size` bytes
            split:
                enable: false # Default false
                split_size: 1000 # Make each zip files no larger than "split_size" in bytes
                storages: [ Dropbox, CloudApp, GoogleDrive, Gaufrette ] # Which cloud storages will upload split files
    folders: [ web/uploads , other/folder ]
    cloud_storages:
        # Dropbox account credentials (use parameters in config.yml and store real values in prameters.yml)
        dropbox:
            user:     ~  # Required
            password: ~  # Required
            remote_path: ~ # Not required, default "/", but you can use path like "/Accounts/backups/"
        # CloudApp account. Can be optional, like dropbox.
        cloudapp:
            user:        ~ # Required
            password:    ~ # Required
        # or you can use Gaufrette as well (optional)
        gaufrette:
            service_name: ~  # Gaufrette filesystem service name
        google_drive:
          token_name: ~ # Required
          remote_path: ~ # Not required, default "/", but you can use path like "/Accounts/backups/"

    databases:
        mongodb:
            all_databases: false # Only required when no database is set
            database:     ~ # Required if all_databases is false
            db_user:     ~ # Not required, leave empty if no auth is required
            db_password: ~ # Not required

        mysql:
            all_databases: false # Only required when no database is set
            database: ~          # Required if all_databases is false
            db_host: localhost   # This, and following is not required and if not specified, the bundle will take ORM configuration in parameters.yml
            db_port: ~           # Default 3306
            db_user: ~
            db_password: ~

        postgresql:
            database: dbname     # Required
            db_host: localhost   # This, and following is not required and if not specified, the bundle will take ORM configuration in parameters.yml
            db_port: ~           # Default 5432
            db_user: ~
            db_password: ~

It is recommended to keep real values for logins and passwords in your parameters.yml file, e.g.:

# app/config/config.yml
dizda_cloud_backup:
    processor:
        type: tar
        options:
            password: %dizda_cloud_archive_password%

    cloud_storages:
        dropbox:
            user:        %dizda_cloud_dropbox_user%
            password:    %dizda_cloud_dropbox_password%
            remote_path: %dizda_cloud_dropbox_remote_path%

    databases:
        mongodb:
            all_databases: false
            database: %dizda_cloud_mongodb_user%
            db_user:  %dizda_cloud_mongodb_user%
            db_pass:  %dizda_cloud_mongodb_password%

        mysql:
            # When no parameters is specified under mysql, the bundle taking those from parameters.yml

        postgresql:
            # When no parameters is specified under postgresql, the bundle taking those from parameters.yml

# app/config/parameters.yml
	# ...
    database_driver: pdo_mysql
    database_host: localhost
    database_port: null
    database_name: myDatabase
    database_user: myLogin
    database_password: myDatabasePassword
    # ...
    dizda_cloud_dropbox_user:     myDropboxUser
    dizda_cloud_dropbox_password: MyDropboxPassword
    dizda_cloud_mongodb_user:     mongodbUser
    dizda_cloud_mongodb_password: mongodbPass
    dizda_cloud_archive_password: ArchivePassword
    # ...

Usage

The bundle adds one command to symfony console: app/console dizda:backup:start which you execute periodically as a cron job. For example the following cron command dumps your database every days at 6am on a server :

# m h  dom mon dow   command
0 6 * * * php /opt/www/symfony-project/app/console dizda:backup:start

Info : To edit crontab for the user www-data (to prevent permissions error) :

$ crontab -u www-data -e

or simply

$ php app/console dizda:backup:start

You may point concrete archiver in command line:

$ php app/console dizda:backup:start zip

In addition, using -F or --folder option the folders also will be added to the backup.

Obviously, if some problems occurs during the backup process, you can configure monolog to send you emails.

Which archiver do I use?

tar and zip archivers are produce the same size of compressed file, but tar compresses faster. 7z archiver is very slow, but has double effectiveness. tar archiver do not support encryption, other archivers support.

Note Your system may not have the zip and 7z archivers installed. But tar is installed in common case.

Guide to choice:

If you don't need password protection and you have enough disk space, the best choice is tar.
If you need password protection and you have enough disk space, the best choice is zip.
If you haven't enough disk space (or you will do backup often) and you backup only text data (e.g. database dumps), the best choice is 7z.

Note Any archiver good compress text files (and better compress structured texts e.g. sql, css, html/xml). But binary files (images, audio, video) will not be well compressed. If you have small database dump and big binary data, the best choice will be tar or zip.

Comparison of archivers

Uncompressed archive contents sql dump of 42.2M size. This table represents effectiveness of archivers. Third column contents compressed archive file and percent of compression (low is better). Fourth column contents compression time and its ratio (to first line) (low is better).

archiver	compression	archive size	execution time
tar	default (6)	8.78M (20.8%)	4.44s (1.00x)
tar	best (9)	8.45M (20.0%)	9.89s (2.23x)
zip	default (6)	8.78M (20.8%)	5.39s (1.21x)
zip	best (9)	8.45M (20.0%)	11.03s (2.48x)
7z	default (5)	4.42M (10.5%)	31.06s (7.00x)
7z	best (9)	4.24M (10.0%)	38.88s (8.76x)

Capifony integration

If you are using capifony for deployment you can grab the sample task for easier backups.

Add the following task in your deploy.rb file

namespace :symfony do
    namespace :dizda do
        namespace :backup do
            desc "Upload a backup of your database to cloud service's"
            task :start do
                run "#{try_sudo} sh -c 'cd #{current_release} && #{php_bin} #{symfony_console} dizda:backup:start #{console_options}'"
            end
        end
    end
end

This adds symfony:dizda:backup:start command to capifony. To launch it automatically on deploy you might use:

# 1) Launches backup right before deploy
before "deploy", "symfony:dizda:backup:start"

# 2) Launches backup after deploy
after "deploy", "symfony:dizda:backup:start"

End

This bundle was inspired from KachkaevDropboxBackupBundle.

It is Symfony2.1, 2.2 and 2.3+ compatible.
