Unix+clones Easy Automated Snapshot-Style Backups with Linux and Rsync
Post date: January 31, 2006, 19:01 Category: Software Views: 27
Tutorial quote: This document describes a method for generating automatic rotating "snapshot"-style backups on a Unix-based system, with specific examples drawn from the author's GNU/Linux experience. Snapshot backups are a feature of some high-end industrial file servers; they create the illusion of multiple, full backups per day without the space or processing overhead. All of the snapshots are read-only, and are accessible directly by users as special system directories. It is often possible to store several hours, days, and even weeks' worth of snapshots with slightly more than 2x storage. This method, while not as space-efficient as some of the proprietary technologies (which, using special copy-on-write filesystems, can operate on slightly more than 1x storage), makes use of only standard file utilities and the common rsync program, which is installed by default on most Linux distributions. Properly configured, the method can also protect against hard disk failure, root compromises, or even back up a network of heterogeneous desktops automatically.
Debian Automated distributed backups for laptops
Post date: February 14, 2006, 16:02 Category: Network Views: 42
Tutorial quote: This document will describe the setup I made for automating the backup tasks for all laptops here in the house. My servers use the same backup server and infrastructure, but right now they don't have the checks and scripts because they are online 24/7 and my backup server is triggering the backup process. This is however not true at all for the laptops.

Laptops can be at different places, powered down, suspended, put to sleep etc. So I needed a different approach for them.
Linux Automating Builds on Linux
Post date: April 12, 2005, 20:04 Category: Miscellaneous Views: 41
Tutorial quote: An automated nightly build is a process for building an application every night using an infrastructure that automatically executes the required steps at the scheduled time, without any human intervention. A well-planned build process not only builds your application, but also provides you and your team with early detection of incompatible changes in the application components and early detection of errors introduced by newly integrated code. When configured and used properly, automated builds are a critical component for ensuring that the application satisfies quality requirements and continues to run as expected.
Unix+clones Unattended, Encrypted, Incremental Network Backups

Tutorial quote: If you use Linux, you already have access to extremely powerful tools for creating custom backup solutions. The solutions in this article can help you perform simple to more advanced and secure network backups using open source tools that are part of nearly every Linux distribution.
Debian An Introduction to Video Surveillance with 'Motion'
Post date: February 6, 2006, 04:02 Category: Security Views: 58
Tutorial quote: Videochatting and amateur pornography are all well and good, but have you ever wondered what else you can do with that webcam?
Well, thanks to the efforts of many dedicated open-source coders, any half-decent PC can be turned into a motion-detecting, snapshot-making, video-recording D.I.Y. security solution.
Linux Building a Linux video jukebox for an anime convention
Post date: November 25, 2005, 16:11 Category: Miscellaneous Views: 125
Tutorial quote: I wrote this little whitepaper a while back for Amy Zunk to document the function of the VideoKeg/VideoJukebox boxes. Documented here for posterity. The primary goal of the video keg was to build a reliable video box that was easy to transport with enough space to store 3 days worth of Anime fan-subs.

The secondary goal of the video keg was to make a home PVR system for video playback and time-shifting, along with a video arcade and perhaps a web browser. The tertiary goal of the video keg was to find an affordable hardware platform so that we could buy 4 of them immmediately to service the primary goal's need for 4 separate video rooms.

For a PVR, the machine neeed to be small, quiet, low-heat, and still fast enough to run the software video player and arcade games. For portability, we decided to go with a smaller mini-ITX style cube box.

Mepis Upgrading to Linux from Windows 98
Post date: April 18, 2005, 03:04 Category: Miscellaneous Views: 134
Tutorial quote: In this tutorial-style article, Michael C. Barnes outlines a strategy to avoid costly upgrades from Windows 98 to Windows XP -- in terms of both hardware and software -- by upgrading to Linux, instead. Barnes reviews the typical requirements of computers used for relatively generic purposes, and shows how to give a new lease on life to aging laptops and PCs by replacing obsolete OSes such as Windows 98 with a combination of Linux, free open source applications, and inexpensive commercial software.
Unix+clones Using network transfer protocols
Post date: April 15, 2005, 14:04 Category: Network Views: 38
Tutorial quote: Let's face it, most of us are in a rut when it comes to moving our files around. We learned how to use a simple FTP client years ago, and maybe even updated to a GUI FTP client when we were feeling particularly adventurous. There are actually a wealth of tools available for transferring files, and some of them perform automation functions that can easily assist your business in building site mirrors, synchronizing directory contents, and more.

Keep in mind that for many of the tools covered here, there's only really room to skim through their features. Some, such as wget and rsync, are full of useful capabilities for those brave enough to read their man pages and experiment.
