- How To Back Up An Ubuntu 8.10 System With SystemImager
SystemImager lets you create images of your Linux installations. To do so, you need an image server (should have enough disk space to store your images) and a so-called golden client (i.e., the system of which you want to make an image). This means that you have to install some software on your image server and on your golden client in order to run SystemImager. This tutorial shows how to install a SystemImager server and a SystemImager client, both using Ubuntu 8.10, and how to create/update/restore/delete images.
- How To Back Up MySQL Databases With mylvmbackup On Ubuntu 12.10
mylvmbackup is a Perl script for quickly creating MySQL backups. It uses LVM's snapshot feature to do so.

This article shows how to use it on an Ubuntu 12.10 server.
- How To Back Up MySQL Databases Without Interrupting MySQL | HowtoForge
This article describes how you can back up MySQL databases without interrupting the MySQL service. Normally, when you want to create a MySQL backup, you either have to stop MySQL or issue a read lock on your MySQL tables in order to get a correct backup; if you do not do it this way, you can end up with an inconsistent backup. To get consistent backups without interrupting MySQL, I use a little trick: I replicate my MySQL database to a second MySQL server, and on the second MySQL server I use a cron job that creates regular backups of the replicated database.

- How To Block Spam Before It Enters The Server (Postfix)
The last few weeks have seen a dramatic increase in spam (once again). Estimates say that spam makes now up for 80 - 90% of all emails, and many mail servers have difficulties in managing the additional load caused by the latest spam, and spam filters such as SpamAssassin do not recognize large parts of that spam as they did before. Fortunately, we can block a big amount of that spam at the MTA level, for example by using blacklists, running tests on the sender and recipient domains, etc. An additional benefit of doing this is that it lowers the load on the mail servers because the (resource-hungry) spamfilters have to look at less emails.

Torrent is a great way to transfer large files very quickly. However most torrent clients are gui based and have quite some impact on system resources (e.g. Azureus). rTorrent is a lightweight client running from the terminal. Being able to run it in a screen session (also upon boot) makes it ideal to also control it from a remote location.
