In my last post I introduced ZPAQ and sang it's praises.

However, the fact that it's faster than Gzip,Bzip2 and XZ and produces smaller files than all of them is not why I fell in love with it.

It's ability to do incremental backups is.

In this post I'll …

So far we've gone through the ZPAQ basics and saw how to create incremental backups.

In this post I'll be taking a look at remote backups.

To demonstrate this, I'm going to mount a remote filesystem using SSHFS.

1. Install SSHFS

yum install epel-release -y
yum install fuse-sshfs -y

ZPAQ is a "incremental, journaling command-line archiver". I was impressed by it's capabilities and decided to do some quick tests with it:

yum install http://download …

This is my first attempt at using Let's Encrypt. Let's Encrypt is an SSL Certificate Authority -- which is completely free and open.

All hosts …

It turns out that installing Apache 2.4 on CentOS 6.6 is a bit of a pain.

These are the notes I compiled after a lot of effort and many Google searches :) Scroll to the bottom for the sources!

Install the Development tools and dependencies:

Quick notes on how to create a Yum repository and mount it over SSHFS as a local repo.

On the server side (that is where the Yum repo actually lives):

1. Install the "createrepo" package:

yum install createrepo -y

2. Create a directory to use as the repo container:

Some time ago I was working on a project where we only wanted to process the new files from a logfile - the requirement was that we should never process the same line more than once.

So we started counting the lines of the logfile and adding a bunch of checks …

Recently I've been working on a project where we had a need to put together some shell scripts in a package to use in CentOS servers.

We could have easily tarred them up, but then updating a bunch of servers consistently whenever we had an upgrade would be a pain …
