Bacula pruning old storage

I note with some amusement the fact that I wrote on this exact day last year about this same subject (in much more detail). The reason for the new message on this subject is that I'm still cleaning up some of the decisions I made when first using Bacula. The …

Renaming Elasticsearch indexes

I've been an ELK Stack (Elasticsearch, Logstash, Kibana, and Beats) user for quite some time, using exclusively the open source version fo the stack. Generally it's works well and, with some exceptions, supports our mostly-Solaris based environment (using LX zones to host most of the beefier components, and using custom-built …

First look 2021 M1 MacBook Pro

I last bought a MacBook Pro from Apple in November of 2019, in the midst of a bout of travel that was about to come to an end. In point of fact, I haven't used my trusty MacBook Pro much in the last 19 months, since the COVID-19 pandemic started …

Bacula pruning

After 18 months of using Bacula and sending copies of my data to the cloud (in this case, cloud I operate in another location) using an S3-compatible storage mechanism, I noticed I had a lot of data sitting around on my current server for backups. When I set out to …

Rclone to the rescue

Back in September of last year, I wrote in Bacula: 6 months on that cloud backups required part.0 in order to be recognized for automatic part retrieval. While this was mostly accurate, the critical file is actually part.1. As such, when referencing my own blog post when trimming …

GitLab stuck MR

MRs (Merge Requests) in GitLab are similar to PRs (Pull Requests) in GitHub, although the process and language around them are slightly different. The name specifically refers the the request to merge into another branch from a branch (or repository) that isn't the same. Simple enough. Most of the time …

Pelican plugin updates

One of the advantages of our recent pivot to gitlab is that I'm spending some time looking at existing repositories and doing some updates. Most of my repos are private and hosted on our private gitlab server. For public code, I generally place it on GitHub. With the recent automation …

Deploying with Gitlab

In June, I mentioned in an article about Docker on SmartOS that we are doing some work with GitLab these days as a replacement for my venerable Gitolite server (and, to an increasing extent Jenkins). Deploying from Pelican I'm likely going to write more on GitLab in the near future …

Docker on SmartOS

This spring, there was a some movement on the Illumos/SmartOS front in implementing features to better support running LX zones with Linux variants. Since Docker images (generally) run on Linux underpinnings, support for running Docker images on SmartOS are dependent upon this support working correctly. For those familiar with …

Pivoting Elasticsearch data

As I've possibly mentioned here before, ClueTrust is using Elasticsearch to perform analysis of log information. Recently, I finally decided to take some our telemetry inforamtion and pull it in to Elasticsearch as a data exploration and statistical tool. Importing structured XML data into Elasticsearch Although there are some filters …

Always check your arguments

Quite a while back, RS wrote a comprehensive ansible role for handling Let's Encrypt certificate issuance and renewal. We both use this role extensively, which is why it was a significant issue when it suddenly started throwing type errors deep inside of the dnspython library during an nsupdate call in …

2021 Backup Software

As we approach another World Backup Day, I figured it was time for me to revise my 2013 backup article for a more up-to-date view of what my backup situation is and what I am currently recommending. My basic backup strategy, as outlined in the previous article, hasn't changed significantly …

pre-commit and Pelican

Putting pre-commit to use I mentioned in a previous post about pre-commit, a tool for maintaining code consistency through simple management of pre-commit checks. The first place I decided to give this a whirl was on my blog sites. As you may be aware, I moved my blog sites (both …

pre-commit

Introducing pre-commit hooks I recently became aware of the open-source project: pre-commit, which is "A framework for managing and maintaining multi-language pre-commit hooks." The key feature of pre-commit is that it creates an execution environment for itself in order to enable running hooks without messing with (or creating conflicts with …

Bacula Restore Testing

Originally this was going to contain a brief Bacula, 6 months on section at the start. Of course, that became much too detailed, so I split them up, however I would encourage you to read it. Restore Testing Backup is the most obvious part of doing backups. Almost everyone's aware …

Bacula 6 months on

It's been about six months since I originally wrote Welcome Bacula, describing our transition to Bacula from our previous solution (and a bit of history even before that). If you haven't read it, it might be worth a read. Although not quite 6 months since I wrote the first piece …

Trapped in the ice

We've heard it all before: AWS is expensive, and you need to watch out for the hidden sharp edges of their pricing model. Today I provide a small lesson in that concept. History ClueTrust has run through a number of backup methodologies over the year, originally using Retrospect (when they …

Static pages-18 months on

In 2018, I wrote about the move to convert Gaige's Pages to a static generation model. I followed this up in mid-December of that year describing the drop in processing and response time. After 18 months of running the site (and Cartographica's Blog as well) on Pelican, I wanted to …

So much LDAP, so little time

The background Many years ago, all of my systems were pets. I tried to make them easier to manage by standardizing on a single operating system (MacOS X Server at the time) and used management tools that were part of that suite. As time moved forward, Apple decided to concentrate …

Welcome Bacula

I wasn't originally going to write this up on the blog, but considering that we've just finished our transition from our old backup software (BRU, no link) to Bacula community edition and considering that it's World Backup Day, it seemed like it would make sense. As many of you are …
