Easy Automated Snapshot-Style Backups with Linux and Rsync

Post date: February 1, 2006, 00:02 Category: Software Views: 3808 Comments
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.

Hide your folders in KDE

Post date: November 11, 2007, 05:11 Category: Desktop Views: 3773 Comments
Tutorial quote: Want to keep your MP3s away from your boss’ or big brother’s view? Of course, in Linux anything that starts with a period is “suppose” to be hidden; but all we have to do is type “ls -A” or turn on the viewing of hidden files in KDE…not too hard. Basically what we can do is set a transparent PNG as our folder icon, and rename our folder with a ” “(space). This will actually keep the previous name of the folder.Also we will keep anyone out of the folder that doesn’t know Linux commands, and doesn’t know exactly where we have placed the icon. This works GREAT for the desktop.

The PartImage Handbook

Post date: May 21, 2005, 15:05 Category: Software Views: 3172 Comments
Tutorial quote: - Partition Image is a Linux/UNIX partition imaging utility: it saves partitions formatted using the Ext2FS (the linux standard), ReiserFS (a new journaled and powerful file system), JFS IBM journaled file systems from AIX, NTFS (Windows NT File System), FAT16/32 (DOS & Windows file systems), or HPFS (OS/2 file system) file system formats to an image file. Only used blocks are copied. The image file can be compressed in the GZIP/BZIP2 formats to save disk space, and split into multiple files to be copied on removable media (ZIP for example), or burned on a CD-R ...

- This allows the user to save a full Linux/Windows system, with a single operation. When problems occur (viruses, crash, error, ...), you just have to restore, and after several minutes, all your system is restored (boot, files, ...), and fully working.

- This is very useful when installing the same software on many machines: just install one of them, create an image, and then restore the image on all other machines. After the first one, each subsequent installation can be made automaticaly, and only requires a few minutes.

Building a Linux virtual server

Post date: June 9, 2005, 14:06 Category: Software Views: 3654 Comments
Tutorial quote: With the explosive growth of the Internet, the workload on servers providing Web, email, and media services has increased greatly. More and more sites are being challenged to keep up with the growing demands and are employing several techniques to avoid overloading their servers. Building a scalable server on a cluster of computers is one of the solutions that is being effectively put to use. With such a cluster, the increasing requests can be easily managed by simply adding one or more new servers to the existing cluster as required. In this article we will look at setting up one such scalable, network load-balancing server cluster using a virtual server via the Linux Virtual Server Project.

Setting up yum on SUSE LINUX 10.0

Post date: October 16, 2005, 16:10 Category: System Views: 6243 Comments
Tutorial quote: Why should I use yum and not yast? Well, yast is nice, but has some disadvantages: It can#t check for gpg keys, you have to trust the mirrors you add. And, speaking about mirrors, yast has no real mirror management for one source. Especially in these times the most and best known SUSE mirrors are very slow or just closed down, so you have to add other sources in yast. But yast needs your clicks when a mirror is not reachable, and if you enter several sources just as mirrors, it checks every single source - that takes quite a long time!
A last reason (which is not important know because SUSE LINUX has a ugly workaround) is that yast is not able to handle packages for different architectures - it can only install packages for one architecture.
