Habitat from System Garden is a performance monitor of applications and operating system with the ability to track availability and service level. System Garden Habitats design goals are to be of modest size, flexible and ubiquitous.

The core of habitat provides a mechanism for collecting, storing and distributing data. Out of the box are many useful system collectors, known as probes.

Additionally, there is an API available to extend the collector (known as clockwork) with plug-ins, which allows data to be pulled from applications. Another API and a command line interface lets applications and scripts of all types push information into the collection system.

system-tools-backends is a package for GNOME.

to extract the configuracion

backend --get

to restore the configuration from XML

backend --set < file.xml

Twisted Storage is an application that will take your data and manage it for you, just like a file system. But Twisted Storage goes way beyond what a normal file system does.
What types of "objects" are stored in Twisted Storage : just regular files. The data stored in the system is expected to be fixed content, meaning it doesnt change at all. If you read the data back, change it, and store it, it is considered a different file. There are plenty of examples of fixed content data : emails you received, movies or mp3 files you made or own, documents you wrote, etc. In fact it is estimated that 80% of the data you have on your computer is fixed, reference data.
Your Twisted Storage system can start out small - a single computer with a few disk drives. When you need more storage you can add more disk drives and more computers. But it has been designed to store petabytes worth of data without requiring any special hardware. For example storing a petabyte worth of data, using the biggest disk drives available today (500 GB), would require 2000 disk drives. To overcome the need of special hardware, Twisted Storage is a scalable, distributed system using ordinary commodity computers. Even so that petabyte of data would require 500 computers networked together and that requires special handling.
Twisted Storage has a few features you wont find in any file system. For example once a file is added to the Twisted Storage repository it can be written in multiple locations simultaneously. The system has been designed to be compliant with Sarbanes-Oxley Act: when an object is added to the repository you can no longer delete it and the integrity of the contents are guaranteed. In addition any access to the object is recorded.
Main features:
Scalable to thousands of servers and multiple petabytes of data.
- Regardless of how much data you want to store,Twisted Storage is designed to handle it. The system can grow from one computer and a few disks to hundreds of systems and thousands of disk drivers.
Automatic data recovery without human intervention.
- Twisted Storage doesnt require backup/restore software or procedures. All data written to the system is recorded in multiple locations.
No special disaster recover procedures.
- So long as you have your systems in physically different locations and you have instructed the software to write the multiple copies to those systems, you have no-hassle disaster recover. If one of the sites goes down, the system will retrieve any data from the other systems. Additionally, once the disaster site is up and running, the system will automatically restore the data to the it.
Simplified configuration.
- To ease management of the system, you can change any one systems configuration and have it ripple through out the system.

That software writed in PHP, Perl and C, works with variuos database systems.

Timos rescue CD set provides an easy way to generate bootable CDROMs with a ready-to-use rescue system on them. The system is designed to be fully customizable and easy to build.
The rescue system includes reiserfs, parted, partimage, nmap, w3m, bash, sshd, telnetd, ftpd, and nfsd. It is based on Debians "Sarge" release. LILO, syslinux, isolinux, and GRUB are supported.
The project is evolving more and more into a "Debian on CD" project, which means that its use is not limited to a rescue CD; it is also possible to install a whole Debian system on CD.
Enhancements:
- the cdrecord script was buggy - fixed
