rsync-mirror is used to backup local directories to another location on the local machine or to a remote machine. As the name suggests, it uses rsync for data transfer so it should be pretty efficient. It does not support any nifty backup features like incremental backups; all it does is mirror a directory to another location. To ease the task of creating backups, rsync-mirror takes care of managing the destination site of the backup. In case the target path needs to be mounted, rsync-mirror does so before backup and unmounts it afterwards.
BinBackup is a tool intended to efficiently back up a directory to a set of size-limited media like CD-Rs or DVD-Rs. It's goal is to distribute the contents of a directory to a set of media while using the space available on these media as best as possible, minimizing the number of media required for a backup. To do this, BinBackup uses a bin packing algorithm to decide how to partition the contents of a directory and where to put them.
OpenNebula is a toolkit to easily build any type of cloud: private, public, and hybrid. OpenNebula has been designed to be integrated with any networking and storage solution and so to fit into any existing data center. OpenNebula orchestrates storage, network, and virtualization technologies to enable the dynamic placement of multi-tier services (groups of interconnected virtual machines) on distributed infrastructures, combining both data center resources and remote cloud resources, according to allocation policies.
BitNami Spree Stack greatly simplifies the deployment of Spree and its required dependencies. It can be deployed using a native installer, as a virtual machine, in the cloud, or as a module over an already installed infrastructure stack. Spree is a very powerful and flexible e-commerce platform written for the Ruby on Rails framework.
spuug is a little tool that generates the boilerplate code for GObjects. spuug can be used for "plain" GObjects, but also for more sophisticated objects such as GTK+ widgets. It tries to be a bit smart with the code in spits out. However, understanding of GObjects/GtkWidgets is recommended.
