Introduction to Holland
Holland is an Open Source backup framework originally developed by Rackspace and written in Python. The original intent was to offer more reliability and flexilibity when backing up MySQL databases, though the current version is now able to backup MySQL and PostgreSQL databases. Because Holland is plugin-based framework, it can conceivably backup most anything you want by whatever means you want.
Holland is built around the concept of providers and backup-sets.
A provider implements a backup solution. This can range from backing up MySQL databases using mysqldump, LVM, or Xtrabackup; or PostgreSQL. holland is a pluggable framework, so other backup providers can be created beyond these as well.
A backup-set defines a backup and includes global parameters, such as which provider will be used and how many backups to keep; as well as provider-specific configuration options, such as databases to exclude, user credentials, servers, etc. While some providers share similar options with each other, for the most part each provider has its own set of configuration options.

The core Holland framework has the following dependencies (available on any remotely modern Linux distribution):
MySQL based plugins additional require the MySQLdb python connector:
For Red-Hat Enterprise Linux 5, all dependencies are available directly from the base channels. For Red-Hat Enterprise Linux 4, EPEL is required for python-setuptools.
Note that other plugins may have additional dependency requirements.
Holland has ready-made packages available for Red-Hat, CentOS, and Ubuntu which are available via the OpenSUSE build system. Other distributions may download the generic tarball or pull directly from github.
