MO Backup: Main Page
Summary
Introduction to the MO Backup module
The MO Backup module was created by Made to Order Software Corporation.
In order to manage a large number of websites, it is necessary to support a mechanism to keep a backup of those websites. The backup should include all the dynamic files.
The dynamic files are:
- The files found in the directory where users upload files (i.e. sites/<name>/files/*)
- The settings.inc file (although it does not change much if at all over time, it is important to back up this file since without it you cannot immediately access the website database)
- The database
This module proposes to save all those dynamic files on a per website basis. We use it with our multi-site installation and it works like a charm.
It is possible to independently configure whether the files and the database are to be backed up.
- Note:
- This works with websites that are a few hundred pages or less. For websites that are larger (thousand of pages), it is adviced that you find a database replicator. The MO Backup can still be used for the dynamic files, though.
- Todo:
- Properly extract the Drupal database extensions (i.e. unsigned integers and a few other types and functions.)

Requirements
This module requires the following functionality on your system:
- The tar utility (to restore a backup)
- The gzip compressor (to restore a backup)
- The pg_dump utility (to backup the database)
- The pg_restore utility (to restore the database)
- A valid CRON functionality on your server
All of those tools are generally installed on Linux by default.
For MS-Windows, you can find tar and gzip on the http://www.mingw.org website.
pg_dump comes along with PostgreSQL. It is assumed that you are using PostgreSQL (obviously). This tool is directly used by the MO Backup system. On the other hand, the tar and gzip tools are not required on your server except when restoring a website.

Installation
In order to install this module:
- Extract the tarball under sites/all/modules
- On your server, feel free to delete the doc sub-folder (it is safe since it is just and only static HTML)
- Go to admin/build/modules and select MO Backup
Then go to admin/settings/mo_backup to change the backup setup.
By default, the files and database backups are turned on but you must specify a directory where backups will be saved. Until then, no backups will be performed.

Errors generated by this module.
This module generates an error if the destination folder specified for the backup files on the server is read-only or does not exist.
The module will also check whether the tar utility, the gzip utility and the PostgreSQL tools are all available from the server. You can ignore the tar and gzip errors until a restore is required.
