Everything Linux - A Tutorial on Using Rsync. Perl problem. How to create and extract zip, tar, tar.gz and tar.bz2 files in Linux. Data compression has been extremely useful to us over the years. Whether its a zip file containing images to be sent in a mail or a compressed data backup stored on a server, we use data compression to save valuable hard drive space or to make the downloading of files easier. There are compression formats out there which allow us to sometimes compress our data by 60% or more.
I’ll run you through using some of these formats to compress and decompress files and directories on a Linux machine. We’ll cover the basic usage of zip, tar, tar.gz and the tar.bz2 formats. Before we delve into the usage of the formats I’d like to share some of my experience using the various formats of archiving. Zip is probably the most commonly used archiving format out there today. To compress a directory with zip do the following: # zip -r archive_name.zip directory_to_compress Here’s how you extract a zip archive: # unzip archive_name.zip Tar is a very commonly used archiving format on Linux systems.

Ubuntu Studio 11.10 - Page 5. 9 Google Earth In chapter 6, we have installed the package googleearth-package which is a utility to automatically build a .deb package of Google Earth. This means, Google Earth is not yet installed; we have to first build a .deb package of it with the help of googleearth-package, and then install the .deb package. Open a terminal (System > Terminal) and become root: sudo su Now you can build the Google Earth .deb package as follows: make-googleearth-package --force If you don't see any errors, then you should find the Google Earth .deb package in the current directory: ls -l Now you can install Google Earth as follows: gdebi googleearth_6.0.3.2197+0.6.0-1_amd64.deb 10 Inventory (II) Now let's check again what we have so far by browsing the menus again: (JavaScript must be enabled in your browser to view the large image as an image overlay.)

Advanced or manual disk partitioning is available for those that want to create a custom set of partitions for installing Ubuntu 11.04. For whatever reason or reasons you choose to use the advanced disk partitioning tool, this article gives a step by step guide, with detailed explanations, on how to do it. This tutorial assumes that you are going to create partitions for a standalone installation of Ubuntu 11.04.
If you are going to create partitions for dual-booting with Windows or another Linux distribution, a future article, to be published soon, will provide instructions on how to create partitions manually, when dual-booting. On a default installation of Ubuntu 11.04, the installer creates just two partitions; the first for /, the root directory, and the second for Swap. When creating partitions for installing any desktop Linux distribution, my recommendation is to create the following four partitions: /boot, the boot partition.

Purpose of Postfix performance tuning The hints and tips in this document help you improve the performance of Postfix systems that already work. If your Postfix system is unable to receive or deliver mail, then you need to solve those problems first, using the DEBUG_README document as guidance. For tuning external content filter performance, first read the respective information in the FILTER_README and SMTPD_PROXY_README documents. Then make sure to avoid latency in the content filter code. As much as possible avoid performing queries against external data sources with a high or highly variable delay. Topics on mail receiving performance: Topics on mail delivery performance: Other Postfix performance tuning topics: The following tools can be used to measure mail system performance under artificial loads. General mail receiving performance tips Read and understand the maildrop queue, incoming queue, and active queue discussions in the QSHAPE_README document.

Parameters not explicitly specified are left at their default values. The remainder of this document is a description of all Postfix configuration parameters. Default values are shown after the parameter name in parentheses, and can be looked up with the "postconf -d" command.

Page last modified 2004.01.04 Updates: As of rsync-2.5.6, the --link-dest option is now standard! That can be used instead of the separate cp -al and rsync stages, and it eliminates the ownerships/permissions bug. I now recommend using it. Also, I'm proud to report this article is mentioned in Linux Server Hacks, a new (and very good, in my opinion) O'Reilly book by compiled by Rob Flickenger. Contents AbstractMotivationUsing rsync to make a backup Basics Using the --delete flag Be lazy: use cronIncremental backups with rsync Review of hard links Using cp -al Putting it all together I'm used to dump or tar!
This seems backward! Abstract 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. Motivation Note: what follows is the original sgvlug DEVSIG announcement. Ever accidentally delete or overwrite a file you were working on? Using rsync to make a backup Basics. Examples of using rsync. Some of the main features of rsync include can update whole directory trees and filesystemsoptionally preserves symbolic links, hard links, file ownership, permissions, devices and timesinternal pipelining reduces latency for multiple filescan use rsh, ssh or direct sockets as the transportchecksum based verification Preserving permissions, updating whole directory trees and secure transfers over ssh makes this the ideal backup tool. And it can be easily scheduled using cron. It’s also incredibly fast if you make us of the rsync daemon and not ssh.
This article will cover a few examples so that you’ll be able to quickly make use of the primary features of rsync. Things to note when you use rsync Copy the /home/temp folder to the remote-host $ rsync -v /home/temp/ username@remote-host:/home/temp/ Copy the folder & the files within /home/temp to the remote host $ rsync -v /home/temp/* username@remote-host:/home/temp/ Copy the folder & the files within /home/temp to the remote host. // CrashMAG. Using Rsync and SSH. Using Rsync and SSH Keys, Validating, and Automation This document covers using cron, ssh, and rsync to backup files over a local network or the Internet. Part of my goal is to ensure no user intervention is required when the computer is restarted (for passwords, keys, or key managers). I like to backup some logging, mail, and configuration information sometimes on hosts across the network and Internet, and here is a way I have found to do it.
You'll need these packages installed: rsyncopensshcron (or vixie-cron) Please note these instructions may be specific to Red Hat Linux versions 7.3, 9, and Fedora Core 3, but I hope they won't be too hard to adapt to almost any *NIX type OS. First, I'll define some variables. I want to make sure that 'rsync' over 'ssh' works at all before I begin to automate the process, so I test it first as thisuser: $ rsync -avz -e ssh remoteuser@remotehost:/remote/dir /this/dir/ and type in remoteuser@remotehost's password when prompted.
